OWD cert dives in 2008. Cavern cert dives in 2009. Perfect location for both. Viz is unlimited. Water level was high 2nd time & a manatee swam into the area of the where people swim, snorkel & do OWD cert dives - very cool. Please don't go into the cavern unless you're trained to do so. Lack of training is the #1 cause for cavern/cave accidents - not worth it - don't be tempted.
