How to Purchase Tour Tickets (online only)
Purchase your tickets online at recreation.gov or by phoning the call center at 1-877-444-6777. Tickets are available to purchase up to 14 days in advance. Tickets are released daily, starting at 8:00 am Mountain Time. (For example: Tickets for May 2 will be available starting April 18 at 8:00 am MT.)
Tickets will not be available for purchase in the park this year, so please plan in advance of your visit and purchase your tour tickets online. Tickets will likely sell out quickly, so you may want to get them as soon as they become available.
If you purchase a ticket and later decide not to go on the tour you have reserved, please modify or cancel your reservation using recreation.gov. Not only will you make those tickets available for other visitors, you will also receive a refund (minus the $1.00 reservation fee) if canceled up to 24 hours in advance.
