The Iron Horse Trail, open from 5 a.m. to 10 p.m., stretches 32 miles between Concord and Pleasanton, following the former Southern Pacific Railroad. The latest segment, connecting Pleasanton/Dublin BART to Santa Rita Road, opened in 2014 after nearly 30 years of planning. This multi-use trail links residential areas, schools, parks, and public transportation, providing a trail to the local community. This paved trail crosses roads but is a safe way of getting around away from traffic.

Very pleasant creekside dedicated bike trail. Well paved and flat, it connects with Iron Horse Trail and its wider trail system.

This point is about halfway up to Mount Diablo. The view from here is stunning, offering vistas of rolling hills and lush green surroundings. If timed right, springtime wildflowers add an extra bonus to the experience.

One of the fiercest peaks in the Bay. Always worth the effort. It’s often much cooler on the summit than the rest of the trails — there is a water spigot up there to fill up bottles. Also a store is open at some times. Don’t bank on it.
