Great spot to spend an afternoon. Remember to account for a long winding drive up and be prepared to yield to cyclists. (My utmost respect for the cyclists who pedal their way up!). The day was a bit hazy but no wind! We could see across the valley to the Sierras. Looking west can see the Golden Gate bridge. To the south, Lick observatory. Visitor center was interesting and very worthwhile. Great place to get a perspective for the entire Bay Area. Remember to bring binoculars.

My preferred method of travel to Mt. Diablo Summit is hiking, but when I'm introducing others to this iconic Bay Area peak I usually drive. At 3849 feet, Diablo is our highest mountain, so having a road to the top provides access to everyone! Summit Museum will introduce visitors to the significance of Mt. Diablo to the people who have lived on and near her over time. Flora and fauna of the mountain are represented and explained, and kids love the wildlife exhibits. On the upper level of the museum, the actual summit is exposed so you can get a peak photo. A raised relief map of Diablo with light-up way points highlights notable terrain. Let it inspire you to take a hike! On a clear day, from the summit observation deck, you'll be able to see the Sierra Nevada! Just below the summit is the Mary Bowerman Trail. At only 0.8 miles it circumnavigates the summit, giving you 360° views of the entire Bay Area. Along this path is an observation deck with telescopes to bring the view closer. Challenge your kids to find their house! Bay Area residents and visitors to the Bay should make Mt. Diablo Summit Museum a must-see on their bucket lists.

It was an amazing experience to be on top of the highest mountain in the Bay Area. The historical information was even more amazing. The drive up to the mountain is beautiful. The view is amazing all around.

Mount Diablo State Park is a must-visit! We came in June 2019 on a weekday and were blown away by the park's beauty. Nestled at 3,849 ft elevation, the drive in is breathtaking. We used the north gate entrance and parked at the upper lot. The vistas from the Mount Diablo Summit Observation deck are stunning. The Summit's "Eye of Diablo" beacon is a tribute to Pearl Harbor. The summit museum features the beacon, an observation deck, a visitor center, restrooms, and a parking lot. Don't forget to explore the museum during your visit. A fantastic day out!

This place is a must see spot for sunset. Beautiful views and amazing drive. The entrance fee is about $10 per car. And there's half hour long winding roads to the top! There's limited parking on the top. We went on a weekend and we still got a spot. There are a few vista spots on the way to the top- definitely worth stopping and getting some pictures. The drive is very scenic! Do checkout this place!

Got a Parks Pass from our local library and took a trip to the top of the mountain. Amazing views in all directions at the top. The museum is on the ground floor of the lighthouse so there isn't much to it but it was a nice/informative addition to our trip. It is definitely worth the trip to take it all in.

This is a beautiful summit with excellent views of all around the Bay! A must visit. Takes approx 40 mins to drive up/ down the peak from Danville. You gotta be careful of passing the bicyclists while driving up and super fast bicyclists coming down :) many view points and picnic tables for those who want to enjoy the environment!

Fantastic visitor center. Food and trinkets available. Informational video rooms and second floor has a amazing little museum and learning center.
