Interstate 10 is the Highway to the Stars. Almost all of the largest optical telescopes in the continental United States, as well as the world's most powerful radio telescope, lie within  two or three-hours of the highway.

The optical telescopes all stand on mountaintops, which provide clear views of the sky. These remote outposts also offer spectacular views of both Earth and sky for the hundreds of thousands of visitors who drop in each year.

All of the major southwestern observatories offer special programs for visitors, including museums, tours, and star parties. Each is worth a side trip from the Interstate.
