It’s impossible to talk about mountain biking in the Pacific Northwest without mentioning Tiger Mountain. According to local mountain biker Asa, "Tiger Mountain is often regarded as the PNW mountain biker’s mecca.”


Tiger Mountain is also renowned as one of the most difficult trail systems in the Seattle Area. “The trails on Tiger are fierce, daring, and among the most aggressive in the Evergreen State,” writes local mountain biker Chris Daniels. And the deeper you dive into the trail system, "the more extreme and difficult it gets.” Of all the trails on the mountain, Predator is hands-down the most difficult. This experts-only trail "features 1.8 miles of steeper and more challenging terrain, including a committing rock waterfall chute,” according to EvergreenMTB.org. "This one-way descent is full of rock-armored steeps, with some tight turns over fast and undulating terrain packed with obstacles that will keep even highly skilled riders challenged,” they continue."

Very steep, difficult, narrow singletrack with widely variable and unpredictable trail conditions. Unavoidable obstacles could be 15in/38cm tall or greater, and unavoidable obstacles with serious consequences are likely to be present. Obstacles could include big rocks, difficult root sections, drops, jumps, sharp switchbacks, and more. Ideal for expert-level riders.
