The story behind why the Tri-Valley region has more open space than urban sprawl is long and complex, but there’s no arguing with the results! All four towns in the region are situated in close proximity to parcels within the vast East Bay Regional Park system, where dogs can hike with their people off-leash in many open-space and undeveloped areas, provided they are under strict voice control at all times.
Just outside Pleasanton, for example, Pleasanton Ridge Regional Park is 5,271 acres of open space centered on an oak-covered ridge overlooking the town and the Livermore Valley. Elevation in the park climbs to a stout 1,600 feet, with a trail system accommodating hikers, equestrians and cyclists.
In Danville, Sycamore Valley Open Space Preserve covers two main ridges within a region of rolling hills south of Mount Diablo. The Shelburn portion is mostly grassland, while the northern unit (best for hot days) is mature woodland.
Dublin Hills Regional Preserve, near the town of the same name, spans 654 undeveloped acres bounded on the south by Interstate 580. A 3-mile segment of the Calaveras Ridge Regional Trail provides local access and excellent views, delivering hikers to a grassland area largely untouched since the 1800s.
Del Valle Regional Park is the crown jewel in the Livermore area. Its 5,000 acres, set among oak-studded hills with a lake at its center, encompass 67 miles of trails and a popular campground. It’s also the gateway to the 28-mile Ohlone Wilderness Trail.
