No direct public access for the Cañoncito and Bart's Trailheads
The original (2005) edition of Mike Coltrin's Sandia Mountain Hiking Guide noted 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." As the new (2019) edition acknowledges, this access option no longer exists. Instead, the private
land is posted, and the fine print makes it clear that there's no exception for people on foot.
