About This Trail

Imported description

You cannot continue if you cross a bridge. The switchbacks are short. It's a historic mineral spring spa and there's lots of shade. This is a great hike in the summer because of the shade. Take a look at the remnants of the spa. The trail starts paved and goes to dirt pack. The trail leads you to Alum Rock. The trails are shared with both bikes and equestrians. The elevation climb is less strenuous because of some switchbacks. Dogs are not allowed in the park, and there is a fee for parking inside.
