Hidden Valley Regional Park is part of the system administered by Washoe County Regional Parks and Open Space. It is a wonderful family park with a wide variety of features designed to accommodate various recreational activities. I particularly like the mix of developed and undeveloped areas within this 480 acre park.
What To Do at Hidden Valley Regional ParkHidden Valley Regional Park has restroom facilities, the rentable Vista Group Picnic Area, individual picnic areas available on a first come basis, tennis courts, volleyball court, horseshoe pits, children's playground, dog park, horse arena with announcer's stand and grandstand area, and hiking, biking, and equestrian trails.
Only 65 of the 480 acres are developed. Part of the undeveloped terrain takes in a large flat area between the Hidden Valley subdivision and the Virginia Range rising abruptly from the valley floor. Old dirt roads meander through this area, making it suitable for easy walking and biking.
The hike up into the Virginia Range is a strenuous one. It's basically straight up on any of many use trails hikers and wild horses have worn into the slopes over the years. The only real trail is on the north side of the canyon, clinging to the steep slopes. I believe it was developed by mountain bikers, but it makes a fine route for hikers as well. I have found it best to hike up to the obvious ridge, then get on this trail for a scenic walk back down to the park. Even if you don't do this whole loop, a short hike part way up the slope will reward you with spectacular views of Mt. Rose, Slide Mountain, the Carson Range, and the expanse of the Truckee Meadows. Access to this area is through a gate at the mouth of the canyon, a short walk from the southeast corner of the horse arena.
