Since it opened in 1969, Hidden Valley Regional Park has been offering visitors plenty of ways for the entire family to recreate. Built on 480-acres deeded to Washoe County from the Bureau of Land Management, the park was envisioned to be “comparable to any in California or anywhere else in the United States” and it certainly has lived up to those expectations.


Over the following decades, many additions and improvements were made to the park. A 40-acre grant from the BLM gave the park picnic sites, riding and hiking trails, and a small pond on the Boynton Slough with trees and grassy areas. In 1978, the county announced that it would develop ten acres with tennis courts, jogging paths, and picnic areas. Public input was solicited in 1990 for a group picnic area and horse arena. New playground equipment, lawn and picnic shelter were added in 2007. The following year, local philanthropist Link Piazzo donated a dog park. Benches shaded by trees were also included.
