Changing Tide Tours-Who Are We?
Over six thousand guests have toured the Golfo Dulce with us during the past six years. We are proud of the fact that, in addition to being the largest tour boat operator on the Osa, we are also the "Premium Tour" on the Gulf. That's because our custom-built, nine-passenger 26' tour boats are new, safe, comfortable, well equiped; and manned by a professional two-man Captain and Guide team. The following is NOT a quote specifically selected from our logbook for its content, it is absolutely an AVERAGE entry: "An unbelievable way to end our trip to Costa Rica, we loved every second, what a wonderful experience!"
Nicole and Brian, New York
Changing Tide Tours is the top rated tour boat provider on the Golfe Dulce, Peninsula de Osa, Costa Rica.
