William R. Mason Regional Park

The first phase of the Mason Park, forty-five acres, opened to public use in 1973.

A 50-acre (200,000 m2) second phase was completed in 1978 that included a 9.2-acre (37,000 m2) lake which has proven to be a popular attraction.

It features scrub-covered ground, traversed by a bike trail and a small creek.

Though a ring of wilderness surrounds this side, it is mostly flat grassland, with an occasional hill or rise.

Its numerous trails eventually lead to Ridgeline, a street that connects Turtle Rock Loop to University Drive.
