About Marathon Beach
Marathon sits in the heart of the Middle Florida Keys and is one of the few Keys communities with a true family sand beach — Sombrero Beach — alongside its reputation for fishing, boating, and the local sea-turtle hospital. Warm, clear, shallow water year-round makes it a relaxed, family-friendly base in the island chain. Rip currents are Florida’s deadliest beach hazard, so check the safety flag and rip-current risk above, follow posted flags, and swim near a lifeguard.
