After the sedentary pleasures of the Thanksgiving holiday -- turkey and TV football -- the East Bay regional parks stand ready to help you work off the extra calories.
Black Diamond Mines Regional Preserve in Antioch hosts its last mine open house of the season on Saturday, Nov. 24, at the Hazel-Atlas Underground Mining Museum. From noon to 4:30 p.m. visitors can take free, self-guided walks through 1,000 feet of restored 1930s-era silica sand mine.
For safety reasons, the mine walk is limited to ages 7 and older, though there is an underground chamber just inside the entrance where younger kids can hang out for some hands-on fun.
The mining museum will be open Sunday, Nov. 25, for paid guided tours. Then it closes until next March.
Black Diamond Mines is located at the end of Somersville Road, about five miles south of Highway 4 in Antioch. There's a parking fee of $5 per vehicle when the kiosk is attended. For information, call 888-327-2757, ext. 2750.
Naturalist Mike Moran continues his raptor population research with a bird-watching walk from 9 to 11:30 a.m. Thursday, Nov. 29, at Big Break Regional Shoreline in Oakley.
Anyone is welcome to join Mike, and no experience is necessary. The program is free, but registration is required. To register, call 888-327-2757. Select option 2 and refer to program 30694.
Children ages 3-5, accompanied by a parent, will enjoy a program from 10 to 11:30 a.m. Thursday, Dec. 6, at Shadow Cliffs Regional Recreation Area in Pleasanton, led by naturalist Katie Colbert. It's "Duck, Duck, Goose," a visit with our web-footed friends, of which there are plenty at Shadow Cliffs.
There's a fee of $6 per kid ($8 for nondistrict residents) and registration is required. Call 888-327-2757 and refer to program 30610.
Katie also hosts "Women on Common Ground," a series of programs for women who love the outdoors but have personal safety concerns. She'll lead a women's hike from 9 a.m. to 2:30 p.m. Saturday, Dec. 15, at Pleasanton Ridge Regional Park in Pleasanton. It's a five-miler to explore old olive groves, with an open house at Hillcrest Ranch.
The program is free; registration is required. For information, call 510-544-3243. To register, call 888-327-2757 and refer to program 30703.
