Tiger Mountain accessed from I-90 at High Point. WTA will work on upgrades to the Tiger Mountain Trail (TMT) from the intersection with the Highpoint Trail west towards the Tradition Plateau. The tread needs to be widened and moved back up hill in a few areas and some work needs to be done to improve a couple of switchbacks.
You will be given a voucher on this work party as part of the Discovery Pass volunteer program. Volunteers can earn an annual Discover Pass after completing 24 hours of service (typically 4 days) on qualifying projects. To learn how you can exchange your vouchers for an annual pass (as well as exclusions), visit the Discover Pass website at http://discoverpass.wa.gov/
Tiger Mountain could be the most heavily trod upon 3,000 foot hill in the U.S., since it is open to hikers, horses, and dogs, with mountain bikes allowed on some trails. This has been a popular wooded peak, as it is set in Issaquah's backyard. In 1980, the land was designated a state forest and the trails have thrived. About 60 miles of trails web the hill, making loops ranging from a mile to a dozen miles, and the upper trails provide some excellent views of Mount Rainier and the Puget Sound lowlands. This trail network is open all year around, and it's not unusual to see 200 cars at the High Point Exit during a summer day.
