No public access for the Cañoncito and Bart's Trailheads
Mike Coltrin's Sandia Mountain Hiking Guide notes that as of 2001, the road to the Cañoncito and Bart's trailheads was closed to vehicle traffic but that "The private
landowners currently allow hikers to walk up the road to the trailhead." No longer. Instead, the private land is posted, and the fine print makes it clear that there's no exception for people on
foot. At this time, sadly, the closest access points for the Cañoncito Trail and Bart's Trail are via the Cienega Canyon picnic area and the south end of the Crest Trail.
