June 7 event features self-guided nature walks and activities for all ages.

(Orange County, Calif.) - Families and outdoors enthusiasts are invited to enjoy self-guided access in the magnificent Limestone Canyon at the fourth annual OC Parks Wilderness Celebration on June 7 from 8 a.m. to 2 p.m. Designated trails will be open for self-guided hiking, biking and equestrian use.

The Wilderness Celebration will offer self-guided access to trail routes of varying distance and level of difficulty within this open space preserve. "The Sinks" - an Orange County landmark formed over millions of years - will be accessible via a 9-mile round trip hike over moderate terrain. The 5-mile long Shoestring Trail Loop will also be accessible, with many other options for visitors of all ages to choose their own route.

The family-friendly event will include a children's interactive station with crafts, games and storytelling. This area will help kids learn about the wildlife and plant life found in Limestone Canyon and other local open spaces.

The annual Wilderness Celebration commemorates the gift of 20,000 acres of open space to the County of Orange in 2010. The land is part of nearly 40,000 acres of the former Irvine Ranch that has been designated as both a National and California Natural Landmark for its rare biological and geological features.

The day will begin with registration and trails opening at 8 a.m. Trails will be open for access until 1 p.m. Participants should note that for the safety of pets and preservation of local wildlife, dogs are not allowed in the Irvine Ranch Open Space at any time.

The fourth annual OC Parks Wilderness Celebration is free, and pre-registration is encouraged to save time on the day of the event. Information and registration is available at http://letsgooutside.org.
