William R. Mason Regional Park, Regional park in Irvine, California.
William R. Mason Regional Park, known as Mason Park, is a regional park in southern Irvine, California, split into two parts by Culver Drive. The west side is mostly flat grassland around a 9.2-acre artificial lake about 900 feet wide and 800 feet long, often visited by migrating birds. The east side is a scrub-covered wilderness area with a bike trail, a small creek, and a large palisade along its southern edge.
The first 45-acre phase of William R. Mason Regional Park opened to the public in 1973. A second 50-acre phase was completed in 1978, adding a 9.2-acre lake that became a popular attraction. The park is named for William R. Mason, president of the Irvine Company from 1966 until his death at 54 in 1973.
This park serves as a gathering place where people come for organized events and outdoor recreation throughout the year. Visitors participate in activities like model boat sailing and enjoy the green spaces as a social hub for the community.
The park operates during specific hours that vary by season, so it is wise to check timing before your visit. Parking is available on-site and visitors should plan enough time for their chosen activities given the size of the grounds.
Mason Park is split by Culver Drive: the east side is scrub-covered wilderness crossed by a bike trail and a small creek, and its southern edge ends in a large palisade marking the park boundary on the northern edge of the San Joaquin Hills.
