This was a really excellent trip, which I highly recommend to anyone who would like to see turtles while snorkeling in Oahu! The trip goes to Turtle Canyon, which is roughly off-shore of Waikiki. The ratio of crew members to tourists who were snorkeling was quite high, which was a helpful feature. I swam most of the way out to the Turtle Canyon, but was assisted by one of the crew members with a raft, to go the final distance. I saw three turtles in a very short time. My daughter, who snorkeled for longer, saw many more, five in one group, for in another, and then some individual turtles or pairs. The trip out to the Canyon and back was also very pleasant.
