We highly recommend this company for its professionalism. We will use them again when we return to Cabo. For cruise passengers this is at least a 20-25 min walk from the port to the tour office.

Rosa was a great guide and explained a lot about the dolphins and other species. We saw two different groups of common dolphins and swordfish. They get up really close to the boat. It was a lot of fun and really fascinating to see them up close. This is a very fast boat and the ride can get bumpy. In case you have any back problems, you should reconsider... All in all, I think it took about 3h.”
