RV camping at John Pennekamp Coral Reef State Park

Reviewed by Ben Kiser, RV rental operator and fleet consultant.

42 sites with full hookups, and two official figures for how long an RV can be: the park page says most sites take 40 ft, the reservation system lists 62.

Outdoorsy day rates on October 8, 2026. Across the Keys set the median is $165.

Still choosing the RV? Start with the RVs that reach Key Largo. The three Keys state parks that take RVs share one set of stay and booking rules, laid out in renting an RV for a Keys state park.

RVs that fit Pennekamp

Two tests, both from published figures. The host’s delivery range has to reach the campground in a straight line from where the RV is kept, and the listed length has to clear the campground’s own cap. Outdoorsy does not say whether its range is road miles, so confirm the drop with the host.

The park page: "Most sites can accommodate an RV length of 40 feet; a few sites can accommodate a few feet longer." The Florida State Parks reservation system shows "Max trailer length 62". The filter uses the park page, because the site you are given is what has to fit.

Listed right now: 79 listings on Outdoorsy with a host delivery range that reaches Pennekamp campground. 78 of them are 40 ft or shorter. 1 is longer and left out. This is the live set, so it moves through the day and can differ from the measured count above.

Towable or motorhome, by the numbers

From the same pull of the RVs listed within 100 miles of Marathon, joined to each host’s delivery range. Across the Keys set a travel trailer’s median day rate is $110 and a Class C’s is $256.

How the RV gets here

Almost every RV for the Keys is kept in Miami or Homestead and comes down US-1. Only 2 of the 144 listed within 100 miles of Marathon are based in the Keys. So the question is whose delivery reaches this campground, and whether the campground lets a delivered RV in. Card Sound Road tolls by axle and the delivery fees hosts publish are on the trip cost page and the delivery page.

The rules, in the source’s own words

Quoted, because a paraphrase of a limit is how a foot goes missing.

Rule

Every Florida state park

14 nights per stay, 56 nights per six months

The maximum length of stay that one may have for a single reservation is 14 nights total ... you may not reserve more than 56 nights in the same park within a six-month period.

The campgrounds, as each one publishes them

Where a cell reads not published, the campground’s own pages are silent on it. The office number is the place to ask.

  • Pennekamp campground. Most sites 40 ft per the park page; the reservation system lists a park maximum trailer length of 62.

Where the official numbers disagree

Both sides are printed. Neither is averaged, and neither is dropped.

Longest RV the campground takes

  1. Most sites 40 ft, a few a little longer

A 42 ft rig can be bookable in the reservation system and still not suit most of the sites. The site you are assigned is what has to fit.

What no official page answers

Each of these was looked for and not found. Ask the office before you book around it.

  • Whether the campground has a dump station: not stated on the park pages read. Every site has sewer.
  • Which sites take more than 40 ft: the park says a few do and does not name them.
  • Delivered rentals: no Florida State Parks rule addresses a host dropping off an RV.
  • Construction since July 22, 2026 has reduced boat trailer parking and closed one ramp and the boat pump-out. The park does not say when it ends.

The other Keys campgrounds

Middle Keys

Curry Hammock State Park

What decides it here

The easiest state park in the Keys for a big rig: 70 ft maximum, 28 gravel sites with 50 amp and water, and a dump station. The catch is the 14-night cap and the three nights out after it, which a delivered trailer cannot do on its own.

Bahia Honda State Park

What decides it here

Three loops, three different answers. Buttonwood takes large RVs, Sandspur stops at 23 ft hitch to bumper, and Bayside sits behind a bridge with 6 ft 8 in of clearance.

What decides it here

Long Key takes no RVs. Its campground is hike-in tent sites with no hookups, so an RV booked for Long Key has nowhere to park.

What decides it here

Jolly Roger is the only campground in the Keys that says it works with companies that deliver and set up rented RVs. Grassy Key turns away anyone arriving after 4:30 p.m.

Key West RV parks

What decides it here

Three parks, three different catches. Boyd's takes 45 ft only in select sites and sets a four-night minimum over Fantasy Fest and the holidays. Leo's stops at 42 ft counting bumpers and bike racks. Bluewater turns away late arrivals and bans driving the RV once you're in.
