Southeast of Sedona off Schnebly Hill, the newer Hangover Trail runs above the parallel Munds Wagon Trail through the locally known Cow Pies slickrock. The Hangover Trail is accessed off the upper eastern end of Schnebly Hill Road and flows westward. There are a few newer, informal trails that depart from the Hangover Trail and head north up into the redrock formations, but these are exceptionally challenging routes. The trail is intermittently marked by white painted blazes directly on the slickrock surface. The Hangover Trails western end descends back down to catch the last mile or so of the Munds Wagon Trail skipping the rockiest sections.
To reach the mountain biking trailhead for the Hangover Trail from uptown Sedona, head west on SR89A to SR179. Then follow SR179 south 0.3 miles. Turn left heading east on Schnebly Hill Road for 0.8 miles. The route starts at the signed parking area on the left. From the trailhead parking area, head east 4 miles on Schnebly Hill Road ascending 1,100 feet.
Tip: The Hangover Trail is a hardcore mountain bike ride for experienced riders only. Make sure to only attempt on warm, sunny days to avoid mud and ice. There are numerous cliff side sections where the penalty for error is extreme. Hiking is recommended in these areas. Considering that there are also several very steep sections, you can expect the Hangover Trail to be a sketchy hike-a-bike experience.
