Snorkel next to a Tropical Wildlife Mangrove Island on the shallow lagoon-style Florida Bay side of Key Largo. This is a Birding Rookery on top of the ‘Trees that Walk on Water’ the Red Mangrove with roots that build islands. When they can’t touch the seabed in 18″, they are colonized by marine life of all kinds including colorful sponges. Snorkeling is fun!
