A great loop hike for wildlife and wildflower scouting at the park in the hills east of San Jose. This hike gives a nice overview of Joseph D. Grant County Park, passing through its distinctive oak-woodland ecosystem but sparing you from the brutal ascents and descents that characterize so many of the hikes in this park. Grant County Park (often called "Grant Ranch" because the land was once owned by prominent ranchers of the same name) does not have the waterfalls or rock formations that popularize many parks in the Bay Area, but it was vast swaths of open, wild terrain. The wildness manifests itself in a wonderful wildflower bloom every spring along with a wide range of animals you'll rarely see outside a zoo: coyotes, turkeys, bobcats, tarantulas and the occasional rattlesnake or mountain lion. Scan the skies for raptors (red-tailed hawks are common; golden eagles fly by, too) and watch for old dead trees where acorn woodpeckers have stowed future meals. Trails on this hike: Dutch Flat Trail > Dairy Trail > Brush Trail > San Felipe Trail. This is also a nice kid-friendly day hike if you're camping at the park. Spring is naturally the best time to go, followed by fall and winter. Summer's just too hot to enjoy a hike here.Show more

One of the best hikes in the county park in the hills east of San Jose, California It starts at Halls Valley Lake and climbs steeply into the nearby hills along the Yerba Buena Trail (with a highly recommended side trip to McCreery Lake). It turns at the Canada De Pala Trail and returns on the Halls Valley Trail. Along the way you'll see sweeping vistas of the nearby Diablo Range along with the observatories atop Mount Hamilton, the highest peak in the South Bay. Wildlife sightings are common: hikers have spotted coyotes, turkeys, bobcats, feral pigs, tarantulas and even the occasional mountain lion. In springtime, this is one of the best wildflower locales in the Bay Area. Summer's too hot but winter's great (if muddy) and fall is interesting when the tarantulas come out. The park sits on lands once owned by a prominent ranching family (hence the informal title "Grant Ranch"). The hiking can be arduous -- many of the rails were built for people on horses rather than on foot -- but what you can see along the way makes it worth every arduous step.Show more

Length: 9.9 mi • Est. 5 h 3 m
If you like sweeping vistas and wildflowers, this is a hike you should consider. At ten miles, its relatively lengthy, but starting at Twin Gates eliminates some of the elevation gain and makes it a little easier in that regard. The Canada de Pala trail goes up from the parking lot, past the upper end of the Yerba Buena trail and crests at a place with a large fallen oak; a very nice place to stop and take in the view. A tall remnant of the long dead tree juts like a tooth at the crest of the hill. On a clear day you can see the bay as far north as the Dunbarton, and even on a foggy day the observatory looms above you from the peak of Mount Hamilton to the Southeast. The trail then dips down and crests again, just a little higher before it drops down and passes the upper ends of the Los Huecos and Halls Valley trails. In the springtime this trail is littered with a fantastic variety of flowers, but even in the winter, with a brisk wind clearing out the smog at the southern end of the San Francisco Bay, the views are awesome. Antler Point, is at the end of a 0.3 mile single track that cuts off of the main trail. The view is fantastic on a clear day down in the bay area. There's another beautiful overlook up there but it looks down into the Smith Creek canyon. Show more

A quintessential Bay Area climb, Mt Hamilton has killer views from a summit of over 4,000 feet, and has approach climb of almost 20 miles at a mellow grade. This ride starts and ends at the Warm Springs BART station. This can be ridden as an out and back or a challenging route ending at Pleasanton BART. Note: the roads around Mt. Hamilton can get very hot and dry, and there are no places to get food/water between the top of the mountain and Livermore.Show more

Length: 23.9 mi • Est. Multi-day
This loop hike across parallel ridges of Joseph D. Grant County Park offers sweeping views of the wild, mountainous terrain nearby and occasionally looks out over the southern end of Silicon Valley to the west. You'll see the usual Grant County Park attractions -- wildflowers in spring, tarantulas in the fall, raptors and coyotes all year -- while joining the elite few who have finished one of the Bay Area's most strenuous hikes. Best done in winter when the weather's cool but the trails aren't muddy (provided you can hike this many miles before sunset). Next-best time is spring, when the hills are green and the wildflowers are out. It's too hot in summer, and probably not worth risking in fall if you can't carry enough water for the entire day. This route goes to Antler Point, highest in the park; climbs Washburn trail, steepest in the park; and follows a long stretch of the Bay Area Ridge Trail, which has some of the best views. Show more
