Nothing devilish here. Just a nice spot to hike and picnic. The top of the peak has some great views.

The park has great trails and the road to the top is very good for bicyclists. Bring lots of water during the summer. The views from different locations are incredible

I live nearby and I get to see the mountain everyday - it’s one of the special things I like about living here. The best time to visit is spring when the grass is green but it is beautiful all year round. Be aware that...More

Great walks. Choose your challenge. Access to the summit if you are up for it. Many bird species to observe. Watch out for local snakes. North entrance is bike & horse friendly also. Shaded picnic area by the creek. $6 parking daily fee.

We just climbed the big stone boulders which i'm sure she would be able to do. We saw other kids her age doing them. Hope that helps.

I did go to the website and decided to try here for an answer. Since then spent one night at Juniper site no area to jump in water or fish but a very nice campground and not far to the peak. I will return for more.
