Drive east on I-90 and take Exit 54 (Hyak). Turn right and then left into the large Hyak ski area parking
lot. Drive through Hyak Estates on Hyak Drive
East. Continue past a sewage treatment plant. Just past the sewage plant,
turn on FS 9070 and drive 4.6 miles, passing trailheads for Cold Creek,
Mount Catherine, and Twin Lakes, to the PCT at Windy Pass. The trailhead is
on the left side, and can barely be read as "Mirror Lake".
**NOTE** The turnoff for Silver Peak from the PCT is not signed.
