Super nice trails up here. Jeopardy is my favorite, there are pleanty here once you're at the top on the mountain. The climb isnt too bad, there is now 2 ways to go up, one that is steeper and shorter, the other one is a lot less steep but will take 30+ more minutes to get to the top.

Beautiful scenery and a great place to bike up to. Fun seeing cows walking about and a great place to take the kids for a hike to get their energy out.

This trail is a decent hike from top to bottom. Biggest draw back is no shade for majority of trail. Would be awesome winter/spring trail. Nice views of the bay at the top as you can see everything around.

Big rock loop trail is a great hike with awesome 360 views from the top of the trail. It's about a 5.25-mile loop with a steep uphill for the whole first half of the hike, so good shoes and relative fitness is advised.

Only side of the road parking. No parking lot there.

Can you bring a dog on leash on the trails?
