The All-Year Highway is open and in good condition every day during the winter months and the Government maintains the roads in safe condition so that chains are not ordinarily needed. It is, however, advisable to carry chains in case they are needed during heavy storms. Information on snow sports and winter road conditions may be obtained at automobile associations. It is advisable to make reservations for rooms on Saturday nights and holidays from December 25 to February 25.

The Wawona Road to the Big Trees is open most of the winter except during periods of unusually heavy snowfall. There are unlimited snow fields for skiing and other snow sports along the Wawona Road, accessible through the tunnel.

The Valley, inclosed by granite walls which shut out the winds, has a mild and balmy winter climate. In fact, these walls really provide two distinct winter climates on opposite sides of the Valley, the north side being many degrees warmer than the south. On the northern side one may motor, ride horseback, and hike in comfort, while on the southern side, screened from the sun by the towering cliffs, all the popular winter sports prevail. Under the auspices of the Yosemite Winter Club, ice hockey matches, curling, fancy costume skating carnivals, snow figure contests, ski-joring races, skating gymkhanas, figure skating exhibitions, Eskimo dog races, and other winter sports events are held throughout the winter season, which usually lasts from December until March.

Competent instructors on the Yosemite Winter Club staff provide group and individual instruction in skiing and plain and fancy skating. Winter sports equipment and clothing may be rented reasonably in the Valley.

The National Park Service maintains a popular free snowslide for the enjoyment of the public. It is called “Ash Can Alley”, because the trip down the slide is made in heavy tin pans that resemble ash-can covers.

Skiing enthusiasts may enjoy excursions of several days’ duration in the high mountain country above Yosemite Valley accompanied by a ski instructor and guide and stopping overnight at ski lodges strategically located at an elevation where the snow is deep throughout the winter and in a region where the ski fields are second to none. Skiing is also enjoyed on ski fields along Wawona Road and adjacent to Glacier Point on the rim of the Valley, reached on foot over a 4-mile trail. The Glacier Point Mountain House is kept open during the winter season.
