Just north of Napa outside the town of Calistoga sits one of the coolest, least known mountain bike trails in Northern California. Oat Hill Mine trail starts just outside of Calistoga and climbs up to the Palisades. This trail has some of the best technical climbing in Northern California. There is also a huge section of technical trails at the top of the ride. The ride report is old but you can Check out the Pictures from our ride last weekend.
