About us

We run high-quality tours of discovery — designed for the adventurous. Expect reef and rainforest exploration that is edifying, exhilarating, and often hands-on.

We are based in Drake Bay, right next to Corcovado National Park, in the heart of one of Costa Rica's most untouched ecological wonders. The Osa Peninsula still holds surprises for anyone who comes to see nature — and the Corcovado area has been called “the most biologically intense place on Earth” by National Geographic.

“I hesitated booking because of the price, but we took the plunge and went for the full experience — and it was incredible! The logistics with Eric were smooth as butter: clear, patient, proactive and extremely responsive. Hands-down the best thing we did in Costa Rica.”

“It was really well organised and they helped with the kids. The private guide meant we could go at our own pace — really necessary with children. Erick was a great guide and communication was easy.”

“We did the two-day, one-night tour in Corcovado with our guide Alejandra. The number and variety of animals we saw exceeded our expectations by far. She explained everything well, was a great spotter and took amazing photos. A once-in-a-lifetime experience we can 100% recommend.”

“You start with a fun boat trip from Drake Bay to Caño Island, then snorkelling at two different spots with the guide — it felt safe and at a good pace, not rushed at all. A superb experience and a must-do.”

“An all-around successful trip — everything was very well organized and the group size of six was very pleasant. Our guide Marlon was very knowledgeable and we saw many different animals. Absolutely recommended!”
