Editor's note: BART is currently running reduced service with dispatched long trains to ensure riders have room to socially distance. If you plan to ride BART, see our feature, Tips for riding BART during COVID-19.

Before heading out, please be aware of local requirements on social distancing and wearing a mask. Alameda County and San Francisco city health officials require residents to wear face coverings any time they leave home and get within 30 feet of anyone not living in the same household. If you need a mask, check out our feature, Bay Area businesses selling masks during COVID-19


The title of this article is a bit of a stretch. Groundhogs of the Punxsutawney Phil variety are not found in California, as they generally live east of the Mississippi River. However, groundhogs are just large ground squirrels, and ground squirrels are found in California. The biggest ground squirrels in California are yellow-bellied marmots living in the Sierra Nevada Mountains.

But you don’t need to go all the way to Yosemite in search of ground squirrels. We have a population of them right here in the Bay Area. They’re particularly fond of living in the Diablo Range and are commonly found peeking from their burrows in the Mission Peak Regional Preserve. On February 2, follow our hike below to see if these ground squirrels cast a shadow and find out if we’ll be treated to an early spring.

What to bring

Comfortable shoes, water, sun protection (hat, sunscreen), extra layers or rain gear (just in case). A smartphone is handy for maps and looking up information or taking photos. And, of course, your Clipper card. Make sure to download the Ride with GPS app (the app is used for planning bike routes, but works for hikes too) so you can easily reference the route.

How to get there

The hike begins directly outside of the Warm Springs/South Fremont Station. Exit the north side of the station, turn left on Warm Springs Blvd, then turn right Grimmer Blvd to head towards the hills.

Once you've entered the park, follow Hidden Valley and Ohlone Wilderness trails until you reach the Peak Trail, which will bring you to the Mission Peak summit. From there, follow the Horse Heaven and Peak Meadow trails back down to complete the loop portion of the hike.

About the park

Rising steeply to the east of Fremont, you’ve probably noticed the dramatic Fremont, Mission and Monument peaks when riding BART through the area. The Mission Peak Regional Preserve has more than 3,000 acres of rolling hills, with numerous trails leading up to the park's highest points. From the top of Mission Peak, you’ll be rewarded with views of Mount Hamilton to the south, the Santa Cruz Mountains to the west, Mt. Tamalpais to the north, and Mt. Diablo and the Sierra Nevada to the northeast. Along the way, you’ll share the hike with cows, hawks, vultures, and a herd of feral goats roaming the cliffs.

Once you've reached the summit, the hard part is over. From there, it's all downhill back to the station.

Let's take a hike.
