Quartz Mountain is south of Republic, WA – we used a USFS dispersed parking and camping area on Hall Creek Road, just south off Hwy 20, as our trailhead.
Quartz Mountain summit
There are great 360 degree views from Quartz Mountain summit!
The 4010 trail is called Quartz-Hall Tie – it’s listed as a 50″ trail on the MVUM but the boulders have been moved and the signs removed. It serves as a nice side trail with some slightly challenging ruts to connect 2 sections of USFS road.
