Castle Crags Dome Hike
@CAStateParks
About an hour and half drive south of Ashland on I-5 will put you in Castle Crags State Park. There are several hikes to choose from; we did Castle Dome and Indian Springs which total about 6 miles. That may not sound like much, but with over 2,200 feet of elevation gain (and, of course, descent as well) this is a strenuous hike. The views are totally worth it though.
Indian Springs is probably skipped by most, but I found that little piece of the hike to be totally worth it (on the way down).
