Oscar was a fantastic guide. He is very knowledgeable, very easy to talk with, and he cares about the region's ecology and communities. He took as much time as we needed/wanted to explore the petroglyphs and the beach. A truly unique and amazing learning experience. I definitely recommend this tour if you are interested in anthropology and ecology. Lunch was... More

A unique experience to see aquatic life. First the boat is not big, bring a wind breaker, and make sure you use the bathroom before you leave. We were treated to the sights of dolphins up close to the boat as well as turtles. We also got to here the whales singing under the water, but the best part of... More

We booked 3 days with Onca in early January: Whale & Dolphin Watching; Mangrove Ride; and Bird Watching in the Sierra Madre. Could not have asked for a better time. We saw Sting Rays jumping out of the water, Dolphins, tons on Dolphins, and Whales, more than expected. The birds were unbelievable in the Mangrove. Ate fresh raw oysters that... More

A travelling partner was interested in a whale watching trip, so we went and I am SO GLAD that we did! What an excellent and unique adventure. I typically stay glued to the beach for my entire vacation, and this was definitely worthy of leaving the sand. The guides are very knowledgeable and lots of fun. They mix education with... More

We have been booking with onca for seven years and counting and it is always a top notch experience. Oskar the owner and his dedicated crew do everything to make your trip memorable. As marine biologists they educate as well as entertain guests. I can't say enough good things about this organization. Book with them you won't be disappointed.

Saw way more than expected. Our tour guide Jesus marine biologist was very well versed on marine life and species. Definitely worth booking if whales and dolphins are of interest to you.

We went on the whale watching tour. Our guide, Jesus, was wonderful. He is a marine biologist with a vast knowledge of the whales and other marine life. He explained and taught us throughout the four hour tour. We followed a male and female humpback whale for several miles. We will do this again!
