Tripadvisor’s approach to reviews
Before posting, each Tripadvisor review goes through an automated tracking system, which collects information, answering the following questions: how, what, where and when. If the system detects something that potentially contradicts our community guidelines, the review is not published.
When the system detects a problem, a review may be automatically rejected, sent to the reviewer for validation, or manually reviewed by our team of content specialists, who work 24/7 to maintain the quality of the reviews on our site.
Our team checks each review posted on the site disputed by our community as not meeting our community guidelines.

30 minutes cycle ride from town. Best place to chill in blue waters. Have fun . Caves nearby a bonus. Do visit. I shall again

Well done Judocarli!
Feb. 2023 • Couples
Well done Judocarli! That’s the way to raise intrepid kids! We followed your advice and hired the head torches from the stall at the foot of the steep scramble “path” to the cave entrance. Very glad we had them. Otherwise pitch black beyond the first huge chamber and the picturesque Buddhist shrine. Phone torches completely inadequate. Like you we followed the sometimes difficult to find arrows to the far end of the mind-bogglingly huge cave (at least twice the volume of St Paul’s Cathedral in London). We too had a bit of a melt-down when we couldn’t find the next one on the return route. Unlike your wife, we still couldn’t find it after a few minutes searching, but luckily we managed to improvise and find an eventual link to the entry route. More arrows would have been welcome. Other caves have better formations, but this one is mightily impressive simply on account of its huge scale. Blue Lagoon 1 was busy, commercialised, and great fun. Lots of people, but still plenty of room for a refreshing swim.

CAVERN AND LAGOON
Jan. 2023 • Solo
Not spectacular as to the cave. The cavern and lagoon complex made my visit interesting. There were several people here, including a family with children.

Get the head torch and follow the arrows
Apr. 2021 • Family
Felt a great sense of achievement making it through the whole cave and we really felt like we had it all to ourselves. We all hired flashlights which was a must. It’s not an easy path for three small kids 4, 5 & 7 and definitely some slippery spots and potential steep falls, but they made it to the end with no mishaps and only one small meltdown when mum went off searching for the next arrow we couldn’t find :)
Blue lagoon was quite full the day we were there (pimai) and mostly loaded up with people in life vests. We thought it was quite cold (and the kids weren’t a fan of the fish) so the kids just loaded up their water pistols and shot bystanders. Good fun, but we went back to the hotel for a swim in the warmer waters.

Proper Flashlight and Footwear required
Dec. 2019
Four of us started ... only two of us made it to the end !

The cave entrance is up a fairly steep path ... and once you get inside it's seriously slippy - flip flops probably aren't a good idea !

Once you get deeper inside it gets seriously dark ... a little torch probably isn't a good idea (hire one at the start of the path to the cave entrance).

The cave itself isn't that big, or that stunning - but it's great to be able to wander around on your own.

Afterwards we had a nice soak in the pools, and enjoyed watching the crazy diving antics!

Large cave and lagoon
Feb. 2020 • Couples
One needs to arrange transport to get to this cave. There is an entrance fee and they also have a small fee for a flashlight. The cave is large. However, not as large as the caves in Central Vietnam. One needs to hike up many steps before reaching the entrance to the cave. Might not be convenient for elderly folks.It has a decent amount of lighting. However, one needs to be careful while exploring different areas of the cave as there are steep climbs and dangerous slopes.

The lagoon was clean and looked very inviting for those who wanted to have some fun jumping into the cool and clear refreshing water.

Get the flash light
Mar. 2020 • Couples
The cave is a nice hike and it’s cool.
Pay the 10,000 kip and use their flash flight it makes a huge difference. There are spray planted arrows to follow which makes it easier but once you hit the end the rocks are a bit slippery on the way back.

The lagoon is nice, but very busy. The restaurants around it are expensive. The better priced out of the two is on the far side by the cave entrance.

So quiet
Mar. 2020 • Couples
Well we heard this was a tourist trap however due to corona virus the day we visited we were the only two in the blue lagoon and the cave. We hired a buggy and drove our selves there, you pay a small fee to enter and a small fee for head torch! The climb up to the cave is quite steep, the cave itself is huge and you can explore without a guide. The lagoon was beautiful especially as we had it all to ourself
