Local tips

Arrive early, especially on weekends, to secure parking at the summit, as spaces are limited.
Bring binoculars to enhance your viewing experience from the observation deck and spot distant landmarks.
Visit after a winter storm for the clearest views, as the air is often cleaner and the Sierra Nevada mountains are more visible.
Check the Mount Diablo State Park website for information on guided hikes and interpretive programs.

Getting There

Driving

The most common way to reach the Mount Diablo Summit Museum is by car. From Walnut Creek or Danville, follow signs for Mount Diablo State Park. There are two main entrances: North Gate Road (from Walnut Creek) and South Gate Road (from Danville). Both roads converge at the Junction Ranger Station, where you'll pay the park entrance fee. As of July 2025, the vehicle entrance fee is $10, payable by cash, check, or credit/debit card (when kiosks are staffed). From there, continue on Summit Road to the summit parking area. Parking at the summit is limited and can fill up quickly, especially on weekends. Be prepared for winding roads with hairpin turns. Allow ample driving time, especially during peak season. Parking is included in the park entrance fee.
Public Transport

While public transportation doesn't directly reach the summit, County Connection buses offer service to the vicinity of Mount Diablo State Park. From there, you can bike or hike into the park. However, be aware that the final ascent to the summit is steep and challenging. From the bus stop to the summit, expect a strenuous uphill journey. There are no additional public transport costs beyond the County Connection bus fare to reach the park's vicinity.

Discover more about Mount Diablo Summit Museum and Trailhead

The Mount Diablo Summit Museum, located within Mount Diablo State Park, is more than just a museum; it's a portal to understanding the mountain's significance, geology, and diverse ecosystems. The museum resides in a historic stone building, a testament to the craftsmanship of the Civilian Conservation Corps (CCC) in the late 1930s. The building itself was constructed from fossiliferous sandstone blocks quarried from within the park. Look closely, and you'll spot ancient marine fossils embedded in the walls. Inside, impressive exhibits chronicle the history of the mountain and capture its majesty. A rock wall with an instructional video examines the geological forces that created the mountain. Panels describe the Native American history of the region, highlighting the cultural and spiritual importance of Mount Diablo to indigenous tribes like the Miwok, Ohlone, and Bay Miwok peoples. A diorama, complete with native sounds, offers an overview of the park's ecosystems, while a model acquaints visitors with important park locations. The Summit Visitor Center is open from 9:30 a.m. to 4:30 p.m. daily. Admission to the museum is free, though there is a park entry fee. The museum also features a gift shop and an audio-visual room. An elevator provides access from the lower level entrance to the upper museum floor and observation roof. On the walk up the circular stairway to the observation deck, visitors are treated to a look at ancient marine fossils embedded in the sandstone walls. Above the rotunda is a beacon, historically important to aviators and now lighted once a year on December 7 in memory of those who lost their lives at Pearl Harbor. Outside, an observation deck provides some of the most fantastic views in the world. On a clear day, you can see the San Francisco Bay Area, the Sierra Nevada Mountains, and even the Farallon Islands. Telescopes are available to enhance the viewing experience. The museum also serves as a trailhead for various hiking trails, including the popular Summit Trail.
