Late summer is the best time to enjoy this trail up to Pecos Baldy Lake, located at the base of Pecos Baldy Peaks. Park at Jack's Creek Campground ($2 fee) and head on up to Trail 257. This trail takes you through amazing mountain scenery, with wildflowers and shimmering aspens, up to a pristine high alpine lake. Bighorn sheep frequent the area, and have actually been known to be a bit of a nuisance up by the lake. This trail is heavily travelled, so be prepared for fellow hikers, and keep an eye out for afternoon thunderstorms - the terrain is rather exposed. This trail is located in the Pecos Wilderness, so mountain bikes are not allowed.
