This is the only Recreational Vehicle Park in Valencia County, the La Mirada in Belen. There are other places in the county where you can park an RV, but those are generally for long term residents, with a minimum stay of a month. You can always park overnight in either of the 2 Wal-Mart stores, one each in Belen and Los Lunas. La Mirada is large and roomy, easy to maneuver any size RV, 5th wheel or motorhome. Having lived several years in a 5th wheel and traveling tens of thousands of miles in it I know how important it is to have a lot of space. Unfortunately, La Mirada does not have concrete pads, just gravel. However there is very little rain here, so the ground is generally firm and mud is not a problem.
To reach the La Mirada (if you are traveling on I-25), take the middle Belen exit (Exit # 191, NM Route 548) and turn west. Go about a quarter mile to the La Mirada. The entrance is well marked.
