Lobstering in Miami & Biscayne National Park: Spots, Access & Tips

This is the top of the Florida reef tract, and it might be the most productive lobster water in the state. Biscayne National Park, just south of Miami, protects thousands of patch reefs, a sprawling nursery, and the recruitment pipeline that keeps it all stocked. If you want to understand why a place produces lobster instead of just where to drop, Biscayne is the best classroom in Florida. Here's the biology, the spots, and the one rule that trips up every Miami diver.

Why Biscayne grows so many lobster

Most lobster guides tell you where bugs hide. Biscayne is worth understanding at the source, because three things line up here that don't line up anywhere else.

The Gulf Stream comes close. Spiny lobster don't grow up where you catch them. Adults spawn offshore, and the larvae (phyllosoma) spend the better part of a year drifting in the open ocean on the currents. The Gulf Stream, and its nearshore arm the Florida Current, swings tight to Miami here, so the postlarvae riding it have a short trip to settle onto coastal habitat. Biscayne sits right where that conveyor belt comes ashore.

Biscayne Bay is a protected nursery. When those postlarvae settle, they need shallow, sheltered nursery habitat to grow up in: seagrass, sponge, and hard bottom. Biscayne Bay is exactly that, and a big stretch of it is the permanent Biscayne Bay/Card Sound Lobster Sanctuary, a no-take zone the state established specifically to protect spiny lobster breeding and juvenile grounds. You can't harvest a single bug in the sanctuary, but it works as an engine, growing the lobster that eventually walk out onto the reefs you can dive.

The patch reefs are unmatched. The park preserves the northernmost segment of the Florida reef tract and holds thousands of individual patch reefs, one of the densest concentrations anywhere in Florida's coral reef. More structure means more ledges, more overhangs, and more lobster habitat per square mile than almost any other stretch of the Keys or coast.

Put it together: a steady supply of incoming larvae, a protected nursery to raise them, and an enormous amount of reef for them to spread onto. That's why Biscayne produces year after year.

Where to lobster around Miami and Biscayne

The patch reefs are the whole show, but they aren't the only option.

• The patch reefs (the star). Thousands of them dot the bottom inside Biscayne National Park, scattered across miles of water. That spread is your friend: if one is picked over, idle a few hundred yards and drop on the next. There's no shortage of structure to work.
• Grass ledges and nearshore rocks off Sands Key and Elliott Key. Along the ocean side of these barrier islands, low grass ledges and nearshore rock hold bugs in shallow, beginner-friendly water. A good calm-day option and an easy place to learn.
• Nearshore hardbottom off Key Biscayne. Shallow rock and hardbottom closer to Miami gives newer divers and small boats a manageable target.
• The main reef tract. When it's calm, run out to the deeper reefline for classic reef diving.
• The north end toward Haulover. North Biscayne Bay and the water up toward Haulover Inlet mark the northern edge of this fishery (and the north boundary of Lobsterly's coverage).

Know the closed areas (they're marked in the app)

Biscayne weaves more protected water through its productive water than just about anywhere, so this is the part to get right. Inside the park, you can only take lobster east of the barrier islands during the open season. The entire bay side, from shore out to the islands, is the year-round no-take Biscayne Bay/Card Sound Lobster Sanctuary. On top of that, several specific reef areas are closed to all harvest:

• The five Coral Reef Protection Areas: Fowey Rocks Lighthouse, Alina's Reef, Marker 3 Reef, Lob120 Reef, and Ball Buoy Reef.
• Legare Anchorage, where swimming, snorkeling, and diving are prohibited year-round.

Every one of these closed areas is clearly marked in the Lobsterly app, so you can see exactly where the lines are and stay legal without guessing. The protected water is laced right through the good water here, so check the map before you ever pull a bug.

Getting on the water

The Biscayne reefs are reached by boat, mostly out of the south Miami-Dade ramps:

• Black Point Marina (Cutler Bay) is one of the closest launches to the southern patch reefs.
• Homestead Bayfront Park sits right next to the Biscayne National Park headquarters, with direct access to the southern reefs.
• Matheson Hammock (Coral Gables) and Crandon Park Marina (Key Biscayne) put you on the northern reefs and the Key Biscayne water.

As everywhere, parking and trailer spots are the bottleneck on busy weekends and during the two-day mini-season, so arrive early.

Miami and Biscayne are Lobsterly's Miami & Biscayne region, the northern end of the app's coverage from Haulover Inlet south.

The rule that trips up Miami divers

Here's the one to get right. During the two-day mini-season, the bag limit splits at the Biscayne National Park boundary:

• Miami-Dade waters outside the park: 12 per person, per day.
• Inside Biscayne National Park: 6 per person, per day, the same as Monroe County.

The catch is that most of the famous patch reefs are inside the park, so plenty of divers who think they're on a 12-bug day are actually capped at 6. Know which side of the line you're on. In the regular season (August 6 through March 31), the limit is 6 everywhere.

The rest of the rules are statewide:

• Size: carapace larger than 3 inches, measured in the water. Carry a gauge.
• License plus a spiny lobster permit are both required to harvest.
• Night diving for lobster is allowed in Miami-Dade, including during mini-season (unlike Monroe County), though Biscayne National Park and other areas can set their own conditions, so check before you go.
• No-take zones: the bay-side Biscayne Bay/Card Sound Lobster Sanctuary, the five Coral Reef Protection Areas, and Legare Anchorage (see the closed areas above, all marked in the app).

Stay safe out there

Miami's water is busy, and mini-season turns it into a parking lot of boats. Protect yourself:

• Fly a dive flag and stay near it. Within 300 feet in open water, 100 feet in channels. Boats must slow to idle within 100 yards of a flag.
• Mind the current and the channels. Flow moves hard through the cuts on a tide; plan your drift and pickup.
• Dive with a buddy, track your boat, and watch the weather.

Frequently asked questions

Where can you go lobstering near Miami?

The thousands of patch reefs in Biscayne National Park are the heart of it, some of the densest patch-reef bottom anywhere in the Florida reef tract. Beyond those, work the grass ledges and nearshore rocks off Sands Key and Elliott Key, the deeper main reef tract on calm days, and nearshore hardbottom off Key Biscayne. Stay out of the no-take Biscayne Bay/Card Sound Lobster Sanctuary and the five Coral Reef Protection Areas.

How many lobster can you catch in Miami during mini-season?

It depends which side of the park boundary you're on. During mini-season you can take 12 per person, per day outside Biscayne National Park, but only 6 inside it, the same as Monroe County. Since most of the famous patch reefs are inside the park, most reef divers are at 6. In the regular season it's 6 everywhere.

Why is Biscayne so good for lobster?

Three things stack up: the Gulf Stream runs close and delivers incoming larvae, Biscayne Bay is a protected nursery with a permanent lobster sanctuary, and the park holds one of the densest patch-reef concentrations in the Florida reef tract. More habitat, better supply, more lobster.
