About Key Biscayne Beach
Key Biscayne is an island community just south of Miami, reached by causeway and bracketed by two natural parks — Crandon Park and Bill Baggs Cape Florida State Park at its southern tip. Its calm, shallow, warm Atlantic water and quieter beaches make it a favorite family escape from the city. The water stays warm nearly year-round. 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.
