If you make the summit a fantastic view awaits. Be aware the road goes down then up to the road about then up again to the summit!…

Still one of the highest points in the Santa Cruz Mountains, even though the military graded and flattened the actual summit to create an Air Force base. The summit was cleaned of hazardous material in 2009, then carefully restored after a lot of community input. It's a lovely place to visit now!

Stepping through McAbee Entry transports visitors back to Almaden Quicksilver County Park's mining past. Once site of the world's second-largest mercury mine, the gateway now leads to scenic wilderness instead. Just beyond the entrance, trails wind through natural habitat rather than tunnels burrowing for ore. But with every step, the land's history rises as relics of a roaring age wait to be discovered anew.

Getting to the top of Eureka Canyon not only means that the climbing portion of you trip is over, but also that you will soon enjoy smooth pavement if you travel Northbound
