A little further north is Big Cypress National Reserve. Biscayne is less than an hour from Miami, Florida.

There are almost 50 keys in the park, most of which are small and undeveloped.

Food options are extremely limited in the park. You will want to bring your own food and snacks. Store food properly and clean up after yourself. It is also never a good idea to feed wild animals at the park.

Park Maps

It is always a good idea to bring a map with you when you’re out adventuring at a park. This is especially true if you plan on exploring the keys and islands on your own. A tide chart and compass are also good to have.

Water Shoes

Swimming, snorkeling, kayaking, and having fun on the beaches is a big part of the fun at Biscayne National Park. You’ll want to protect your feet from sharp rocks, broken shells, floating timber and other marine debris. Sturdy water shoes with hard soles are recommended.

The sun shines all year long at Biscayne. You’ll need to come prepared to protect yourself from harmful UV rays. Always wear sunscreen and reapply often. Use SPF 35+ or higher. Waterproof is certainly a plus. You should also wear sunglasses and a wide-brimmed hat.

Bathing Suit/Wetsuit

Bring your swimsuit so you can get in the water! The beaches, reefs, and bay are excellent places to take a dip in the ocean, especially during the summer when the water is warmer. In the winter you might consider wearing an insulating wetsuit instead.


There are some sights you’ll need binoculars to fully enjoy. Birding is a popular pass time at the park, binoculars help you get a good look at elusive birds from a distance. You’ll also be able to catch a better glimpse of lighthouses and Stiltsville.


Don’t forget to bring your camera! Biscayne National Park is one of the most beautiful places in the country, especially around sunrise and sunset. Capture memories to last a lifetime with your camera. You can even find waterproof cameras to take on tours or snorkeling!
