Scots will bring the Highland fling and other aspects of their culture to Ardenwood Historic Farm in Fremont on April 6 for the annual Tartan Day Scottish Fair.

From 10 a.m. to 5 p.m. there will be Scottish music and dancing, bagpipe performances, handmade crafts for sale, historical re-enactments and Highland athletic competitions.

Local Scottish clans and societies will share their heritage, kids will enjoy the Children's Glen and Scottish food will be available. Kilts are not required, though you will not be alone if you wear one. It's always a colorful, friendly and fun event.

Ardenwood is located at 34600 Ardenwood Blvd., just north of Highway 84. Entry fee for the fair is $12 for adults, $8 for seniors ages 62 and older, $5 for children ages 4 through 17 and free for ages 3 and younger. Parking is free. For more information, call 888-327-2757, ext. 2797.

even more wildflowers: Ohlone Regional Wilderness is another great wildflower venue, with an often-spectacular display up on Rocky Ridge. To get there, start at the Lichen Bark picnic area in Del Valle Regional Park south of Livermore. From Lichen Bark, hike 21/2 miles uphill on the Ohlone Wilderness Trail. Be advised, this is a strenuous, long and sometimes steep climb. But the flowers and the view are worth it.

Del Valle Regional Park is on Del Valle Road off Mines Road about 6 miles south of Livermore. There's a fee of $6 per vehicle, and you must also purchase a permit to hike the Ohlone Wilderness Trail. Permits cost $2 per person older than 13 and are good for a year. They are available at the park entrance kiosk.

Women on Common Ground is a series of naturalist-led hikes for women who enjoy the outdoors but have concerns for personal safety. The hike is free, but registration is required. Call 888-327-2757, select option 2 and refer to program 1699. Or visit www.ebparksonline.org.
