The paved, 1.2-mile Valley of the Moon Trail runs through the center of Sonoma Valley Regional Park and is ADA-accessible. The trail borders a seasonal creek and curves through a beautiful woodland of oaks draped in lichen. Tables placed along the way are great picnic spots.
The 1.15-mile Woodland Star Trail climbs from the Valley of the Moon Trail to a ridge on the park's southern boundary and follows the wooded hillside across the southern edge of the park before descending near Arnold Drive. The trail offers occasional views of Sonoma Valley.
Several smaller trails also connect the Valley of the Moon Trail to the surrounding ridges.
The 1.5-mile Cougar Trail passes through a recent addition to the park's northern boundary and offers sweeping views of the Sonoma Valley and the Mayacamas Range. The property is an important piece of the Sonoma Valley Wildlife Corridor, a collection of protected lands allowing animals safe crossing on the valley floor.
