Tioga Road

Plows have reached Tioga Pass. Plowing of side roads, turnouts, parking lots, etc., are in progress. Additional work, including road repairs, removal of trees that may fall onto the road, utility system repair, etc., must all occur prior to road opening. There is no estimated opening date for Tioga Road.

If the road opens to bicycles before it opens to cars, an update will appear here.

The road normally reopens in late May or June.

Glacier Point Road

Glacier Point Road opened on Friday, April 30, at 8 am.

The Glacier Point Road normally opens to vehicles sometime in May.

Glacier Point Road will be closed to all traffic in 2022 to rehabilitate and improve the road. The only access to Glacier Point will be via the Four Mile, Panorama, and Pohono Trails, all of which are strenuous hikes.

 
Answers to Frequently Asked Questions:
  • Road repairs, ditching, and brushing operations must occur once snow has melted back enough. The roads may also remain very icy even after they're plowed.
  • 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 if they are closed to vehicles.
