This was quite a great experience as I am relatively new to these waters. Taking entry where the kayaks launch, I snorkeled across to the monument and back - a long swim. I saw turtles and a big eel and loads of great corral and colorful reef fish. On the way back I swam straight out from the monument. I was surprised at how quickly the bottom disappeared, even with an amazing visibility. While in deeper water I came head to head with a large Barracuda which gave me a yawn and showed a very impressive set of teeth. He remained very curious for awhile and certainly did not seem shy or intimidated by our encounter. Heading for the shallows, the reef was a welcome site and there was much to see in 10-20 foot depths.
