What? : Mt. Diablo State Park is formed around the 3,849 feet Mount Diablo near Danville, CA. Many visitors to Mount Diablo head straight for the Summit to enjoy the view but I recommend to combine this with one of the many hiking option this park has to offer, see below for different hiking recommendations.
The large 20,000 acres park has unique geological landmarks and many outdoor recreational activities options, including: hiking, cycling and mountain biking.

Turn on Alameda Diablo and follow until South Gate Rd.
North Gate Entrance:
Take Highway 680 to Walnut Creek. Exit Ygnacio Valley Road, turn on Oak Grove Rd. and continue until it turns into North Gate Rd.
When? : The park is
open year round. At winter it can get some snowfall and in very hot summer days
the park may be subject to closure due to extreme fire danger.
At cloudy days
you can have full coverage of cloud with no or limited visibility. At summer
days the haze and the hot atmosphere will limit the visibility.
The best time
to visit here is at nice winter day or early spring where all is green, and you
can enjoy the flowers.
Due note 1: Mt. Diablo
State Park is a world-class venue for mountain bikers and road cyclists. When driving
on the park roads watch for cyclists on the main park road. Stay in your lane
on blind curves and do not cut corners. Pass with care only when you have good visibility
forward and you can see for sure there is no other incoming car or cyclist.
Due note 2: At winter and
cold days Mt. Diablo can have it “own weather”, especially near the top of the
mountain, check in advance and come prepared.
In cloudy days
the summit can be completely covered with clouds and fog with no visibility.
Due note 3: There is 10$ per vehicle day use entry fee to the park and you pay it at the Gate Entrance. Gates are closed to arriving visitors at sunset.
