Safety First—Because Paradise Is Best Enjoyed Responsibly

Whether you’re diving, boating, biking, or just soaking up the tropical sunshine, we care about your safety. These tips will help you enjoy your time here safely and confidently.

On and in the Water:
Boaters should stay aware of shallow areas, travel at safe speeds, especially in channels and harbors. Divers and snorkelers must always display a red-and-white diver down flag to alert boaters, and take all precautions to avoid decompression illness. (If symptoms occur, Keys hospitals are well-equipped to diagnose and treat it.)

On the Road:
Cycling is welcome along U.S. 1, but the paved Overseas Heritage Trail offers a safer, scenic option that parallels the highway in many areas. In Key West, where biking is especially popular, riders must use lights at night.

Under the Sun:
The sunshine at latitude 24° is beautiful—but powerful. Unprotected skin can burn in minutes, so apply sunscreen often and stay hydrated.

Health & Emergency Care:
The Keys have three full-service hospitals, and in serious cases, patients can be airlifted to mainland facilities. Mosquito protection is also recommended for personal comfort and health.

Weather & Safety Updates:
During hurricane season (summer and fall), this website becomes part of the official information network to keep visitors and residents informed about any potential evacuations.

Low Crime, Great Peace of Mind:
Crime is rare in the Keys, but the Monroe County Sheriff’s Office offers helpful advice on how to stay safe and aware.

Decompression Illness

If you suspect decompression illness, seek medical care right away at any Florida Keys hospital. Local hospital staff are experienced in diagnosing and treating dive-related conditions and can arrange transfer if needed. The U.S. military operates a decompression chamber in Key West, and another—more frequently used—facility is located at Mariner’s Hospital in the Upper Keys.

Celebrate The Sun, Protect Your Skin

In the Florida Keys & Key West, the sun puts on a show twice a day. Spectacular sunrises paint the sky in shades of red, pink, and purple, and Key West’s world-famous sunsets are celebrated nightly with music and cheers.

But don’t forget about the hours in between. In our subtropical sunshine, the rays can be strong, reflecting off sand, water, and even clouds. Locals recommend wide-brimmed hats, UV-protective clothing (like UPF 50-rated apparel), and regular use of reef-safe sunscreen to keep your skin happy and your vacation burn-free.

Chill Out Responsibly

You’re welcome to bring coolers and refreshments when visiting our public beaches and parks, just remember, no alcohol, please. The Florida Keys & Key West enforce open container laws that prohibit alcohol on most public beaches, parks, and streets, including the world-famous Duval Street. Keep an eye out for posted signs indicating where alcohol containers aren’t allowed.

Mosquito Protection

Mosquitoes love the tropics too—but a few simple steps can help keep them away. The Aedes aegypti mosquito, common in warm regions like the Florida Keys, can carry mosquito-borne illnesses through the bite of an infected insect. Here’s how to protect yourself and your stay:

  • Use repellent: Choose one with DEET, picaridin, or oil of lemon eucalyptus. Long sleeves and pants add extra protection.
  • Eliminate standing water: Mosquitoes breed in still water—so empty coolers, flower pots, buckets, or anything that might collect rain.
  • Check your screens: Make sure window and door screens fit snugly and don’t have holes or tears.
  • Keep it cool: When possible, use air conditioning to stay comfortable and mosquito-free.
