Firstly, we substituted out the ziplining for extra hiking through the forest as I had a sore back that I didn't want to risk ziplining so my review is for everything else on the trip itinerary. Rebecca Adventure Travel were great with being flexible about changing the trip itinerary to suit what we wanted to do. I also found contacting them via WhatsApp and email to be easy leading up to the trip.
Our guide Fausto picked us up on time in a clean and well maintained vehicle. He was very friendly, knowledgeable and very enthusiastic which made for a great day, and his English was fine. We firstly went to a garden to do some birdwatching - saw lots of tanagers and hummingbirds up close and got some great photos, I would highly recommend this if you are interested in wildlife. We then went to Mindo for a chocolate brownie and coffee - both excellent. Afterwards we went hiking in the cloud forest (normally this is when the ziplining would occur), saw some great scenery and waterfalls. The hiking was low intensity but had some hills and slippery sections so would best be enjoyed if you had good boots and a moderate level of fitness. Lunch back in Mindo followed at a local restaurant and was was the traditional 3-course style (soup, main and dessert).
After lunch we went to the butterfly farm - plenty of nice butterflies however if there was anything on the tour that I would skip it would be this, only because lots of the butterflies could also be seen in the forest for free. Our final stop was the Equator Museum which was enjoyable for the short time we spent there, they do some demonstrations which are good fun.
Overall I would highly recommend this tour if you enjoy wildlife and sightseeing, for us it was a great way to spend a free day in Ecuador.
