Clear Lake is California's largest natural freshwater lake, in Lake County about 110 miles north of San Francisco. The lake and the surrounding hills have a relaxed, old-fashioned resort feel that is a world away from the Napa Valley wine corridor to the south — fewer tourists, lower prices, and a genuine outdoors culture.
The lake is known for its bass fishing, which draws serious anglers year-round. Swimming, boating, and water-skiing are popular in summer. The county's six wineries produce decent wines in a more casual atmosphere than Napa — Fetzer Vineyard has its roots here. The area around Kelseyville has old pear and walnut orchards, and the local Bartlett pears are worth seeking out in season.
Lake County also has a volcanic history — Clear Lake sits in a volcanic basin, and the geothermal area around Cobb Mountain to the west produces natural hot springs. The Pomo people have lived around the lake for thousands of years and the Lake County Museum in Lakeport has a good collection of their basketwork.
