Navigating your adventure

As you plan your trip, check the CalTrans website and bookmark our Winter Road Closures page.

When it comes to parking, be prepared for less of it. Although there are less spaces to park, refrain from parking in the roadway. You can get cited or impede emergency traffic.

When it comes to maps, our "Eastern Sierra Winter Recreation Map" is a must-have! Download ahead of time, or get the Avenza app (Apple Store or Google Play) where you can navigate without the need for cell service.

Emergency preparedness

  • Rockslides and avalanches happen throughout the winter. Check the Eastern Sierra Avalanche Center often for the latest conditions, and learn how you can mitigate avalanche risk and get proper training.
  • Safe and proper use of winter gear such as ice axe and/or crampons is a matter of one's own blend of skills, experience and comfort zone.
  • Wilderness permits are still required.
  • Conditions can change rapidly depending on weather and time of day, and you are responsible for evaluating and determining If weather and conditions permit safe travel for yourself.
