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.

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

Denise was the perfect host! She was very responsive, easy to work with and everything was as described. Well, it was more beautiful than the photos represent! We enjoyed the site, it was directly on the canal, with easy access for the boat. The kids enjoyed ping-pong, swimming and riding bikes in a secure /safe environment. We'll definitely be back! Thanks Denise!
