The Transition Bikes CDC: Yacolt Burn Enduro full course for Pro, Expert and Hardtails.

Few changes from previous years.
1. No more road climb to the towers. After racers pop out at the Thrillium parking lot they will take the new two-way trail called Beargrass to the start of stage 1.
2. The Upper Cold Creek trail will tie into the Sixth Sense Connector for stage 1.
3. Lower Cold Creek will finish up the trail a bit from previous years to remove the pedally bottom section.

Feed Station and evo Neutral Support will be at the bottom of Sixth Sense.

Spectators have easy access to the bottom of Stages 2, 3, and 4.

Steep and loose, black/blue, super fun, hold on tight and be ready for baby head sized rocks all over

Super fun. The speed needed to hit all the intended landings is intimidating. Definitely a trail to progress on.

It's easy to miss the entrance so keep your eyes open. This route up is much better than going all the way to the yellow gate and then climbing the shuttle road to the parking lot.

Kind of an unrelated question, but is it legal to target shoot near thrillium? I constantly hear gun fire and see casings on the climb up from the parking lot below for road 1070. Thanks.

Tough climb, but it has gotten me in pretty good shape. Have yet to see anyone descending on this trail. Good one for those like me who find the fire road boring, and want a mellower warm up before getting their ass kicked.

A shady alternative to climbing the fire road. Starts off mellow but the second half will kick your ass. If climbing up the second half, definitely look out for descenders skipping the first half of lower Cold Creek who will be flying down the trail.

Awesome enduro trail with rocks, roots, and flowy berms with the occasional jump and drop thrown in. Like lower Cold Creek but with less tech and fewer and smaller jumps.

Don’t climb this trail. It should be downhill only. Aside from how steep it is in spots, there are several blind corners and jumps.

Took a gamble to hit this bad boy! On the way to vacation And it was worth every second! Best trail ive hit in 5 years its as close to park flow ive seen. The jumps are really long so I cased alot of them but the rockgarden is the best ive ridden in years if not ever! What a gem!

@salamander-workshop: under no circumstance should any person pedal up thrillium. Take road 1070 and Ross’s Grade up. The moment you drop in for the descent you’ll realize why no one should ever climb it. It’s concerning that it’s not officially DH only.

It's like the builder's goal was to create an enduro stage with everything great that the PNW has to offer. Seriously fun.

This trail is a lot of fun! After some in our group got more than they bargained for on the upper half of Cold Creek, we decided to hit this trail up to finish our descent. If you want steep and technical, this isn't for you, but if you like jumps and flow, it's great. The builders did a great job, with a section of bermy goodness in the "middle" of the trail that is something to behold. Next time out I would climb the road (Murphy's Grade sucks IMO), and ride this and/or the lower half of Cold Creek depending on who I was with and what type of trail I was after.

Can't say I really enjoyed this trail. It's obvious this was not a purpose-build MTB climbing trail. It's super rocky, but what I found most annoying were the many sections that are very steep, and with no switchbacks - just straight up, up, up. It's only real upside, vs the road, is that it is shaded. Still, next time I think I would just suffer on the road.

An absolute classic blue trail. Intermediate features but fun for every rider. Can be ridden as fast or as slow as you like and has enough interest to make it rideable dozens of times a season. Graded perfectly!

I agree with other's comments. Curious why is this is marked as a bi-directional trail though? Pretty sure it's one-way and that's downhill.

Trail Thrillium
Thrillium is such a compelling trail, probably the best gravity trail in 200 miles in any direction. Significantly harder than most single blacks in the area. While it is probably a single black to ride it, it definitely enters double black territory if you're riding it anywhere near fast enough to clear the features.

This trail is sick! Best of all worlds and an amazing shuttle run! Start out with some very fun flowy tech and then finish up with some large jumps and step downs! An absolute blast! One of the best gravity trails

The road to Thrillium trailhead is still closed, and I'm sure the entire trail is snow covered, based on lower Cold Creek being snow covered.
