Vault Mine Trail One Hundred Forty is a 2.5 mile moderately trafficked out and back trail located near Sonoita, Arizona that features beautiful wild flowers and is rated as difficult. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible year-round.
This is not rated but I would recommend difficult. Elevation gain is nearly 2000' in just 1 mile and top altitude is 7400'. Not an easy stretch. We combined with Agua Caliente, Josephine's saddle and Super trail for a nice 8 mile loop. Once you get to the top great views. Overall great hike. We hiked in late march and there was still some snow on upper trail.
