The BEST campground in the Keys, by far, is Bahia Honda State Park. In 1992, the Bahia Honda beach was selected as one of the 10 best beaches in America. Really great swimming, snorkling and fishing. You can also rent sea kayaks. They no longer rent bicycles, as they says in their ads, but if you bring bicycles, it is a great place to ride. During the summer, you can see turtle nests on the beaches. And the campsites are much better than you will find anywhere else in the Keys. Probably the most interesting sites are right on the water, where you can fish or snorkle from your site, but you will not have as much protection from the sun, because these waterfront sites are not well sheltered by trees. The sites that are set back from the water have many more trees and other vegitation to protect you from the sun. If you are in a tent, there are areas set aside solely for tenters. RV sites have electric and water, but no sewer. Of course there is a dump station. Bahia Honda is only about 40 minutes (approximately 30 miles) from Key West, so it is easy to visit on a day trip. However, the Bahia Honda campground is always filled, so you should try to make reservations as soon as possible through reserveamerica.com. You can make reservations up to 11 months in advance. The maximum stay is 2 weeks. Another option is the cabins, also available through the Bahia Honda State Park, which rent at $130 per day. I think there are only six cabins. We've tried the private campgrounds in the Keys, including the one in Key West, but Bahia Honda is the best. It is also the least expensive, at about $25 per night, as compared with $75 per night in the private campgrounds. Enjoy planning for your vacation!
