So peaceful and beautiful. Nice little beach. Of course there are weeds and some rocks, it is the Keys. But both of these provide a place for the fish and other aquatic creatures to live. We went snorkeling one day and watched the fish swim under us. We also used our paddle boards to enjoy some of the coast line. Jack and his family are friendly and I thank them for sharing their slice of paradise with us. We will be back in January.

Fantastic RV park right on the water. There was a cute little area by the water with lounge chairs and some tables, we sat nearly every night watching boats go by and the sun go down. Directions to get there were very easy to follow, check in was a breeze, the park and facilities were well maintained and clean. Staff were easy to find and helpful.

It doesn’t get any better than this …. at the end of the day a perfect sunset enjoying a fire pit by the beach enjoying cup of wine 🍷

No screen enclosure permitted.

This fire-pit grill is a common area share by all.

This property was very peaceful and calming. I was able to put my kayak on the private beach and go out at my leisure. Fish on the private dock. And my campsite was rather private with nice lights and a beautiful fire ring. I also felt secure with the closed gate. I couldn't have asked for a better getaway.

Weekend Trip to Kings Kamp RV Park and Marina

I am an eagle scout and I've been camping many places but so far I believe that this has the most bang for your buck. Amazing bathrooms, nice beach, smooth roads, nice lots. Close to john pennekamp state park and close to a publix for supplies. It was my first time in the keys but it won't be my last. I did have a bit of a hard time with a hammock especially since I like to cool down outside of the tent but most lots from what I have seen had atleast a couple trees and I was able to tie up to my truck bed for my hammock. Keep in mind there are some street lights at night that illuminate the road but may keep you up if you need total darkness, but otherwise wonderful spot. Close to the cut and early morning fishing yields results there

What a beautiful place to stay, and right on the water. We were next to the marina and got to see all sorts of cool fish and sea life. The bathrooms are very nice and facilities are well kept. Thank you!
