What to expect

You will be driven from our Mars Hill campus in Flagstaff to the LDT in Happy Jack, Arizona, while two of our knowledgeable educators give you the rundown on the history and the science of the area.

When you arrive at the LDT, our educators will give you a walking tour of the facility. You will learn the ins and outs of what it takes to maintain and operate a powerful 4.3-meter telescope, as well as how we use it to make groundbreaking discoveries about our universe. With a mirror larger than 14 feet across, this massive telescope itself is a sight to behold! Following your visit to the LDT, we’ll drive you back to Mars Hill where you can enjoy daytime tours and nighttime stargazing.

**NOTE: The LDT is a functioning research telescope; unexpected inclement weather or maintenance needs may occur at any time. Tours may need to be canceled on short notice in order to prioritize telescope repairs and the safety of our guests and staff.

Space on each tour is limited, so book your tickets to see the future of astronomical research today!
