A Place with Ski History

Hidden Valley was once a developed ski area inside the national park.

Open slopes remain visible

The broad hillside and developed recreation area still reflect the site's former use.

05 · JUNIOR RANGER HISTORY

Former seasonal program use

The Hidden Valley facility has also been used for Junior Ranger programming during summer seasons.

06 · STEWARDSHIP

Recreation continues with limits

Modern rules concentrate snow play in a designated area to improve safety and reduce resource impacts.

Winter Sledding

The park's only designated sledding hill.

Snow conditions can be poor even in winter, so check current NPS updates before driving up.

Stay inside the boundary

NPS requires sledding and tubing to remain within the posted Hidden Valley Snow Play Area.

There are no sled rentals inside the park. Metal-runner sleds are not allowed.

Plan how to stop

NPS advises sledders to have a plan for slowing and stopping and recommends sledding feet-first.

05 · OTHER USERS

Share the slope carefully

Skiers, snowboarders, and snowshoers may pass through and must slow down and yield to sledders.

06 · UNSTAFFED AREA

Sled at your own risk

The sledding hill is generally unstaffed, although rangers or volunteers may occasionally be present.

Picnicking and Facilities

Use established facilities and pack out everything you bring.

Flush restrooms

NPS states that flush restrooms are open daily near the bottom of the sledding hill and parking area.

Leashed pets are permitted in established picnic areas, but pets are prohibited on trails, tundra, meadows, and the Hidden Valley sledding hill.

04 · FIRES

Use only designated grates

NPS permits campfires in designated picnic-area metal grates when current restrictions allow; collecting firewood is prohibited.

05 · FOOD

Prevent wildlife conflicts

Never leave food unattended, and remove scraps and trash after eating.

06 · TIMED ENTRY

Park-entry rules still apply

When timed entry reservations are required during designated hours, they also apply to accessing park picnic areas.

Hiking and Snow Travel

Conditions determine the experience.

Even short outings require appropriate footwear, layers, and awareness of changing weather.

Backcountry-style winter travel

Skiers may use appropriate areas but must avoid interfering with the designated sledding hill.

Check before leaving

NPS trail reports note that conditions can change rapidly and may be better or worse than the latest report.

Look up

NPS warns that falling trees and branches are a year-round hazard in forested areas.

06 · AVALANCHE AWARENESS

Know the terrain

Winter visitors heading beyond developed snow-play areas should review current avalanche and snow-depth information.

Mountain forest species

Chickadees, jays, woodpeckers, and other birds use the surrounding forest.

06 · ROADSIDE VIEWING

Park safely

Use designated parking and pullouts rather than stopping in a travel lane for wildlife.

Photography

Forest, snow, and recreation history create a distinctive visual setting.

Use legal parking and avoid interfering with other visitors or wildlife.

Fresh snow can transform the former ski slopes into simple high-contrast compositions.

Road access, snow depth, recreation options, and facility use are seasonal.

Patchy snow and mud

Sledding conditions deteriorate as snow melts, while trails and picnic areas transition toward summer use.

FALL

Cool weather returns

Freezing nights and early snow can arrive before consistent winter conditions.

WINTER

Sledding season
