Overview

Biscayne is 95% underwater: this is a marine park where the real attraction is beneath the surface. The coral reefs here are the northern edge of the Florida Keys ecosystem, accessible from Miami in 30 minutes but visited by fewer than 600,000 people annually (compare that to Yellowstone's 4 million). The catch: you need a boat. Most of the park's islands and dive sites require your own vessel or a concessionaire tour. If you can't get on the water, you're limited to a small mainland visitor center with minimal trails.
