Changing Tide Tours-Who Are We?
Over 7,500 guests have toured the Golfo Dulce with us during the past eight years. We are proud of the fact that, in addition to being the longest operating tour boat provider on the OSA, we are also known as the ‘Premium Tour’ on the Gulf. That's because our custom-built, deleted 27' tour boats are safe, comfortable and well equipped; and they are always manned by a professional two-man Captain and Guide team.
CHANGING TIDE TOURS IS THE TOP-RATED TOUR BOAT PROVIDER ON THE GOLFE DULCE, PENINSULA DE OSA, COSTA RICA.
Whales, dolphins, manta rays, whale sharks, sea turtles, sharks, schooling fish, and sea birds—all these and more have been seen by our guests.
