Grassy Key

Local lore has it that this sleepy little key was named not for its vegetation—mostly native trees and shrubs—but for an early settler by the name of Grassy. The key is primarily inhabited by a few families operating small fishing camps and roadside motels. There's no marked definition between it and Marathon, so it feels sort of like a suburb of its much larger neighbor to the south. Grassy Key's sights-to-see tend toward the natural, including a worthwhile dolphin attraction and a small state park.
