Description
Start by heading uphill on the access trail to the Rainbow Trail #1336: Alvarado Creek to Hermit Pass, and head north until the trail crosses County Road 160, a four wheel road that climbs up to 13,000 ft where it ends on the ridgeline. There are several options to get water at Middle Taylor creek or take a detour to one of the several lakes. At the pass, continue past the boulders halting vehicle traffic, down onto the Rito Alto Trail. Follow the trail clockwise around the bowl, which becomes the North Fork Crestone Trail, ascending the 2nd pass much lower than the first. Again, there is a trail that could take you to the lake if you wanted. After crossing the pass, follow the North Fork Crestone Trail, avoiding turning down to the creek on the San Isabel Trail. The trail crosses several streams which run even during late summer, so there are amble opportunities to get water. Another climb crosses the 3rd pass and down into another valley that would be worth a whole day exploring. At the next trail juncture, stay high onto the Venable Trail which climbs to Venable Pass, the 4th, final, and 2nd highest pass of the loop. After gaining the ridge, stay on the main trail, avoiding the side trails to the Venerable Lake Trail, and descend back to the initial Rainbow Trail intersection with the access trail spur back to the trailhead.
