The Cascade Picnic/Gurley Saddle Road goes from FS 209 to FS 534. Starting on FS 209, the road is FS 610; at the FS 534 end, it is FS 379. The number changes at some point. It is a narrow, often-shelf, gravel-to-dirt road with numerous switchbacks as it climbs up and over the pass. There are at least two places on the side of the road where it has collapsed and been partially repaired; at this time, they are well-marked. Former users have mostly cleared many downed trees. Unfortunately, the people cutting the trees back provided barely enough room for a full-size rig to navigate the gaps. It can be done, but it's pretty tight in some places. Even so, it is not a difficult road to drive if proper care is taken.
Dispersed camping is allowed, and there are a few established sites, both up on the top ridge and on the more level areas at the beginning and end of the road. Going up and down from the ridge, the road is relatively narrow, and there isn't much room for a dispersed camp.
