Tioga Road

May 16, 2017 (updated about twice per week)
Plows ended one mile west of May Lake. Crews are progressing from west to east about one mile per day as they plow through snow that is 8 to 10 feet deep.

Forestry crews have begun removal of hazard trees (dead or diseased trees that might fall onto the road) between Crane Flat and White Wolf, and in the Crane Flat Campground.

Glacier Point Road

May 10, 2017
The Glacier Point Road opened for the season on May 11 at 9 am. Check the current conditions page for its current status.

Trails from the Glacier Point Road are very snowy; hikers will need cross-country navigation skills using a map and compass, as well as snowshoes or skis.

  • Due to snow pack, trails along Glacier Point Road lose their definition. Every year, hikers become lost. Conditions this year are even worse than past years.
  • As always, leave your hiking plan, including route, destination, and return time with a trusted person. Leave another hiking itinerary in the glove box of your vehicle.
  • Hiking the Glacier Point area means hiking in winter travel conditions and anyone who hikes it should have good wayfinding skills including a suitable topo map and compass (GPS optional).
  • Following footprints in the snow or rock cairns is risky; they may belong to someone else—who also got lost.
  • Always pay attention to your return route and alwaysbe able to return from the way you came.
  • The Four Mile trail remains closed approximately half way up due to ice sheets.
Answers to Frequently Asked Questions:
  • Avalanche zones (26 potential areas). The Olmsted Point avalanche zone requires careful work, including application of charcoal over the snow to help with melting and blasting the snow slab to make it safer for personnel.
  • Heavy snow pack slows the whole operation.
  • Trees that have fallen across the road and been buried in the snow can cause substantial damage to equipment and result in a stop to all operations until they're cleared.
  • Rockfalls buried by the snow can cause substantial damage to the equipment and result in a stop to all operations.
  • Snow storms during the opening require a stop to Tioga Road operations in order to plow and sand park roads that are open.
  • Will I be able to ride a bicycle on the Tioga or Glacier Point Roads before they open to cars?
    In some years, these roads may be open during limited periods to bicycles prior to opening to cars. Any updates regarding pre-opening access on these roads will appear on this webpage. Unless otherwise posted here, both roads are closed to cyclists.
