Entrance to park is very tight for big rigs. We have a 35 foot fifth wheel and crew cab dually pickup and we made it. Sites are all gravel with concrete patios. Electrical is 30amp, with most sites working while we were there with only about 5 other RV's. Restrooms and showers are OK by Mexico standards. The park has the only laundromat in town and it is one of the more expensive places I have ever done laundry. The machines are old and do not wash clothes well and take only tokens sold by the campground. The park is also the site of the major water purification plant so bottled water is easily purchased. It is within easy walking distance of downtown Alamos; 4 blocks. We camped here in a Fifth Wheel.
