Probably the best section of trail on the Juniper hillside. Most trails cross back and for forth, but this has some great flow with cool structures and lots of rock kickers and little drop options.

Super fun trail.
I like taking the OHV road up to the top of the mountain and then hopping on Ridgeline to get to the top of Big Thunder. Big Thunder is super fun -- especially after riding it multiple times to know how to hit everything really good. It is kind of tricky to know where to go at first because there is kind of a web of trails.
If you follow the trails correctly it will put you right at the top of 220. Big Thunder + 220 is the best combo of trails at Eagle Mountain.

The ride up to the top is completely ridiculous! But, once you get to the top very much worth the effort. Skinnier, drops, women berms, techies, and more. Slam it, send it!!! Do it today!!!
We hope you've been enjoying Trailforks!
