Sugarloaf Ridge was one of the first parks to close under the California State Parks plan to close up to 70 of its 278 parks due to budget cuts. The closures were deemed necessary to achieve an $11 million reduction in the next fiscal year 2011/12, that amount increasing to $22 million in the following fiscal year 2012/13. The park was reopened by Team Sugarloaf in June 2012 to restore access to camping and hiking trails. The park's official address is 2605 Adobe Canyon Road, Kenwood, CA 95452. History The Onasáti (Wappo) were the first known inhabitants of the region, settling on along the Sonoma Creek 1500 years ago. They relied on various resources of the region especially acorns and berries, and are known for their farming and basketry abilities. Spaniards attempted to takeover the area in 1823, failing. Later, the cholera epidemic dwindled the numbers of the Wappos, who were ultimately relocated to Indian reservations by the American government. In the 1870s farming increased in the Sugarloaf region. Business owners in town began hiring "gentlemen farmers" to manage their ranches along the Sugarloaf Ridge while the business owners remained in the town. Some even made livings off burning trees of the Sugarloaf region to make and sell charcoal. By 1920, the California government had dammed the creek for public water use while the region attracted campers, picnickers, and Boy Scout troops. Land owners began leasing land for animal grazing in 1942. Finally in 1964, the state of California admitted Sugarloaf as a California State Park.
