How about doing the entire Ohlone Wilderness Trail, in the Eaat Bay, connects Mission Peak and Sunol regional parks, about 28 miles, with some good climbs (including Mission Peak). Here's a link: http://www.ebparks.org/parks/ohlone

Hi Alex -- The Ohlone Wilderness is a great hike. You can do a one-way hike from the bottom of Mission Peak in Fremont, ending at Del Valle Park.

Three other suggestions for one-way hikes:
1) SF at the Golden Gate Bridge, to Bear Valley Visitor's Center at Point Reyes
2) Sanborn County Park (Saratoga) to Waddell Beach in Santa Cruz County via Castle Rock and Big Basin State Park;
3) Castro Valley to Richmond, starting at Chabot Regional Park, ending at Wildcat Canyon.

Can you tell I used to like the long ones?

A Question
Are we talking about a one day trip or over a few days?
Thanks
Zoya
