Shark Valley is a 15-mile paved loop trail in Everglades National Park off of Highway 41.
At the halfway point is the Shark Valley Observation Tower. Cool views from the top. We saw enormous gators below that have lived there for years, eagles soaring, and a view of the Everglades for miles in every direction.
The second half of the loop had less wildlife, but was still a nice bike ride. At the end of the loop we walked along the Bobcat Boardwalk, which is a boardwalk trail going through a hammock. We also walked along the Borrow Pit Trail (accessible from the main paved loop) until this guy blocked the path.
Otter caves along the hammock trail- basically solution holes along the limestone path.
We were fortunate or unfortunate enough to come across a dead alligator floating upside down in the water. The ranger told us that he died of natural causes and had been floating there filling with gas for several days. Because he was so bloated his weiner was alert and saluting us. We were told that they were waiting for the gator to pop, at which point the vultures would swoop in and have a feast. Some real circle of life shit.
