I did this in late July and it was hot, dry, and brown. A lot of this hike feels like forest roads, rather than trails. And there are lots of climbs. I'm not a big fan of climbing on forest roads and it felt like a slog. In spring, when it's green and not as hot, it might be worthwhile checking out.

This was a really nice trail. It's pretty strenuous though I wouldn't consider it super hard. There's a lot of ups and downs on it though and right away you're on a steep incline before it levels out on the top before dropping down a couple more times. It takes you through some different landscapes which is nice and it's a combination of wide trails and single track. Expect a lot of cows to be around but they didn't bother us much. Also saw a coyote and heard several others howling off in the distance. We didn't see many people and it was a beautiful day. This is a nice hike overall and would definitely recommend. I would not go if it's muddy though, the trails would be rough to hike through.
