Mountain Biking Thrillium

****   Add a review
#77 of 1,205 mountain bike trails in Washington
#3,843 in the world

Steep, fast, DH course with big jumps, drops, and tabletops. You can ride it on any bike and all features are rollable, but beware... it's rough.

    Looks to be a good track during dry weather. It started to rain yesterday, and puddles formed. very slippery when wet in the clear cut sections. Nice jumps with some deep banking turns. Good run

    This is the PDX area premier DH trail. Unlike other DH trails, this one is well maintained CCMTB club and relatively sustainable. You can ride this thing on any bike, but you are best suited with at least 6" or better, a dedicated DH. DO NOT climb this trail! please shuttle or climb Cold Creek to top of TH. Upper is natural rugged with drops. Lower (starting at clear cut) has huge table tops and jumps, big berms and fast terrain.
