      The grass is high and riding through it was tight. The trails under the cover of trees are perfect and clear. These trails are so amazing every...

       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

       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.

       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.

       How long would it take to pedal up thrillium on an e-bike?

       @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.

       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!
