This is a really straight forward hike up a fire road from Gaviota State Park into Los Padres National Forest.
The hike starts out climbing, and mostly keeps the same elevation profile the whole way up. Half a mile into the hike, there is an unmarked path headed toward the hot springs. I took this path on the way up, which continues past the hot springs back to the road. There were a couple of bathers.
The rest of the way up was just a steady trudge up the mountain, on a road passable by a civic. Really beautiful santa barbara coastal-springtime views the whole way. There aren't many signs, but its never very hard to figure out.
The peak has a summit log and a benchmark. At the peak, the trail actually continues and you can take another way down (Trespass trail). Its longer, but less steep.
Gaviota Hot Springs
1 mile round trip from the trailhead. Some consider it a slight bushwack. Be aware of poison oak along the way.
Cambell Trail Loop
A loop with the old defunct Cambell Trail is about eleven miles.
