As a wildlife sanctuary, Thomas F. Riley Wilderness Park is home to an abundant number of native plants and animal life. Old groves of Western Sycamores and Coast Live Oaks border the park's two seasonally flowing creeks. The remaining land features rolling hills and canyons of Coastal Sage Scrub and grasslands.
This 544 acre wilderness park has five miles of multi-use and single track trails offering outdoor enjoyment for hikers, equestrians and mountain bikers. Ranger-led programs as well as self-guided hikes provide opportunities for the visitor to learn about the richness of this sanctuary. The park's outdoor "classroom" atmosphere offers students of all ages, scouts and other youth oriented organizations, a place to experience firsthand, the intricate relationships between the park's wildlife and habitat, offering an opportunity to work on outdoor projects and fulfill classroom requirements.
Parking is available for 50 vehicles including horse trailers. For equestrians, there are 4 pipe corrals and a watering fountain. Other amenities available are picnic tables, portable restrooms, drinking fountains and handicap access to the visitor center.
The Ranger Station houses a hands-on classroom and a variety of interpretive displays which highlight the park's wildlife and history. Surrounding the station is a one acre native plant butterfly garden, a large deck for picnicking and enjoying the views, and informational bulletin boards.
OC Parks is pleased to introduce new parking passes that will allow visitors to use a single card to park at all County regional and wilderness parks and/or beaches.
The new “smart cards” replace the entry cards and stickers that were previously used for annual parking. Unlike the previous OC Parks passes, which were fixed to a calendar year (January through December), these smart cards are valid for 12 months from issue date and can be renewed annually. Moreover, for wilderness and beach locations which previously required a sticker affixed to a visitor’s windshield, these passes can be used with any vehicle. The price for the new cards remains the same as 2014.
The clocks fall back early Nov. 2, marking the end of daylight saving time and OC Parks’ spring-summer operating schedule. Wilderness parks close at sunset and most regional parks close at 6 p.m. for the fall and winter.
