I agree, lots of solitude and incredibly quiet. Nice if you want to do a long loop. And not many hikers. Not as flashy as some parks, but there are a few nice views of the ocean, and some other points of interest.
Way back in the late 70s, I was hiking in Butano and came across a couple boinking in the trees way back in the wilderness. They had left a six pack of beer on the nearby picnic table and I was tempted to have a seat and a cold one, but I did the gallant thing and continued on, although I did hear a female voice say “What was that?”
I had another such encounter over in Sunol Wilderness on a remote ridge top where I came upon another such amorous couple.
I always thought it sad my hikes weren’t like that. My friends at work always chided me about my famous “Sex Hikes” where everybody else was getting it.
