Starting from State Highway 231 northbound towards Chewalah and turn right on Hafer Rd. The turn left on Cottonwood Creek Rd and then right on Horseshoe Lake Rd. Finally, there is a left turn on Mud Lake Rd. This is somewhat rough and I would not do it after a heavy rain. Alternatively, follow 231 into town and turn right on Flowery Trail Rd to the other end of Mud Lake Rd. In any case, you can park at the Quartzite Mt Trailhead. There are several spots available up and down the road.
This summit was a nice (if somewhat steep in places) hike of around 1000' elevation and 1.5mile OW.
Along the way there are several rest benches and a mailbox containing a hiker's logbook.
There are trees at the summit to throw a wire into. The day I went, there was quite a bit of QRN across several bands but I was able to get enough contacts for both SOTA/POTA activations.
