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

My wife and I have been thinking of a whale watching tour for a while. When the opportunity happened, we went with ONCA while in Mazatlán,we were so glad we did. 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.

We booked a whale watching tour for Dec 29th. All info was done by email so we were a bit leary. We were given our confirmation and a pickup time at our hotel. The lift came right on time. We got to the marina and were separated into groups by weight and size. Very safe. Everyone got life jackets before... More

Our family has been to Mazatlan multiple times since 2008, since then we have travelled a lot within the city and done many tours but I must say this is one of the best ones we have been on so far! Coming in to this tour we didn't have much for expectations other then we wanted to see Humpback Whales!... More

We were picked up at our hotel by Oscar, owner, guide, interpreter, and knowledgeable naturalist. Transportation up the Durango Highway was delightful and beautiful. A light breakfast and coffee at overlook of a huge canyon hit the spot before a little 4-wheeling to take a great hike looking for birds, especially the Tufted Jay and Red Warbler two endemics to...
