getting there

Drive SR-410 to Bumping River Road (Forest Road 1800). Turn south onto Bumping River Road and continue to Deep Creek Road (Forest Road 1808). At the the sign for the Mount Aix trailhead, turn left onto a short, rough dirt road that leads to a few parking spots and the trailhead signboard and register (3,700 ft). Alternately, park on the right side of the road, across from the sign, and walk across the road.


  • This trail is quite narrow in places and there are sections, both in the forest and up on the ridge, where a slip or fall could send a hiker down a very steep slope. 
  • The trail in the forest is badly eroded in places and while easy to follow, one section traverses very steep slopes without a lot of vegetation to stop you if you should fall. The grade actually eases up the higher you climb.
  • The trail along the ridge and below the summit is narrow and traverses steep scree slopes. While the exposure is far from vertical it is steep and open and might make some hikers nervous, especially with all the loose rock on the trail.
