Wonderful State Park, with decent RV facilities fairly close to the water (but no waterviews). Lovely kayaking trails through the mangroves, and a terrific experience snorkeling off the only natural coral reef in the continental US. There's also beach snorkeling, where you can see a sunken Spanish ship and its cannons less than 50 feet offshore.
We were prepared to dry camp here, and were pleasantly surprised to learn that the campground had recently upgraded some sites with electric (50 and 30 amp). We brought our own water, and didn't dump on site, though there are dump stations. (Potable water as well). We had been to the Everglades before--but just on the edges. This campground is 50 plus miles inside the park, right on the Florida Bay. Camping was first come, first served, and we were a little nervous about that, but I guess this is the off-season, since only 4 RVs shared a huge site. The RV area is about a mile from the marina and visitor's center, and we easily biked that distance many times. We highly recommend renting a boat and touring the canals and large lakes nearby this amazing national park. A park ranger warned us about the mosquitos at dusk, but I didn't take her seriously enough. My son and I did some evening fishing, and were mauled by the little guys. I probably had a hundred or so bites. Take plenty of repellant! (Bugs were not an issue during the day, or night--just dusk.) If you want a wonderful experience deep inside one of America's natural wonders, this is the park for you. Nighttime, under the stars with absolutely zero light pollution, was unforgettable. By the way, we had full bars with our AT&T phones, something we don't get at home. There's a cell tower at the Visitor's Center.
We read the reviews here and were a little nervous about this park, but am happy to say we had a wonderful time at Boyds, and stayed four nights with our two teenagers. The park is expensive, but so is everything in Key West, and for what you get, the cost is very reasonable. Friends of ours stayed at a hotel for nearly $400 a night a week before we arrived, and they didn't have an ocean view. The park has narrow spaces and is crowded, but so is everything in Key West. We had no problems getting into our site, and neither did the Class A next door. We loved our site (#123), and enjoyed gorgeous sunrises over the bay every day. Our neighbors were wonderful and the staff was pleasant. Our son enjoyed fishing from the docks in the morning and evening. Our daughter thought the pool was great. We even attended the wedding of two neighbors who got married on their site. We don't carry a toad, and the bus service didn't meet our needs--it does come every 90 minutes, and can take 45 minutes to take you the 5 miles into town--so we rented a car from Enterprise, who picked us up at Boyds. The cost was about $200 for three days, and gave us plenty of flexibility to explore Key West (and enjoy the spectacular sunsets!) You can also rent electric carts, delivered to the campground. We found this option to be more expensive. We will definitely come back to this campground.
We're relatively new to RVing, so our range of comparisons is limited. But we found this to be an excellent facility for our needs. We arrived late on Friday, and requested a waterfront site, which we received. The park was full by the morning, with the annual Chincoteague Oyster festival that weekend. Our site was grass and dirt, nicely level, and with a spectacular view of the bay. The owners were pleasant, the store decent (a little understocked at the end of the season, but 30% discounts on almost everything but food), and the other campers helpful and informative. I do wish that Tom's Cove would allow online reservations and accept credit cards, but the process of sending a deposit check wasn't bad, and neither was paying cash on check in. However, not being able to reserve a site, or be guaranteed a waterfront location in advance, would leave too much to chance if you really must have a waterfront spot. Tom's Cove is a little out of the way--a couple of miles to town. We don't carry a toad, but were able to use the town trolley service, which operates seasonally (and for major events like the Oyster Festival) to get around--there's a stop at the entrance to Tom's Cove. Our kids were able to easily bike to mini-golf and other attractions. Scooter and electric car rental places are plentiful. We found plenty to do on site--fishing, kayaking (we brought our own), star gazing, and generally lazing around. There are bugs--but that goes with the waterfront territory in Chincoteague. We met several families who have been coming to Tom's Cove for years, and we could see why. We will return again the Spring.
