Biscayne National Park Guide: Best Activities, When to Visit & Where to Stay

Biscayne National Park is 95 percent water. That single fact defines everything about this park -- how you experience it, how you get around it, and why most people who live within an hour of it have never visited. Located just south of Miami, Biscayne protects 173,000 acres of Biscayne Bay, mangrove shoreline, the northernmost Florida Keys, and a portion of the world's third-largest barrier reef. There are no roads into the park's interior, no scenic drives, and no trails you can walk to from a parking lot. To see Biscayne, you must get on the water.

What awaits is extraordinary. The bay's shallow, clear waters support vast seagrass meadows that serve as nurseries for fish, lobster, and shrimp. The mangrove shoreline -- one of the longest stretches of undeveloped mangrove coast on Florida's east coast -- shelters manatees, crocodiles, and hundreds of species of wading birds. The keys, low-lying islands of fossilized coral, harbor tropical hardwood hammocks and remnants of early 20th-century homesteading. And the reef itself, lying in crystal-clear water 6 to 60 feet deep, supports over 500 species of fish, hard and soft corals, sea turtles, nurse sharks, and the occasional dolphin. Biscayne is not a park you hike through. It is a park you float above.

Best Activities

Snorkeling the Reef -- The park's coral reefs are the main attraction and among the most accessible reef snorkeling in the continental United States. The park concessioner operates guided snorkel trips (approximately $50-$70 per person) that depart from the Dante Fascell Visitor Center at Convoy Point. Popular reef sites include the shallow patch reefs near Elliott Key and the outer reef line. Expect to see parrotfish, angelfish, yellowtail snapper, sea fans, brain corals, and if you are fortunate, sea turtles. Visibility typically ranges from 20 to 60 feet depending on conditions. The trips run about 3 hours.

Scuba Diving -- For certified divers, the reef offers deeper exploration. The park contains six documented shipwrecks along the Maritime Heritage Trail, ranging from a 19th-century schooner to a 20th-century tugboat. Each wreck has an underwater interpretive guide. The most popular dive site, the Mandalay, is a two-masted schooner that sank in 1966 and now rests in about 12 feet of water, making it accessible to both snorkelers and divers. The concessioner and private dive operators in the Homestead area offer dive trips.

Kayaking and Paddleboarding -- The calm, shallow waters of Biscayne Bay are ideal for kayaking and stand-up paddleboarding. A popular route follows the mangrove shoreline from Convoy Point south along the coast, where you can paddle through mangrove channels and spot wading birds, manatees, and juvenile sharks. Longer paddling trips to Elliott Key (about 7 miles each way) are possible for experienced paddlers in calm conditions, but the open-water crossing can be challenging when winds pick up. Kayak rentals are available through the park concessioner.

Glass-Bottom Boat Tour -- For those who prefer to stay dry, the park concessioner operates glass-bottom boat tours over the reef. The 3-hour tour cruises over the coral reefs while a naturalist narrates the marine life visible through the glass hull. The tours depart from the visitor center and cost approximately $40-$55 per person. They operate on a seasonal schedule -- check availability in advance.

Elliott Key -- The largest island in the park and the only one with developed facilities, Elliott Key is accessible by private boat or the park concessioner's boat service. The island has a harbor, a campground, restrooms, cold showers, hiking trails, and a swimming area. The 7-mile-long island is rimmed by coral rock and offers a Spite Highway -- a crude road bulldozed through the tropical hardwood hammock in the 1960s by developers opposed to the park's creation, now slowly being reclaimed by the forest. The island is a good base for snorkeling, fishing, and exploration.

Boca Chita Key -- The most popular island destination, Boca Chita features a picturesque ornamental lighthouse built by a former owner (it was never an official navigational aid), picnic areas, a campground, and a harbor. The island is accessible by private boat or occasional concessioner service. The lighthouse and the island's history as a private retreat make it a pleasant day-trip destination.

When to Visit

December-April -- The dry season is the best time to visit. Temperatures are warm (75-85 degrees), humidity is lower, seas are generally calmer, and visibility for snorkeling and diving is at its best. This is also the peak season for migratory birds. Mosquitoes are less troublesome during the dry months.

May-June -- The transition to the wet season. Temperatures climb into the high 80s and 90s, and afternoon thunderstorms become more frequent. Water visibility remains good in the morning before storms churn things up. Lobster mini-season (last consecutive Wednesday and Thursday of July) draws heavy boat traffic.

July-October -- The wet season brings daily thunderstorms, high humidity, and the risk of tropical storms and hurricanes. The bay can be rough, and snorkel and dive trips are more frequently cancelled. Mosquitoes on the islands are fierce, especially after rains. This is the least popular time to visit, but marine life is abundant and the park is uncrowded.

November -- A transitional month as dry season conditions return. The weather is increasingly pleasant, seas calm, and the park begins to see more visitors. Water temperatures remain warm enough for comfortable snorkeling (mid-70s).

Where to Stay

Camping -- Elliott Key and Boca Chita Key both have waterfront campgrounds accessible only by boat. Sites are $25 per night (plus a $25 overnight docking fee at Boca Chita). The campgrounds have picnic tables, grills, and restrooms but no freshwater or supplies. Bring everything you need. The camping experience -- sleeping on a tropical island with the reef a short swim away -- is memorable.

Homestead -- The nearest town, about 10-15 minutes from the Convoy Point Visitor Center. Homestead has a good selection of budget and mid-range hotels, restaurants, and a Walmart for supplies. Rates start around $80-$150 per night. Homestead is also the gateway to Everglades National Park, making it a good base for visiting both parks.

Florida City -- Adjacent to Homestead, Florida City offers similar lodging options and is the last stop on the Turnpike before the Keys. Several chain hotels are clustered near the intersection of US 1 and the Florida Turnpike.

Miami -- The park is only about 30-45 minutes from downtown Miami, making it feasible as a day trip from the city. The full range of Miami's hotels, restaurants, and nightlife is available, though expect to budget for higher lodging costs.

Key Largo -- About 30 minutes south of the park on US 1, Key Largo is the gateway to the Florida Keys and offers a wide range of lodging options from budget motels to upscale resorts. John Pennekamp Coral Reef State Park, which adjoins Biscayne on the south, offers additional snorkeling and diving opportunities.

Getting There

By Air -- Miami International Airport (MIA) is approximately 35 miles and 45 minutes from the park's Convoy Point Visitor Center. Fort Lauderdale-Hollywood International Airport (FLL) is about 55 miles and an hour away.

By Car -- From Miami, take the Florida Turnpike south (Homestead Extension) to Speedway Boulevard (SW 137th Avenue), then follow signs to the park. From US 1 in Homestead, turn east on SW 328th Street (North Canal Drive) and follow it to the visitor center. The drive from downtown Miami takes about 45 minutes.

By Boat -- Most of the park is accessible only by boat. Private boats can dock at Elliott Key, Boca Chita Key, and Adams Key. The visitor center at Convoy Point has a launch ramp for trailered boats. There is no bridge to any of the islands.

Park Concessioner -- The authorized park concessioner operates snorkel trips, glass-bottom boat tours, kayak rentals, and occasional island transport from the Convoy Point Visitor Center. Reservations are strongly recommended, especially during the dry season.

Essential Tips

Boat safety -- Biscayne Bay is shallow, with extensive seagrass flats, and the water can turn choppy quickly when afternoon sea breezes or thunderstorms develop. If paddling to the islands, check weather and wind conditions, carry a marine radio or fully charged phone, and wear a life jacket. The open-water crossing to Elliott Key can be dangerous in strong winds.

Reef protection -- Do not touch, stand on, or collect coral. Reef damage from physical contact is a serious concern. Wear reef-safe sunscreen (avoid oxybenzone and octinoxate) and consider wearing a rash guard to reduce sunscreen use entirely.

Mosquitoes -- The islands, particularly during the wet season, can have extraordinary mosquito populations. Bring strong insect repellent (DEET-based recommended) and consider long sleeves and pants if camping on the keys.

No freshwater on islands -- There is no drinkable water on any of the park's islands. Bring all the water you need, including extra in case of an unexpected overnight stay.

Fishing regulations -- Fishing is allowed in the park but is subject to Florida state regulations, bag limits, and seasonal closures. Spearfishing is prohibited. A Florida saltwater fishing license is required.

Nearby Attractions

Everglades National Park -- Just 30 minutes west of Homestead, the Everglades offer an entirely different ecosystem -- sawgrass prairies, cypress swamps, and mangrove estuaries. The combination of Biscayne and Everglades gives you a remarkable range of South Florida habitats in a single trip.

John Pennekamp Coral Reef State Park -- Adjacent to Biscayne on the south side, this was the first undersea park in the United States. It offers snorkel and dive trips, glass-bottom boat tours, kayaking, and the famous underwater Christ of the Abyss statue.

Coral Castle -- A curious roadside attraction in Homestead built single-handedly by a Latvian immigrant from 1923 to 1951 using massive coral rock blocks. How he moved stones weighing up to 30 tons by himself remains a subject of speculation.

Fruit and Spice Park -- A 37-acre botanical garden in Homestead featuring over 500 varieties of tropical fruits, spices, and nuts from around the world. Guided tram tours and fruit tastings are available.
