Personally wasn't a huge fan, a couple trails on the route are taken in the less popular direction, east and serpentine. Would rather have gone around to ride those going down hill. I would make my own route next time

A fun route. It's worth turning south on the way back and climbing up Lake Loop so you can ride Serpentine in the downhill direction.

We hope you've been enjoying Trailforks!

Rutted as usual, but choosing your line through is what makes it fun. Dry but tacky.
