Montoso is one of the most prominent features in the Cerros del Rio volcanic field. At 7315 ft, the peak provides a terrific view of the eastern Pajarito Plateau, including Los Alamos and White Rock. The peak is characterized by a horseshoe shaped ridge that opens to the north. This could very well be the remnants of the  volcanic crater which has been breached on the north by drainage and erosion.

There is no established trail to reach the summit, but a good approach is from the north flank that can be reached via a four wheel drive trail. The trail extends west from the power lines on the east side of the mountain.  From there it is fairly easy to hike to peak. The highest point is indicated by a bench mark from the USGS. There is a plastic canister near the marker with paper and pencil for folks to  record their visits.
