Our second time to Mt Diablo, always breathtaking. The drive/ride up the mountain has a lot of curves which seem to go on forever, but it's worth it. Make sure you check out the viewing platform.

The drive to the top is rewarded with views to the west of the SF/Golden Gate Bridge and the snow capped Sierras to the east

My husband and I recently hiked up to the waterfalls on Mt Diablo from the Regency Gate trailhead in Clayton. On the way, there are spectacular views of Clayton and beyond to the Delta. The trail is a bit harrowing in parts and challenging for a couple of 70 somethings. Be sure to take water and a snack or a... More

It's the Wandering Yank here. Mrs. Yank and I had last been to the top of Mt. Diablo many years ago, so it was time to see it again. And very nice it was! It's a long windy drive up, and since it was a spring weekend, there were lots of bicycles creeping up. That definitely slows down the drive,... More

Mount Diablo State Park is one of those easy to access ecological treasure in the San Francisco Bay Area. The summit is 3,849ft with many narrow roadways,steep climbs and bent curves however the trade off is having incredible vistas of San Francisco and its Bay. Despite even in the car the climb is scarily difficult, Mount Diablo is very popular... More

It was rainy and did not get the chance to experience a lot of the views or the trails. The park offers a lot of picnic areas and hiking options. The Visitors Center is well kept and has a lot of intereatininteresting displays.

Beautiful views of the area, couldn't have asked for a greater day to view during the week. $10 entry so pile up your vehicle and make it a day. Bring your family during the cooler months so you don't bake on the southern face.

It's always there but don't take it for granted. I grew up literally a couple hundred yards from the foothills of the Rocky Mountains in Colorado. I loved the mountains and spent a good deal of time in them but without context probably took them a bit for granted. I swore upon spending too much time in places without mountains... More
