We booked this tour because it was advertised as a dolphin watching, snorkeling jet ski tour. We arrived at a very nice modern marina and the wave runners were in fairly food condition. When I asked about snorkeling our guide informed us that the visibility was poor amd we wouldn't be able to. Our guide explained the basics and then told us to follow him. The majority of our tour was in the open ocean which was too rough to enjoy. My wife was miserable. Towards the end of the tour he finally brought us to a calm bay but got angry when I tried to take advantage of the calm waters. Another person on the tour asked if we could attempt to snorkel. Although it was murky water it was a nice diversion from the rough open water ride. We did 10 activities in Costa Rica and this was the only disappointment. Save your money and go horseback riding or tour the mangroves.
