Best Beachfront Resorts in Key West
Casa Marina vs Pier House vs Southernmost Beach Resort
True sandy beaches are rare in Key West. The island sits on coral and limestone, so most shoreline is rocky. Fewer than 5 resorts offer true beachfront access — this page compares the top beachfront resorts head-to-head.
The best beachfront resorts in Key West are Casa Marina Key West for the largest private beach, Pier House Resort & Spa for a walkable Old Town beach, and Southernmost Beach Resort for a central location near Duval Street. True sandy beaches are rare in Key West, making these properties stand out.
Why Beaches in Key West Are Rare
Key West sits on a coral reef and limestone foundation. Unlike mainland Florida, the island does not have naturally wide sandy beaches. Most of the shoreline is rocky coral, mangrove, or seawall. The sand you see at resort beaches and public beaches is almost entirely imported.
This makes beachfront resorts genuinely rare and valuable in Key West. Only a handful of properties offer direct beach access, and private beaches are even scarcer. If a beach is important to your trip, choosing the right resort matters more in Key West than almost anywhere else in Florida.
For public beaches, Smathers Beach offers the most sand, while Fort Zachary Taylor State Park has clearer water and better snorkeling. Neither is walkable from most hotels — but the resort beaches listed below are steps from your room.
