Good spot to stop for the night. Unless you are willing to stay in PEMEX stations, it is the only spot for several hundred kilometres in either direction. Park is very basic but has water, sewer and electricity, and a security guard who stays on site all night. Lots of big trucks jake-braking as they pull into town. Also lots of roosters to wake you in the morning. We have stayed here for 8 seasons going both ways, and will continue to do so. Actual rate is MX$250 pesos. We camped here in a Motorhome.
Long pull-throughs, but tight corners. Hookups were 15-amp connectors on 30-amp breakers. Typical low Mexican water pressure and high voltage. A fine place for an overnight or to leave your rig while you take the Copper Canyon railroad tour. Easy to miss when entering town. As soon as possible, get on the "lateral" roadway on the right, paralleling the main road in to town off the highway. The entrance to the park is very soon after getting on the lateral. A pretty good park for Mexico. We camped here in a Motorhome.
