Ridgeline is a must ride in the DuPont. It is very fast with lots of small rollers, and berms. It has a technically easy climb, but still rather steep. Right before you get to Ridgeline you can connect Hooker Creek which is a shorter version of Ridgeline.
Hooker Creek Trail is a short downhill trail that ends with a punchy climb that spits you out near the top of Ridgeline Trail.
