Below the Surface: Exploring Biscayne National Park’s Coral, Keys, and Quiet Waterways
A shallow-water national park where reefs, keys, and mangroves demand a slower kind of exploration.
I step off the skiff and into water the color of old glass—clear, cool, and alive. The hull slips back into the wake with a soft sigh and the motor’s talk fades until all that remains is the hush of a sea that seems intent on being discovered. Around me, shoals of small fish scatter like coins; farther out, the reef drops away into a blue I can’t name. This is Biscayne National Park, a place where the city’s skyline is a distant memory and the ocean insists on being the main character.
Trail Wisdom
Use mooring buoys
Anchoring damages coral—ask your charter operator to tie to a mooring buoy or use the designated mooring areas.
Bring reef-safe sunscreen
Chemical sunscreens harm coral; use mineral-based SPF and cover up during peak sun hours.
Hydrate and shade up
South Florida heat and sun are intense—carry extra water and a hat for the boat or beach.
Respect nesting season
Keep distance from shorebirds and nesting sites on keys, especially in spring and early summer.

Conservation Note
The park emphasizes reef protection through mooring buoys, visitor education, and partnerships that reduce anchor damage and promote reef-safe practices.
Biscayne became a national park in 1980 to protect its unique combination of offshore reefs, islands, and cultural artifacts, including historic shipwrecks.
Seasonal Guide
spring
Best for: calmer seas, good visibility for snorkeling, birdwatching on keys
Challenges: occasional cold fronts, crowds during spring break
Spring brings warming water and generally calm conditions, but watch for weekend crowds and spring breakers.
summer
Best for: warmest water, long daylight hours, tropical marine life activity
Challenges: high heat and humidity, afternoon thunderstorms, hurricane season begins in June
Summer is hot and lively underwater but also storm-prone—check forecasts and plan early starts.
fall
Best for: fewer crowds, warmer ocean temps, good fishing
Challenges: hurricane season continues through November, variable weather
Fall can be rewarding with warm seas and quieter keys, but stay alert to storm systems.
winter
Best for: clear skies, lower humidity, best visibility
Challenges: cooler nights on islands, shorter days
Winter is the park’s high season—dry, clear, and excellent for boating and snorkeling.
Photographer's Notes
What to Bring
Snorkel mask and finsEssential
A well-fitting mask and fins make reef time more comfortable and productive.
Reef-safe sunscreen and sun shirtEssential
Protects skin and the reef—use mineral SPF and a long-sleeve rash guard for sun and jellyfish protection.
Dry bag (20–30L)Essential
Keeps phones, cameras, and layers dry during boat trips and paddles.
Water bottle with filter or 1.5L+ capacity
Hydration is critical in heat; filter bottles are useful for multi-day trips.
Common Questions
Do I need a permit to camp on Biscayne’s islands?
Yes—backcountry camping requires a free permit from the National Park Service; campsites are primitive and have rules about fires and waste.
Can I snorkel the coral reefs without scuba certification?
Yes—many of Biscayne’s reefs are shallow and accessible to snorkelers; guided trips are recommended for safety and interpretation.
Where do boats and charters launch for Biscayne trips?
Are there shark risks while swimming?
Shark encounters are rare; common sense—avoid swimming at dawn/dusk, don’t bring fish or bait near swimmers—greatly reduces risk.
Is fishing allowed in the park?
Yes, but regulations apply—check federal and Florida state rules for catch limits and protected species, and use designated fishing areas.
How protected are the reefs from anchors and boat damage?
The park enforces no-anchoring zones and promotes mooring buoys to protect corals; operators are generally trained to follow these rules.
What to Pack
Mask and fins for reef exploration, reef-safe sunscreen and hat for sun protection, dry bag to keep gear dry, refillable water bottle to prevent dehydration.
Did You Know
Biscayne National Park is approximately 95% water, protecting mangrove estuaries, coral reefs, and islands rather than large stretches of land.
Quick Travel Tips
Book charters in advance during winter, bring cash for small marina fees, confirm mooring buoy availability, layer with a light windbreaker for boat spray.
Local Flavor
Local operators are often family-run Miami businesses—pair a park trip with Cuban-influenced seafood in Homestead or a ceviche lunch on Key Biscayne to taste the region.
Logistics Snapshot
Launch points: Convoy Point/Homestead; permits: required for backcountry camping; cell service: limited offshore; best time: Dec–Apr; book guides in advance.
Sustainability Note
Use reef-safe products, avoid touching coral, follow no-anchoring rules, and support operators that contribute to local conservation programs.
