Located on the eastern edge of the San Francisco Bay Area, the Arroyo Mocho Trail is a tale of two trails. From its western starting point at West Las Positas Boulevard in Pleasanton to near El Charro Road (about 5 miles), its surface is loose gravel interspersed with some brief paved areas. If cycling, wide tires and experience on loose gravel are recommended. This section is quite suitable for walking and jogging but is not wheelchair or road-bike friendly. The trail runs mostly below street level here and follows the Arroyo Mocho. A paralleling upper trail allows access to the surrounding neighborhoods and nearby Ken Mercer Sports Park. East of El Charro Road, the trail runs alongside major roadways but is separated from them and feels safe from traffic.
The first 9 miles of trail offer little to no shade cover or easily accessible water, so plan ahead on hot days. As the trail approaches Livermore, it transitions to a more neighborhood feel. The Livermore area is home to many wineries and a brewery not far from the trail. This portion also has many direct access points from the surrounding neighborhoods, which are filled with citrus trees and grapevines that make for an inviting backdrop. For 2.2 miles, the trail meanders through several parks and natural areas with more shade available. There is an equestrian arena at Robertson Park, as well as restrooms and water.
Just east of Robertson Park, the trail branches both north and south. The north branch takes you around Sunken Gardens Skate Park (aka Livermore Skate Park) and ends in a residential area at Almond Avenue. The skate park offers parking and drinking fountains but no restrooms. The south branch of the trail continues 0.4 mile before splitting at Concannon Boulevard: The northeastern route heads toward Bruno Canziani Park, which has parking, drinking fountains, a dog park, and children’s play equipment but no restrooms. The southwest branch takes you along Concannon Boulevard to Normandy Circle. You’ll travel through a vineyard area with a winery adjacent to the trail.
The Arroyo Mocho Trail intersects with the Isabel Avenue Trail at Sant Rita Road bridge and at Stanley Boulevard.
You can access the Arroyo Mocho Trail from any of the parks through which it travels or intersecting streets. Parking is available at Ken Mercer Sports Park (5800 Parkside Dr, Pleasanton), at Robertson Park (3200 Robertson Park Rd, Livermore), at Sunken Gardens Skate Park (3800 Pacific Ave, Livermore), and at the Robertson Park Disc Golf Course (1505 S Livermore Ave, Livermore).
