Group Tour Payment Information
All group tours require a non-refundable deposit of 50% of the total group price. In order to guarantee staffing for group tours, all deposits are due upon receipt. Final payment must be made online or on site at the start of your group’s scheduled tour time.
Note: Observatory access may be closed to the public during rain, dangerous weather or high humidity. The stair access to the observatory is narrow with low clearance and requires “off trail” coordination. High heels are prohibited. Please contact to guarantee access is available the day of your tour if in doubt due to the weather.
