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.
