Groups of 10 or more reserving for a Solar Viewing, Tour, Twilight Program and/or Star Party receive automatic discounts (the reservation system will automatically calculate and apply the discount for you.)
No group discounts are available for Special Viewing Night (SVN) passes. SVN passes should be reserved separately from other reservations to ensure that important information about those programs is sent to you. See the SVN pages for more info.
Please include all members of your party in your tour reservation (including passes for children age 4 and under).Contact us for more information or to let us know if you have special needs. Bring a printout of your online receipt, a digital copy on your device (note that the Observatory does not have public WiFi and is out of cell range) or make note of the confirmation code you receive from our system. Passes will be under your last name at the Information Desk.
The system defaults to one adult pass. If you don't need that pass, click the number field and select zero.
If you're 65 or over and want the senior discount, choose the "Snr (65+)" pass only. There is no need to purchase both an adult and a senior pass.
Be sure to click on the "Book" button on the final reservations page as your final step in making your reservation.
