This park is located inside the compound for the Serenidad Hotel on the south side of Mulege. It only has 9 sites and only 4 would hold a big rig. The water is DRINKABLE! The electric is 15 amps, but 138 volts, so our surge protector will not let us connect. Sewer hookups at the site. The wonderful thing about this park is you have access to all of the hotel facilities, including the swimming pool, excellent restaurant, and the famous Saturday night pig roast. After a couple of weeks in the local parks, this feels like civilization. They also have a private airstrip if you want to fly in, which many guest do. We camped here in a Motorhome.
