West Mesa is all the open land west of Rio Rancho, dirt roads, arroyos, with a few scattered houses.. The Puerco is all the open land that drops into canyons and mesas off the west end of the West Mesa, down into the Puerco river Valley..
Of the two areas, the Puerco is more rugged, has sandstone areas, arroyos, mesas, some great sandstone play areas. some roads can be hard. Many places where 4 Low is used.West Mesa is a large mesa, that Rio Rancho is built on, with many old dirt roads, and some arroyos flowing down toward the Rio Grande. More open with views of Sandias. Generally not as hard low range driving. Many open arroyos and wandering around on dirt roads. Both are fun, You chose which one you want to drive on. To get to the Puerco you would be driving on West Mesa roads to get there. Glad you can get out and do some wheeling. Do both rides, that's what I am doing!!
