“Miller was kind, insightful and extremely thorough. He is passionate about nature… We would recommend this trip to anyone.”

“Our guide, Jonathan, was amazing. I don’t know how he spotted so many birds, insects, crabs, and even 2 crocodiles — and he knew all their names in Spanish and English. Then Jonathan gave a Howler call and the leader of the group howled back!”

“Our family of 7, ages 18 to 60, had an amazing day with Miller. The highlight was finding a baby sloth who had ventured away from its mother. After that we had the most delicious traditional lunch in a non-touristy restaurant.”

“Our guide and driver for the day was Eithel, and we couldn’t have asked for anyone better. He took us to the waterfall first rather than last — it was quiet and we had the place almost to ourselves. A real magical green paradise.”

“Our guide located sloths, poisonous snakes, howler monkeys and toucans, and took fantastic pictures with our iPhones by positioning them against his binoculars — our photos look like professional close-ups. A fantastic day.”
