The largest island off the Dry Tortugas is Loggerhead Key. It covers about 49 acres. A lighthouse that was constructed in 1857 is located on this island. We moored on the east side of the island. This was our first-time mooring. We swam to shore then snorkeled on the west side of the island. They refer to this spot that we snorkeled at as Little Africa. There was a house-like structure that was split entirely in half.
It was an amazing snorkeling adventure. The visibility was amazing. It was a unique experience swimming in turquoise water, void of gravity. It felt like we were swimming in a giant aquarium. We saw French Angelfish, and a zillion other species that would take me forever to research what they were. Lovely purple sea fans could be seen everywhere. Truly another world, an alien landscape.
