Trail Overview
Rock Block Passthrough is mellow, with only one obstacle being a wash crossing with a steep entrance and exit. The south end of the trail is blocked by large rocks, placed in the trail to deter further progress. On the north end, the trail has been reclaimed by nature, but it intersects with another trail that could be your exit if you choose. Erosion packs the trail, so this isn't a speed run, but it is quite lovely driving toward the mountains. There's a large campsite toward the north end next to a large outcropping of interesting rocks. There are two bars of service (Verizon) but they go in and out, so offline maps are advised. This route is on Arizona State Trust Land. This land requires a yearly permit that can be purchased and printed online. The permits allow certain recreational activities, including camping, bicycling, bird watching, GPS-based recreational activities (geocaching), hiking, horseback riding, off-highway vehicle (OHV) usage, photography, picnicking, and sightseeing.
Difficulty
This trail is unmaintained, so it may prove challenging after rain or snow. The majority of this trail is mellow, but the main wash crossing may be hazardous after a moisture event.
