Campsites at Elliott Key Campground (2026 Guide)
Elliott Key campground is only reachable by boat, which filters out everyone who isn't committed to the logistics. That alone separates it from nearly every other campground in the National Park System. You cannot drive here, you cannot walk here, and you will not find a bridge, ferry, or shuttle. Your own vessel - or a friend with one - is the only way in.

Getting to Elliott Key Campground
The access situation is straightforward but unforgiving. You need a boat with enough draft to clear roughly 2½ feet of water at the marina entrance at low tide. That number matters. A lot of first-time boaters show up with a vessel that draws three feet and discover the hard way that the channel simply will not accommodate them. Check tide charts before you leave. The marina entrance is the bottleneck.
Once you are tied up, the campground sits within walking distance of the dock. Twenty tent-only sites are available, all of them on an island with zero vehicle traffic. No RVs, no campers, no cars. You carry everything you need from the boat to your site.
The park service recommends downloading the Recreation.gov app before you arrive. Payment for both camping and docking is handled through that app on site. There is no ranger station taking credit cards or cash at the dock.
Site Layout and Amenities
The twenty sites split between waterside positions and spots set back into the partial forest cover. Neither category is bad, but they serve different purposes. Waterside sites catch whatever breeze the bay offers, which matters in the humid months. The forested sites provide more shade and a bit more shelter from wind.
Each site comes with a picnic table and a grill. That is the standard setup, and it works fine for cooking. The restroom building has sinks and cold-water showers. No hot water here, so plan accordingly. The cold showers are refreshing in July and bracing in January.
Docking fees run $25.00 from Friday through Monday and on federal holidays. Camping costs $35.00 per night, which includes boat docking. If you want tenting only without keeping a boat in the harbor, the rate drops to $25.00 per night. Any vessel still in the harbor after 5 PM counts as an overnight stay, and you will be charged accordingly. The tenting fee covers up to six people and two tents per site.
Seniors with a valid America the Beautiful Senior Pass get 50 percent off those fees.
What the Park Website Does Not Mention About the Bugs
The official materials mention insects in a general way. What they do not tell you is that the mosquito and no-see-um pressure on Elliott Key can range from moderate to genuinely unpleasant depending on the season and wind conditions. Early morning is your best bet for comfortable time outside. By late afternoon on a calm day, the biting insects can make cooking dinner an exercise in suffering.
Bring a head net. Bring DEET or picaridin. Bring a tent with intact mesh. This is not a suggestion.
The same conditions that make the island appealing - warm water, humidity, vegetation - also make it prime insect habitat. Most visitors underestimate how aggressive the bugs can be in the summer months. Winter is better, but not bug-free.
Trails on the Island
The campground serves as the trailhead for two walking routes.
A mile-long loop trail starts near the campground and stays manageable for most fitness levels. The surface is flat, the path is clear, and it gives you a solid sense of the island's interior without requiring a half-day commitment. Good option for an after-dinner walk if the bugs are not too bad.
The other trail is the "Spite Highway," which runs roughly six miles down the center of the island. The name alone is worth the walk. This trail is straight, flat, and long. It follows the alignment of a road that was planned but never completed - hence the spite. You can hike the full length or turn around whenever you feel like it. Pack extra water for this stretch. There are no water sources along the trail, and the Florida sun does not care about your hiking plans.
The trail narrows here and there where vegetation encroaches, but it remains passable. The surface is compacted limestone and sand. Not technical terrain, but the distance adds up.
Boater Awareness and Navigation
The park service has issued a caution notice about navigational markers in the waters around Elliott Key. Markers may be missing or have shifted position due to storms, currents, or simple wear. Relying entirely on buoy placement without cross-referencing charts or GPS is a bad idea.
Experienced boaters already know this. If you are new to navigating Biscayne Bay, take the warning seriously. The water is shallow in many areas outside the marked channels, and running aground on a falling tide is a common mistake. The park service recommends using caution in all park waters.
Timing Your Visit
The campground is open 24 hours a day once you arrive, but the window for getting there is limited by daylight and tides. Most boaters aim to arrive well before sunset. Setting up a tent in the dark on an island with no artificial lighting is not a pleasant experience.
The Convoy Point grounds - the mainland side of the park - open at 7 AM and close at 5:30 PM. If you are using a ride share service to reach your boat launch, make sure the service can pick you up before closing time. Getting stranded at a locked gate is a recurring theme in park ranger stories.
What to Bring
Everything. There is no camp store on Elliott Key. There is no concession stand, no vending machine, no one selling ice or firewood or forgotten toothpaste. Whatever you do not bring, you do not have.
Essentials checklist:- Water. Enough for drinking, cooking, and washing. Figure a gallon per person per day minimum.
- Ice in a quality cooler. No resupply available.
- Food that does not require refrigeration after the ice melts.
- First aid kit. Minor cuts and scrapes happen. Medical help is a boat ride away.
- Sun protection. Hat, sunscreen, long sleeves. The reflection off the water amplifies exposure.
- Insect protection. Head net, repellent, after-bite treatment.
- Headlamp or flashlight. The island gets dark. True dark.
- Trash bags. Pack out everything you bring. Leave no trace.
- Phone with the Recreation.gov app installed and payment method loaded. Cell service drops out at various points in the bay, so handle payment before you lose signal.
The Experience
Elliott Key campground is not for everyone. The access requirements alone ensure that only a fraction of park visitors ever see it. If you are looking for a drive-up campground with full hookups and a camp store, this is not your place.
If you want quiet, isolation, and the sensation of being on an island in a national park with no crowds and no vehicle noise, this campground delivers. The water access means you share the space with other boaters, but the number of sites is small enough that it rarely feels crowded.
The Spite Highway is worth hiking at least a portion of, even if you do not do the full twelve-mile round trip. The vegetation changes subtly as you move inland, and the silence away from the waterfront is noticeable.
Practical Takeaways
Plan your boat access carefully. The marina entrance at low tide is only 2½ feet deep. Know your vessel's draft before you commit to the trip. Pay on the Recreation.gov app. No on-site payment options exist. Handle this before you lose cell signal. Book ahead during peak season. The twenty sites fill up, especially on holiday weekends and during winter when the weather is mild. Walk-up availability is unreliable. Pack for self-sufficiency. Water, food, first aid, insect protection, sun protection. There is nothing for sale on the island. Check tide charts. Both for the marina entrance and for any planned excursions around the key. Respect the no-trace policy. Pack out everything. The island ecosystem is fragile, and the park service has limited capacity for waste management.Final Thoughts
Elliott Key campground occupies a specific niche in the National Park System. It is not the easiest campground to reach, and it is not the most amenity-rich. What it offers is access to a side of Biscayne National Park that most visitors never experience - quiet, remote, and genuinely island-based. If you have the boat and the preparation, it is worth the trip. If you are missing either one, the mainland campgrounds at Convoy Point are easier and require less planning.
Rangers will tell you that the visitors who enjoy Elliott Key most are the ones who arrive prepared. That means knowing the tide schedule, having all your gear packed before you launch, and understanding that you are on your own once you leave the dock. Get those pieces right, and the campground delivers exactly what it promises: a night on an island in a national park, with nothing between you and the water but a tent screen.
