We did a 3-day 2-night trip, staying in garden bungalow park accomodation and visiting the 4 'show caves': Lang, Deer, Clearwater and Wind.
The caves themselves are awesome, especially Deer with its huge scale and Clearwater, with its miles of underground river. Large parts are easily accessible, with a guide, via well maintained walkways. The caves are set in primary rainforest; just walking to and from them and around the area in the evening, surrounded by the sounds of the forest, is a great experience in itself.
We booked through Borneo Adventure and had a great guide, Nelson, who was full of interesting information on the caves and the flora and fauna of the forest.
Food at the park cafe was good and reasonably priced. There is also a centre with loads of interesting information on the history biology and geology of the park.
Mulu is an amazing place, my favourite experience in over 2 weeks travelling in Sarawak and Sabah, and it's a world heritage site with good reason.

I never understood why anyone would find cave tours boring. Pictures really don't do them justice - you need to experience them yourselves. I always thought I'd be disinterested, but this is the third time I'm visiting any kind of caves and I still find them so fascinating. Mulu Caves are even better with their sheer size, I cannot be more amazed! From the bat exodus of the Deer Cave to the underground river in the Clearwater Cave, I really have nothing bad to say about them. Book the tours with the park itself, it's cheaper and the guides are super friendly!

I visited Mulu national park and its caves in December 2018 for 2 days. It is such a gem of a place and a must for anybody travelling to Borneo ! I booked a trip to see the wildlife in the north and wanted to squeeze in a quick visit to the caves, what was supposed to be an extra to my main adventure turned out to be the best part of my holiday. The park is beautifully run and the guides are knowledgeable and extremely friendly. Add it to your itinerary trust me on this!

Gunung Mulu is an amazing place. Did the 3 day/2 night option to include the 4 major caves and decided to treat myself to the Marriott which more than lived up expectations. As other contributors have said, just being in this area and so close to nature makes this place feel very special. The caves were all fantastic - different in their own ways and even getting to them is an experience, either trekking on paths through the jungle or boat trips down the swollen river. The wildlife on show was incredible too - the bat exodus has to be seen to be believed. One note, do not bother with Miri (Mulu is included in lots of Miri pages) - it is NOT Miri which is soulless place and not worth wasting 3 days in!!)

I am writing this long review to – hopefully – inform others who are planning to visit this amazing area so that they be better-informed, as information on the Internet can be lacking in details sometimes. I am also not giving away too much detail of the walks, so there is no spoiler. Just want to premise this review by stating that in the days we were there, the weather was sunny with just a couple of hours of rain, none of which were during the times we went for our walks. It is also based on my experience, and I cannot be sure if the same is applicable to everyone on the same trips. Lastly, for reference, do note that my fitness level is below average to that of a typical Singaporean man my age, which is in the mid-40s. While I do have experience with hikes, I do not do them regularly.
Our planned itinerary:
Day 1: Mulu Heritage Centre (free); Botanical Trail (free); Night Walk (guided)
Day 2: Wind and Clearwater Caves (guided; a.m.); Lang & Deer Caves (guided; p.m.)
Day 3: Long Langsat River Walk (guided; a.m.); Canopy Walk (guided; p.m.)
Pre-trip
Before the trip, I went online to do research on the area as well as the various tours offered. I decided to book the tours with the Park HQ. Hence, I emailed them with our details and the tours that I was interested in. I did this to ensure that the tours I wanted were not overbooked. I received a reply within the same day, confirming the bookings.
Day 1
We arrived at Mulu in the morning. After checking-in and taking a break, we took a hotel shuttle to Park HQ. There was quite a number of tourists at the Park HQ, but we were quickly served by an available staff. We settled the payment for the Park entry pass as well as the tours that we booked; efficiently well-served by the polite Park staff.
We then visited the Heritage Centre. Informative, pretty displays of the information about karst landscapes, rainforests, and Mulu in particular. Information that you would have known if you were into these things; but, otherwise, a good introduction if you are new to them.
Next door to it is the café; more on this later. Then there is the Mulu Gallery (i.e., gift shop). Some souvenirs and essentials can be found here. What is probably much needed are the rubber non-slip shoes that were selling for RM15. They are needed for the walks.
We then went on our own Botanical Walk. It is an easy walk on raised wooden platforms, with clear signs leading the way, near the Park HQ. It was good for an introduction around the area and the type of vegetation to expect as well as exposure to the heat and humidity. The walk took about 1.5 hours, leisurely paced.
In the evening, we went back to the Park HQ for the Night Walk. We met with a guide who brought us on the raised wooden platforms near the Park HQ, but on a different route. He showed us many insects, arachnids, and amphibians, raising our awareness to the different sounds of the forest. Although occurring in the dark, it was an easy walk. The guide did mention the possibility of seeing mammals like the civet cat or slow loris; however, we did not get to see any of those.
Day 2
This was the day of 4 cave visits. It began with a very pleasurable boat ride along the Sungei Melinau from the Park HQ to Batu Bangan, a Penan settlement. There were some handicrafts with pretty motifs on sale as well as a view (from the outside) of modern longhouses. There is no jetty to embark and disembark, requiring stepping into the river; hence, the rubber shoes bought at Day 1 comes into play.
Another short boat ride later, we arrived at a floating platform along the banks. This begins the climb up to Wind Cave. It is an easy ascent and a good introductory cave to look at the typical features of the cave, with an easy walk.
After the descent, we were given a choice to take a 2-minute boat ride to the next stop or a 10-minute walk along wooden platforms. I chose the former. Either choice leads us to a rest area: the Clearwater Cave Picnic Area. Other people on the tour who chose to walk seemed to arrive with ease and thus, I am guessing the walk was not too difficult. The rest area was a pleasant sheltered area with great views of the river and surrounding cliffs and vegetation.
The next cave was the Clearwater Cave. To access it, we needed to climb a relatively steep 200-step stairs. It took some effort for me but I did manage it in about 10 minutes. The walk inside this cave was longer, with more to see. The walk was easy for the most parts, with some steps to climb, but nothing as strenuous as when accessing the cave. We descended the same way we ascended.
After descent, we were given the choice of swimming at the waters at the Picnic Area or to catch the boat ride back to the Park HQ. We went back to the Park HQ and had lunch at the Park Café, while waiting for the noon walks to begin. Food portions were huge and made for a satisfactory meal.
The afternoon walks began at the Park HQ. We then followed the wooden platforms to take a longish walk to Lang Cave. We began covering the same areas walked on earlier trips but also got to areas not covered before, being further along the way. The walk, while long, was easy and we got to Lang Cave. An easy walk was had through Lang Cave, with interesting limestone features.
From Lang Cave, it was a short walk to Deer Cave. At the entrance of Deer Cave is a postbox; so if it so interests you, come with a postcard (with stamp affixed) to drop off here! Deer Cave is huge (to put it mildly) and hence, a much longer walk. While the walk is easy, the pong from the guano can be a tad overpowering. Yet, this was totally worth it as some of the most iconic features in Mulu are found here.
At the end of this trip, we sat at a nicely set-up rest area and watch the bat exodus - an amazingly stunning and humbling view.
Four caves so far within a day, and all is good. Each cave was sufficiently distinct that I enjoyed each for their own beauty, without being repetitive.
Day 3
The day began at the Park HQ. We were told that we might not be able to go on the Long Langsat River Walk that we wanted to, due to a fallen tree. Instead, the staff suggested an alternative. Thinking that it would be the same, we agreed.
We were put on a boat, but this time, we sailed down Sungei Melinau and into the bigger – and a bit rougher – Sungei Tutoh. A pleasant hour-long boat ride and we were brought to Long Iman, another Penan settlement. Pretty similar to the one we visited yesterday, but relatively bigger. We were told the same about the river walk and that, instead, we will take a walk to a waterfall. Our guide came for us a while later; he spoke no English and I almost no Malay.
He began the walk by offering us walking poles, which he cut from the trees on the spot. That should have been a clue to what we were getting ourselves into. This became, by far, the most difficult, strenuous, tiring, and trying walk we undertook on this trip. While there was a path, it was a jungle track on hilly, uneven terrain, with overgrown thorny vegetation along it, crossing slippery logs and into muddy calf-high streams, under the blazing sun and accompanied by numerous insects. The Park HQ staff said it would take an hour; the local guide said 40 minutes; given how unfit I am, it took nearly 90 minutes.
We ended at a waterfall, the Ba’Desai waterfall. While it was not terribly impressive, it was a pretty sight, and relatively untouched, rarely visited, and very serene. After splashing in there for about 15 minutes, it was time for the same arduous walk back along the same way, except that now, closer to noon, it was hotter than before.
This hike will be good if you are into challenging walks. I was not; I wanted a walk in a park to the waterfall … I ended up mud-encrusted, sunburnt, scratched, bitten, and totally exhausted. I was proud that we did it, but it was not something I had planned for or expected. We were so exhausted from this walk that we gave up on our planned afternoon walk, and slept it off in the resort instead.
In all, we had a lot of fun in all the walks that we did while there. While the waterfall walk was not what I expected, it was part of the adventures that come from doing fun things while traveling. I would strongly recommend this place and the tours with the Park HQ, with their pleasant staff; but be aware of what the different routes entail.

Day 1: Mulu Heritage Centre (free); Botanical Trail (free); Night Walk (guided)

Here, i'd like to give a bit of information on how to go about a cost-saving trip to Mulu. First of all,
you need to book your air ticket online . You don't need to go through travel agent which may charge a little bit more for their service. Rather, you can travel on your own or with your friends...here's how you can do it. Contact Mulu National Park at 085-792300/792304. Make room or bed reservation with the staff at the price for a bed without air-conditioning :RM40 (with breakfast) - that's my accomodation when i last visited Mulu. You don't need to worry on transport to your place of stay as there are quite a number of private cars waiting, and you will be charged RM10 to and from the airport (bargain with the drivers) You will be charged for RM10 being entrance fee to the National Park. On arrival at the National park, you can straight away register yourself to visit the 4 caves at RM5 per cave. Somehow, you need to pay extra RM30 being boat fee to go to the clear water and wind caves. The departure time for the caves is as below:
Deer/Lang caves: 2 pm-2.30 pm everyday
Wind/Clear water caves: 8.30 am everyday
So, as far as i am concerned, I think it is not a problem at all to visit Mulu caves yourselves. To the caves lovers, please start your travelling plan ! Cheers and happy vacation at MULU!

To get to Mulu is no longer an issue. If you are going from KL, book the early morning Air Asia flight to Kota Kinabalu and connect with the Maswing noon flight to Mulu via Miri. You leave LCCT at around 8.30am and will be at the Mulu Park HQ by 2.30pm if all go well. Stay for 3 nights and you can get to all the attractions except if you want to go trekking to the Pinnacles, you need to stay away for 2 more nights. So plan accordingly. Well worth the effort I am told. Returning is just retracing the flights, leaving at 3.00pm and you should be back in KL by 9.00pm.
Don't need to spend a bundle to stay at the Royal Mulu Resort. Just stay at the Mulu park HQ. It is convenient because all walks and trek start from here.
It goes without saying the place is full of interesting activities, from leisurely caving, to adventure caving, to long jungle walk, be educated about the rain forest and the limestone formation. And what better way to be introduced to the forest than to go on the canopy walk. All worthwhile activities, not expensive, and generally very well maintained and signposted place. This should be a model for so many other Malaysian wilderness destinations which lack good signage, proper maintenance and cleanliness.

We have just returned from 2 nights at Mulu, having purchased a package deal. On our afternoon arrival at the airport we were met by our guide, Andy, and transferred to our hotel (The Marriott), and then started on our afternoon tour to Lang and Deer caves. We loved the c 3km walk in along well maintained boardwalks through virgin jungle. Both caves were easy to walk through on the walkways and suitably lit (although a torch can be helpful). We were lucky enough to be at the caves late in the afternoon so our group of 4 plus guide were the only ones in each cave, and we left Deer cave as the bats were already departing. We sat for a while at the observation area just watching the twisting ribbon of departing bats in the sky.
The next morning we started early at 8am on a boat trip to Wind and Clearwater caves. The stop at the Penan village was interesting and the information boards and small handicraft market worth seeing. Our early start meant that again we had the caves to ourselves. In my view, Wind cave was the most spectacular, but each of our group had a different favourite!! Then we had time for swimming in the crystal clear but very cold river before lunch provided at the rest area.
The Marriott is a great place to stay if you want a little luxury, and 24 hour electricity with aircon, but prices are high for drinks etc (not surprising given the logistical challenges of being in a place with no road in or out!). There are a few local cafes around, but no real nightlife and most places only have electricity for a few hours each evening (so take a torch in case you need to get up in the night!).
We were very impressed at how well organised and maintained everything is and highly recommend a 2 or 3 night visit here, even though it is not cheap with airfares and package costs.

My visit to Mulu caves was one of the most fascinating in my life. The sheer size of the caves was awesome - my guide said the largest (Sarawak) could easily contain eight Jumbo Jet aircraft nose to tail. Apart from its massive capacity and Guano sodden floors, the rock formation and scurrilous wildlife in the semi darkness was an education in itself. For me, best of all was observing the bats search for food at dusk. As an erstwhile mathematician, I was totally fascinated by the eery three dimensional sinusoidal waves of millions of bats emerging from the Deer cave mouth in search of food. For the first time ever I was able to apply some length of arc calculations, in a useful real context, to help me estimate the number of bats in the air - in millions!. The formation is an incredibly efficient way to ensure that each bat gets an opportunity to eat flying insects without being directly behind a competitor. Even more fascinating is the 'group instinct' to move as if connected together - I didn't see any strays out of formation though there might have been a few outliers (outfliers?) - the sky was filled with their, swirling dipping and diving. This is an experience I would strongly recommend to those who have the energy to walk over, in places, undulating sometimes slippery crumbling earth and rocks. I am still in awe of my experience and I think you will be too.

Is it possible to go by bus from Mulu to Bandar Seri Begawan?
I heard that there is a bus from Mulu to Miri, then BSB. Or from Mulu to Limbang, then BSB.
But I cannot find the bus route with timetable and price on Google.

Hi,
In June I will be in Mulu. I would like to ask if it is possible to do two trips: Deer & Lang Caves and Clearwater Cave & Cave Of The Winds during one day?

It looks like it is possible, as long as you arrange the time accordingly.
Clearwater Cave & Cave of the Winds should be done by 12noon. Then you might have a break for an hour before Deer & Lang Caves at 2pm.

What to wear and now to prepare to go to Mulu caves? Are kids age 5 and 8 ok to go ? Will it be scary?

normal trekking cloth but good to have sandles as u might keep leg in water while river cruise by motor boat. It is safe for kids, my kids were of 3 & 7 when we visited 1st time in 2006. Now much more improved facilities. Not at all scarry, you all might bring home bag full of sweet memories to share. You can check on net on packages available by age group.

Hi, around 30mins flight from Miri by ATR is the best option. By river boat is too long but can try if you enough time & group.

I do get claustrophobic in very tight, airless places. I have been in open caves with no problem. How close a space would you say you found in the caves? Thanks for anything you can advise.

hello.. can anyone recommend the most impressive cave(s) to see in the area? i ve read the best one requires advanced caving experience (don t have that). we don t mind a trek but certainly don t have special caving skills. I m looking for something large, beautiful and spectacular! also what would be the best way to get there from tip of borneo area? thanks so much!

all the caves are spectacular, its a package,you register at the national park n the guide will take you to visit the caves. no experiance needed.the only one that require strenght n extreme climbing is going to the Pinnacles n you can opt out of this. from tip of borneo( sabah) - you have to go back to Kota Kinabalu n take a flight ( via MAS Wings) to MIRI .MULU is in Sarawak.

I am planning a three-day visit with my family to Mulu NP. Is it reasonable/possible to do "Clearwater Cave & Cave of the Winds" tour and "Deer and Lang Caves" tour on the same day? Would it be managable with a 12-year old kid?
