Follow the directions for Teocalli Mountain Trail.
When you get near the top of the ridge you'll take a right onto Teocalli Ridge Trail. After a short downhill you'll be in for some more climbing.
After awhile you'll come to a nice view point and stopping area, with great views of Teocalli Mountain, Castle Peak, Pearl Pass, and the Middle Brush Creek drainage on your left. This is a good place for lunch.
The trail continues along Teocalli Ridge and then begins a gradual downhill at first with fun roots/rocks. Eventually the trail comes to several switchbacks reminiscent of the Deadman Gulch switchbacks. Be careful here as some of the switchbacks and the trail itself comes very close to the steep mountainside. A fall here is definitely not recommended. Since the new re-route/downhill changes by the forest service, the downhill is much more sustainable. Many of the very steep/technical spots have been taken out which makes this more of an intermediate trail now.
Eventually the trail opens up into a fast flowy meadow and dumps you back out onto Brush Creek Road/Pearl Pass. Take a right here and follow the road back to the standard parking area.
