Daniel was our guide for a wonderfully serene walk. The trail was an easy distance and mostly shaded, allowing us to enjoy the abundant greenery. Along the way, we spotted sloths, frogs, a snake, and an owl. I even found a not-quite-ripe passion fruit on the ground. Being on this nature-filled trail was a soothing balm to my nervous system. Daniel was amazing—kind and helpful throughout the tour. He assisted us in taking photos of the sloths through his telescope and translated between English and Spanish to ensure everyone felt included. After a strenuous hike up the volcano the day before, this was the perfect, relaxing activity. We never felt pressured to add more to our itinerary when we booked this tour at the front desk. With lovely guides, adorable sloths, and nature galore right off the road, I highly recommend this experience. 10/10!
shaina s. via 🦉 Tripadvisor · July 5, 2024⭐⭐⭐⭐⭐10/10 recommend.
Totally recommended, it is worth paying a little more and going with a small group, in our case just my partner and I (they did not cancel the tour or add us to another group). Very professional. Alan Guevara's guidance was quite an experience, both for his knowledge and for his involvement and protection. Their experience shows, on the morning of the first day we had almost seen the most animals possible. A pleasure!!!
Roberto H. via 🦉 Tripadvisor · April 11, 2024⭐⭐⭐⭐⭐Professional, dedicated and communicative
Beautiful tour, it is a must!! The mangroves and Sierpe river are gorgeous, and the guide is also really good. We could see many animals and really feel in the wild.
