A good option for Dispersed camping if Lake Wenatchee State Park campground.  This is a at the Lake Wenatchee Airstrip Snoparks at the junction of 207 and 22 near Lake Wenatchee and Fish lake. There is a large parking lot and some pull outs off an old forest road the loops around from one side of the road to the other. Quiet in the spring. No facilities and good AT&T cell reception.
