The trail head is a simple indistinct opening in a fence line along the side of the road. From there the trail is relatively well marked to the top of the nearby peak. The view from above is worth the climb which took about 30 minutes. If you continue along the trail to complete the loop, you will be mostly bushwhacking as the remainder of the trail from the peak is almost indistinguishable. However, it is during this second portion of the hike that petroglyphs are visible in the canyon beside the stream. It was a fun and adventurous hike. For a more tamed version, climb to the top of the peak, take in the views, and climb back down the way you came in.
Think we did the La Cienega trail instead of the La cienguilla trail with the petroglyphs, it was ok.
