Welcome to Lowell Observatory's online private program scheduling service!

Each year, we welcome more than 8,000 people in over 300 different groups to our campus for private programs. Families, school groups, and other organizations come here to learn about astronomy and view the night sky. Because of increasing visitor volume, and to allow you to reserve programs 24-7, we have created this online booking service. Use this site to pick the date and time of your visit, and the programs you would like to see. Reservations must be made at least three weeks in advance of the chosen program date.

PAYMENT POLICY: Group sizes are limited to 60 people, and programs must be booked three weeks or more in advance. The fee is $70 (for one-hour daytime programs) or $150 (for 90-minute evening programs). Payment must be made in full at least one week in advance of your program date to hold your reservation. We do not accept purchase orders. Payment includes a $20 non-refundable processing fee. For futher information, please read the Program Reference and Payment Policies.
