Cunningham Falls State Park MD
Camp next to the president. This park is located next to Camp David where the POTUS used to go for vacations to give there security detail a break unlike our current president who just keeps wasting our tax money flying down to Florida every weekend. Ok enough ranting.......
Great campsite, with a small lake with beach the kids can swim at. Only thing is there is a steep hike back and forth from campsite to beach, we ended up driving to beach area after our first attempt to walk to beach with all our gear, as an excuse we did have a 7 year old with us.
Great easy loop hikes around campsite with a decent waterfall depending on when it last rained. Great local get away only 1 hr away from DC.
