Grassy Key RV Park & Resort

Overview

A small, meticulously kept waterfront RV park at mile marker 58.7, this is a sweet base for exploring the Middle Keys. It’s purpose-built for big rigs and self‑contained RVs, with full hookups and a calm, grown‑up vibe.

Sites & amenities

Expect full hookups (30/50A, water, sewer) and cable at all sites, plus Wi‑Fi hotspots (strongest around the clubhouse). Choose from waterfront, premium, or standard sites; every site has a picnic table. The pool is crystal‑clear and both heated and chilled, there’s a tidy white‑sand lounging beach, and a tiki hut for shade. You also get an air‑conditioned laundry, a clubhouse with seasonal activities, and on‑site boat dockage with a kayak/paddleboard launch that puts you straight onto the Gulf for an easy hop toward the Atlantic.

What it’s like

Clean, quiet, and friendly. Grounds are well manicured and the marina area is the social heart—great for sunrise coffee and sunset colors. Wildlife shows up: guests occasionally spot manatees by the dock and the odd iguana sunning nearby. Cell service is generally strong, and several reviewers report streaming without issues.

Tradeoffs to know

There’s no public bathhouse or showers; plan to use your own rig’s facilities. Some sites near Highway 1 pick up road noise, while waterfront pads are quieter. The beach is mainly for lounging, and swimming can be limited; policies (like no fishing from the dock) have been mentioned by past guests—verify current rules. No‑see‑ums can spike at dawn and dusk, so bring real repellent. One guest noted the pool closed at dusk.

Location perks

You’re steps from the Dolphin Research Center and a short drive to Aquarium Encounters, groceries, and Marathon dining. It’s central enough that day trips up to Key Largo or down to Big Pine and beyond are easy.

Best time to visit

Sunset is the money hour—head to the marina or waterfront pads for the show. Early mornings are best for calm paddling before winds and boat traffic pick up. If bugs love you, avoid lingering outside at dusk.

Who will love it

RVers who want a spotless, small, waterfront base with easy Gulf access and a resort‑style pool. If you rely on campground bathrooms or need lots of grassy space for pets, this won’t be your favorite fit.
