Closed Ski Area
Hidden Valley Ski Area

Rocky Mountain National Park
Estes Park, Colorado


Hidden Valley Ski Area is now closed. The lifts have been removed. What is left are fantastic runs for the backcountry enthusiasts.
Rocky Mountain National Park has a visitor center and just past the visitor center is where you will need to pay an entrance fee. To see current park entrance fees, please see RMNP Entrance Fees.
Hidden Valley ski area opened in 1955 and closed as a ski area in 1991. The lower area of the valley, below Trail Ridge Road is great for beginner and intermediate skiers/boarders. Above Trail Ridge road is where you find the expert runs. Trail Ridge Road is closed in the winter from roughly November to May or June.

Warning!!! This old ski area does not have a ski patrol, it does not have avalanche control, it does attract backcountry skiers, some of whom do not know very much about avalanches. Please do not ski this area without the proper gear and knowledge. Do not imitate other skiers, as they may have been lucky that a slope did not slide, and you may not be so lucky. The BOC rents backcountry gear including safety gear. The BOC also offers avalanche level 1 certification. Please be prepared before you play on at this area.
The runs rated easy and moderate will be less prone to avalanche danger and can be great for intermediate skiers/boarders.
