A Laguna Beach author will sign copies of her new guidebook about Orange County hiking trails at Crystal Cove State Park on Saturday.

Karin Klein, author of "50 Hikes in Orange County," will sign copies at the Store (Cottage No. 45), in Crystal Cove's historic cottage district near the Beachcomber Café, according to a news release. Proceeds from the 9 a.m. to 2 p.m. event will go toward the Crystal Cove Alliance, a nonprofit that supports the state park.

Klein works as an editor at the Los Angeles Times. She also serves as a tidepool docent at Crystal Cove State Park and as a volunteer naturalist at Laguna Coast Wilderness Park, Caspers Wilderness Park, and Aliso and Wood Canyons Wilderness Park.
