Los Lomitas Trail in South Mountain Preserve is the connector trail between the middle of the developed picnic lands and the giant parking lot that separates the conference center from the group picnic grounds. It is the third and final leg of my South Mountain Infrastructure Loop.
For all that, this trail is worth doing on its own. Because this is part of the loop, we start in the middle of the park, and head towards the great lot where you likely left your car.
We start at the four-way junction: The Bajada Trail goes south, up the slope. The Ranger trail continues South, towards the Five Tables Trailhead. The Derby Trail, which is oft signed as part of Los Lomitas, goes west to eventually join the Max Delta Trail, but the part we want, the main portion of Los Lomitas, heads east, before bending north.
East now, from the junction, Los Lomitas goes over low hill and shallow wash a few times before crossing some flat desert. On the far side of that, you reach Los Lomitas Cabanas, which were fenced off when I was there, but the restroom was open. By open, I mean unlocked. The gate door is closed and latched, presumably to keep the critters out of the garbage. Latch it back up behind you.
The trail follows ridgeline NE to the Kiwanis TH (and another RR), then parallels the road a spell before dropping into a large wash near the ramada compound of the Piedras Grandes picnic grounds.
The trail follows the wash for some distance. Here, you trudge through sand, as opposed to the packed dirt of the trail that came before. In mid-day, the high walls of this wash present your only hope for shade. Los Lomitas climbs out of this wash to merge with Box Canyon Trail, a horse trench bending more north now. Soon, Box Canyon/Los Lomitas parallels the Judith Tunell accessible trail as it gradually bends from north to northeast before reaching the parking lot.
Where exactly in the parking lot depends upon where they are in the endless construction. This flat expanse of asphalt hides few secrets, and rarely more than a dozen cars. You’ll be fine.
Are We Lost Yet?
