The cache is located on the southern summit of Silver Star Mountain.
Multiple ways to approach. The most common routes are via the Grouse Vista Trail, Ed's Trail or the Silver Star Trail. You now need a WA Discovery Pass to park at the Grouse Vista and Silver Star 180 TH, and a NW Forest Pass to start at the Northern TH (Ed's Trail).
Silver Star has two summits. The north summit is the true summit, and is a former lookout site. You can see bits of the old foundation there, find a benchmark and sign the summit register. The cache is located nearby on the south summit.
