Hello, I've recently gotten into hiking, and I went on a pretty challenging one a few days ago in the east bay area. It was about 9 miles long and had a fair amount of uphill climbing, definitely took me by surprise.

I think I enjoyed it more because it was almost entirely empty, only saw a couple passerby's during the entire hike.

Anyone know of a good trail thats long/challenging like this where i'm not likely to see many/any people?

I live in the Sacramento/Stockton region and would be willing to travel up to 1.5 hours away.. Thanks!
