With about 22 miles of Atlantic shoreline, plus rivers, inlets, and the sparkling Indian River Lagoon, it’s a dream for boaters, beach lovers, and anyone who wants their weekends outside.
Anchored by charming communities like Stuart (the Sailfish Capital of the World), Jensen Beach, Palm City, Hobe Sound, and Port Salerno, Martin County blends laid-back waterfront living with a surprisingly lively food, arts, and local shop scene. You get nature preserves, tons of parks, and that “flip-flops welcome” vibe, without giving up convenience.
