Mission Peak is a popular destination. On the weekend, it is packed with hikers going up and down from either Stanford Avenue or the Ohlone College entrance. For biking, it's the ultimate challenge and usually can be done using the Peak Trail.
Peak Trail begins from the Ohlone College park entrance.The first 0.5 miles after the second cattle gate is brutal and pretty demanding. If you can climb pass that, everything else is easier.
The trail has a pretty nice and shaded singletrack. That section is pretty fun going up or down. Always keep an eye out for hikers. Sometimes you may run into cows as well, but that usually happens before the third cattle gate.
After the singletrack section, the trail continues with a moderate ascent all the way up to the restroom. In 2015, a bypass section (illegal) was closed down and replaced by a longer section. The new section has two long and steep hills all the way to the final ascent. If you want to get to the top, you have to hike your bike from here.
You can return back down where you came from or continue to head toward Eagle Loop Trail
then use Eagle Trail
to head back down. Back at the restroom, there are a few alternative options to head down using Hidden Valley Trail
or Peak Meadow Trail
. If you take one of these routes, you may have to ride Mission Blvd back to where you came from.
