Very good - Excellent day. With 1h30 trip for each lAdo. All impeccable. The guide “Nano” explained everything very well. Just emphasize that the bath part has to be evaluated when rains occurred because the river carries a strong current Many thanks

Best tour in La Fortuna with Santiago as a guide! - We had an absolute amazing day with Santiago as our guide and Oliver as our busdriver. Oliver is just so sweet and the nicest person you will ever meet. And then there is Santiago who is the best and most funny guide. He explained us so much in detail about all the animals and insects. We saw 2 sloths. Monkeys, frogs, snakes, scorpion and other insects. We would not have seen these animals if we did the tour on our own. We saw the amazing blue water of rio celeste and had a very delicious lunch, best casero! This tour was the best one we did in La Fortuna! Don’t hesitate and just book it, you won’t regret!

We also spotted lots of animals and learned about plants thank to our guide - we did the tour to Rio Celeste in the rainy season but we were lucky enough to see the blue color anyway. The driver Olivier arrived on time. He was very kind and welcoming, he gave us some information during the hour and a half trip, which made it all more interesting, especially on the way back where he took a secondary road to let us admire the hilly countryside around La Fortuna. The guide Santiago was very knowledgeable, funny and enthusiastic, at the same time extremely attentive to the group. I learned a lot and felt safe. I highly recommend.

Wonderful family hike in Rio Celeste - Santiago and Annie were really wonderful. They took the time to show us and explain as many animals and information as possible! We had the chance to see howler monkeys, capuchins, sloths, snakes, frogs etc. Although there falls was scrambled, we had a patch of blue and the blue lagoon was beautiful!

Great day at Rio Celeste - Awesome day with Santiago and Annie, I would book this activity a thousand times. Access to the waterfall is currently blocked due to a lanslide, but you get close enough to admire the beautiful view. Saw many things, vipers, monkeys, frogs, a scorpion and snakes. Hike is medium difficulty, really not thst bad.

Our guide was amazing.... - Our guide was amazing. She provided a lot of interesting information and pointed out wildlife we never would have seen on our own. Lunch was delicious. Only reason isn’t five stars is because you won’t be able to swim or see the bright colors in the summer. Not their fault but wasn’t like the pictures.
