With many miles of mountain biking trails spanning a wide variety of skill levels and physical challenge - including a bona fide double-diamond DH trail and killer views of Mount Rainier from the summit - Tiger Mountain is one of Seattle's most popular mountain biking destinations.
All trails are open year round, but during the winter months or after significant weather events, the trails are subject to closures: check for updates on this page and on the DNR's Tiger Mountain page here.
There are also many miles of logging roads that are open all year long, but these too may be closed (typically for timber harvest). Check the DNR link above.
3 New Trails Open on East Tiger Mt: "Easy, Tiger" , "The Legend" and "MegaFauna" form a lollipop loop off of the Northwest Timber trail. Easy Tiger is a green level 2-way trail that will primarily be used as the return path for The Legend, the more difficult black diamond descent. MegaFauna is a gnarly double black diamond descent.Construction of extensions to the trails will continue this fall. Eventually Easy Tiger will connect all the way to the Raging River State Forest!
