Definitely worth while if you're on vacation in the area! Oscar was our guide and he answered all of our questions while out looking for the humpbacks. He introduced us to information about an environment so unique and awe-inspiring. You never know what you'll see and when you'll see it when you're out in the natural world. It was the... More

We have been going out whale watching with Onca for several years and have never been disappointed. Each trip is different, yet exciting. Oscar and Saul have been tracking the whales'migration for about 10 years and know where to find them. This year we even heard a whale "singing." Saul let us listen to the hydrophone. We saw at least... More

We took the Onca Explorations day excursion that goes into the mountains close to Durango, to visit the Tufted Jay Reserve and nearby community of El Palmito. All the details of the trip were as promised, and quite enjoyable. The forest at the reserve was beautiful and the bird life plentiful. We would definitely recommend this trip and have confidence...

I went on this tour as an unenthused tag-along with wifey who wanted to watch humpback whales. Jesus' passion as our guide was contagious, and I had an amazing experience. I came away from the tour sharing this passion. Thank you, Jesus, for the fun-filled adventure! I highly recommend the humpback whale watching attraction, especially during mating season (Dec -...

We managed to organise a last minute dolphin adventure with ONCA and were so pleased we did as it was the highlight of our vacation. Setting off from the yacht club our skipper and Jesus Manuel radioed local fishermen to find where the pods of dolphins were located, speeding over 22 miles offshore and without land in sight we hit...

My wife and I recently went on the two day Birding Sierra Madre tour, and greatly enjoyed our experience. The tour was as described to us with efficient transportation, personable guides and beautiful landscapes. We were able to see the Tufted Jays almost immediately upon arrival, and saw a second group later the same day. We also ended up seeing... More

It was a very active day seeing lots of whales, and the guide was very informative the organization was very thoughtful. We would do it again if we had... More

Oscar was great to work with when I was trying to coordinate a day/time and book the tour. Little hiccup with the boat we were going to go out on but they got a new boat there really fast. We saw some whales, a hammerhead shark, dolphins and sea lions. Great day on the water with a helpful crew and... More

Great Experience. We saw 4 whales on December 30th. They gave us lifejackets, snacks and drinks. Very educational also.
