Same distance as HDT Tested. Nicolas Barth Ryan "Tuna Helper" Weidert September 2013 The Arsenic route is best when combined with the Little Egypt route for a more scenic, diverse and shorter Hayduke Trail. Instead of more of the same in Poison Spring Canyon, turn off up the Aresenic Canyon tributary which features a nice stretch of cottonwoods and beautiful slickrock. A detour up to Arsenic Arch is possible. There are also several technical slot canyons here, which can be walked up to the last obstacle. This route does pass through two short sections of slot canyon with some modest climbing challenges (which can be bypassed if necessary). The lower slot has an 8 ft dryfall to climb (pass packs) or bypass. The upper slot has a 13 ft high dryfall with a chockstone at the top- we found this to be an easy chimney climb (good friction) and passed packs (see bottom right). Some experience chimneying and a length of rope may be handy. From here walk a series of roads to the edge of a bench, then down to Hwy 95. This route leaves the HDT at about Section 4 Mile 29.1 (Mile 183.8) and joins the Little Egypt alternate at Hwy 95, 4.3 road miles south of the HDT. The Arsenic route is 6.9 miles long and is 1.1 miles shorter than the HDT when combined with Little Egypt.
