RV Parks In Marathon, Florida

24.7138° N, 81.0904° W

Quick Overview

Marathon sits in the heart of the Middle Keys, roughly MM 47 to 60 along the Overseas Highway, and it is one of the most rewarding (and pricey) RV destinations in Florida. This is camping on the water, with ocean and gulfside sites, world-class snorkeling and fishing at your door, and the iconic Seven Mile Bridge just to the south. The catch is that the Keys are reservation-driven and often sold out, so planning is everything.

The public-versus-private mix is excellent but expensive. The public anchor in town is Curry Hammock State Park at MM 56, with spacious concrete-pad sites, ocean access, and water/electric hookups, one of the only state-park campgrounds in the Middle Keys. About 20 minutes south, Bahia Honda State Park at MM 37 has world-famous Keys beaches and water/electric sites, and ranks among the hardest reservations in the country. Both state parks are moderate-priced and book the instant the 11-month window opens.

On the private side, the waterfront parks command premium Keys rates but put you right on the water. Jolly Roger Travel Park at MM 59 is a 160-site gulfside park with full hookups and dockage, Grassy Key RV Park & Resort has 38 oceanfront sites, each with its own tiki hut, a heated pool, and a fishing pier, and Sunshine Key RV Resort & Marina near Big Pine is a full-amenity island resort. Big rigs do best at the private resorts and Curry Hammock; Bahia Honda has older, length-limited sites. Because US-1 is the only road through the Keys, plan your fuel, groceries, and water before heading down-island, and watch the tropics through hurricane season since the highway is the only way out. Run a 50-amp site so you can keep the air conditioning going in the heat and humidity. The sections below cover how far ahead to book each park, what a site costs by season, the public-versus-private trade-offs, and which campground fits the kind of trip you have in mind.

Traveling to Marathon by RV

There is one road to Marathon: US-1, the Overseas Highway, which runs the length of the Keys with mile markers used as addresses. Marathon spans roughly MM 47 to 60. The highway is flat and big-rig friendly but slow and busy with limited passing, so allow extra time and patience. The single bigger concern is resupply, since fuel, groceries, and water options thin between towns and Keys prices are real, so stock up before you head down-island rather than counting on a store down the road.

Marathon has a small airport, but for major airports and big-box services your best bets are Key West about 50 minutes south or Miami about 2 hours north. Once you are set up, everything is a short hop along US-1: Sombrero Beach in town, the Seven Mile Bridge and Pigeon Key just south, the Turtle Hospital and Dolphin Research Center nearby, and Bahia Honda State Park about 20 minutes down-island. Leave the rig at camp and use a tow vehicle for day trips along the highway.

Before You Go: RV Trip Essentials

Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Marathon, Florida, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.

Check your RV insurance coverage

A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.

Know your roadside assistance options

RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.

Decide about an extended warranty early

Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.

Set up a travel rewards card for fuel and fees

A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Marathon

The Keys are pricey, but the cost still splits by ownership. The two Florida State Parks (Curry Hammock and Bahia Honda) sit in the moderate band, the best value down here for water-and-electric sites right on the water, which is exactly why they sell out the instant the window opens. The private waterfront resorts command premium Keys rates: Jolly Roger, Grassy Key, and Sunshine Key all run at the top of the price scale for their oceanfront and gulfside full-hookup sites with tiki huts, dockage, heated pools, and marinas.

Timing drives price as much as the park. Winter snowbird season pushes rates to their peak with the tightest availability; summer and fall are cheaper and more open if you can take the heat and watch the tropics. Budget travelers should target the state parks (book them the day the window opens) or visit in summer or fall for lower rates. Beyond the site fee, factor in Keys prices on groceries and fuel, which run higher than the mainland, and stock up before heading down-island.

Best Time to Visit Marathon by RV

❄️

Winter

Nov - Feb

67F - 77F

Crowds: High

Snowbird peak with warm, dry weather and the best water clarity. The Florida State Parks (Curry Hammock, Bahia Honda) book the instant the 11-month window opens, and private waterfront sites go months ahead. This is the most expensive and hardest time to land a spot, so plan well in advance.

🌸

Spring

Mar - May

72F - 82F

Crowds: High

Warm and dry with great snorkeling visibility, but spring break and lingering snowbirds keep it busy and pricey. Book Curry Hammock and the private parks ahead for any weekend. Comfortable camping weather with light bugs, before the summer humidity and storm season set in.

☀️

Summer

Jun - Aug

78F - 89F

Crowds: Medium

Hot, humid, and buggy with afternoon thunderstorms, but rates drop and the parks open up. Hurricane season runs June through November, so watch the tropics. Run a 50-amp site for the AC and bring bug protection. The quieter, cheaper season if you can take the heat.

🍂

Fall

Sep - Oct

74F - 83F

Crowds: Low

The quietest and cheapest stretch, but peak hurricane risk, especially September and October. Watch the tropics closely and have a plan to leave, since US-1 is the only road out. If the weather cooperates, you get the Keys nearly to yourself at off-season rates.

Explore the Marathon Area

A few things we have learned camping around Marathon. Set a reminder and book the Florida State Parks (Curry Hammock and Bahia Honda) the morning the 11-month window opens; they sell out instantly, and Bahia Honda is one of the hardest reservations in the country. If you cannot land a state-park site, the private waterfront parks (Jolly Roger, Grassy Key, Sunshine Key) are your full-hookup fallback, but reserve those months ahead for winter too.

Avoid hurricane season if you can, especially September and October, or watch the tropical forecast closely and have a plan to head north early, since US-1 is the only road out. And stock up on groceries, water, and fuel before heading down-island; the Keys prices and the gaps between stores are real, and you do not want to make a special trip back up the highway for supplies. Run a 50-amp site so you can keep the AC going in the heat and humidity.

Frequently Asked Questions About Dump Stations in Marathon

What are the best RV parks in Marathon, FL?

In Marathon itself, Curry Hammock State Park at MM 56 is the public standout, with spacious concrete-pad sites, ocean access, and water/electric hookups, one of the few state-park campgrounds in the Keys. For private full-hookup waterfront, Jolly Roger Travel Park at MM 59 has 160 gulfside sites with dockage, and Grassy Key RV Park & Resort on Grassy Key has 38 oceanfront sites, each with a tiki hut. Just south, Bahia Honda State Park (about 20 minutes) has world-famous beaches, and Sunshine Key RV Resort & Marina is a full-amenity island resort near Big Pine.

Do Marathon RV parks have full hookups?

The private parks do. Jolly Roger Travel Park, Grassy Key RV Park & Resort, and Sunshine Key RV Resort all offer full hookups, with waterfront sites and amenities like dockage, heated pools, and marinas. The two Florida State Parks are the exception: Curry Hammock has water and electric with a central dump station but no sewer at the site, and Bahia Honda is water and electric (up to 50-amp on some sites) with a dump station and no individual sewer. In the Keys heat you want the full hookups, so the private parks are the move if running the AC on a 50-amp service matters.

How much does RV camping cost in Marathon?

The Keys are pricey, but it splits by ownership. The Florida State Parks (Curry Hammock and Bahia Honda) sit in the moderate band, the best value down here for water-and-electric sites on the water, which is exactly why they are so hard to book. The private waterfront resorts command premium Keys rates: Jolly Roger, Grassy Key, and Sunshine Key all run at the top of the price scale for their oceanfront and gulfside full-hookup sites with tiki huts, dockage, and marinas. Winter snowbird season pushes rates to their peak; summer and fall are cheaper. Expect Keys prices on groceries and fuel too.

How far ahead do I need to reserve a campsite in Marathon?

As far ahead as you possibly can. The Florida State Parks (Curry Hammock and Bahia Honda) open an 11-month reservation window, and they sell out the instant it opens, especially for winter dates. Set a reminder and book the morning your dates release. The private waterfront resorts (Jolly Roger, Grassy Key, Sunshine Key) book months ahead for the winter season too. There is essentially no first-come availability in season; the Keys are reservation-driven and often sold out. Summer and fall are easier, but even then the best waterfront sites move early. This is the toughest reservation market on this list.

When is the best time to go RV camping in Marathon?

Winter and spring have the best weather, warm, dry, and clear, which is exactly why they are the busiest and priciest, with the state parks booking the day the window opens. If you can plan 11 months out, winter is the classic Keys camping season. Summer is hot, humid, and buggy with afternoon storms but cheaper and more open, fine if you have a 50-amp AC site. Fall is the quietest and cheapest but carries peak hurricane risk in September and October. For the best balance, target late spring or be ready to book winter very early.

Can big rigs camp in Marathon?

Some can, but it takes care. The private resorts are the most big-rig-friendly: Jolly Roger has waterfront full-hookup sites that handle larger rigs, and Sunshine Key RV Resort has big-rig resort sites. Curry Hammock has spacious concrete pads that work for many larger rigs, though it is mixed, so confirm. Bahia Honda is the tough one: its older sites have length limits and it is hard to book at any size. Grassy Key is a small park, so check your length. US-1 itself is flat and big-rig friendly, just slow and busy, so plan your fuel and groceries since options thin between towns.

Why is Bahia Honda so hard to book?

Bahia Honda State Park, about 20 minutes south of Marathon at MM 37, has some of the most famous beaches in the Florida Keys, and that combination of world-class sand, snorkeling, and a limited number of waterfront state-park sites makes it one of the hardest reservations in the entire country. The 11-month window opens and the sites are gone almost instantly. The campground's older sites also have length limits that shrink the pool of available big-rig spots further. If Bahia Honda is full, Curry Hammock in Marathon is the more available state-park alternative, and the private parks fill the gap.

What public-land camping is there around Marathon?

Two Florida State Parks anchor the public camping. Curry Hammock State Park sits right in Marathon at MM 56 on the oceanside, with spacious concrete-pad sites, ocean access, hammock posts, and water/electric hookups, one of the only state-park campgrounds in the Middle Keys. About 20 minutes south, Bahia Honda State Park at MM 37 has world-famous Keys beaches and water/electric sites (some up to 50-amp). Both book through Florida State Parks on the 11-month window and sell out fast. There is no real first-come or dispersed camping in the Keys; it is a reservation-driven, often sold-out market.

What is there to do in Marathon besides camp?

A lot of water and wildlife. Sombrero Beach is a free, palm-lined city beach, one of the best in the Keys. Just south, the iconic Seven Mile Bridge runs to historic Pigeon Key, and Bahia Honda State Park has famous beaches and snorkeling. In town, the Turtle Hospital rehabilitates sea turtles with tours, and the Dolphin Research Center on nearby Grassy Key runs education and interaction programs. The reef offers world-class snorkeling and diving, and the flats, reef, and offshore waters make Marathon a serious fishing destination. Paddling and boating round out a trip built around the water.

Are Marathon campgrounds open year-round?

Yes. Curry Hammock, Bahia Honda, Jolly Roger, Grassy Key RV Park, and Sunshine Key all operate year-round, with winter as the clear peak. What changes is demand and price: winter is snowbird peak with warm, dry weather and instant sellouts, spring stays busy with break crowds, summer is hot, humid, and buggy but cheaper and more open, and fall is the quietest and cheapest with the highest hurricane risk. Because nothing closes for a season, your planning challenge is landing a reservation and timing the weather, not finding an open gate, especially in the November-to-April peak.

Should I worry about hurricanes camping in Marathon?

Yes, plan for it. Hurricane season runs June through November, with September and October the highest-risk months in the Keys. Because US-1, the Overseas Highway, is the only road in and out, an evacuation means a slow, single-route drive north, so you cannot wait until the last minute. If you camp the Keys in late summer or fall, watch the tropical forecast closely and have a clear plan to break camp and head north well ahead of any system. Winter and spring are outside the season and the safest windows. Do not get caught down-island with a storm tracking in.

How do I get to Marathon with an RV?

There is exactly one road: US-1, the Overseas Highway, which runs the length of the Keys with mile markers (MM) used as addresses. Marathon runs roughly MM 47 to 60.

Can I camp on the water in Marathon?

Yes, that is the whole appeal. Curry Hammock State Park at MM 56 has ocean access right from the campground. On the private side, Jolly Roger Travel Park sits gulfside at MM 59 with waterfront sites and dockage, and Grassy Key RV Park & Resort has 38 oceanfront sites, each with its own tiki hut, plus a heated pool and fishing pier. Just south, Bahia Honda State Park puts you near some of the best beaches in the Keys, and Sunshine Key RV Resort is a full-amenity island resort with a marina. Waterfront is the norm here, which is part of why it commands premium rates.
