Directions for McDonald Observatory

McDonald Observatory, Texas


The Frank N. Bash Visitors Center is open 10 a.m. to 5:30 p.m. (additional hours on Star Party nights) every day except Thanksgiving, Christmas, and New Year's Day.

Visitors traveling east on Interstate 10 from El Paso may take Highway 118 south at Kent for the 39-mile scenic drive to the observatory. Remember that the Observatory is on Central Time (El Paso is on Mountain Time — one hour earlier than the Observatory).

Visitors traveling west on Interstate 10 may take Highway 17 south at Balmorhea to Fort Davis, then Highway 118 north 16 miles to Mt. Locke.

If you're coming from the Big Bend National Park, take Highway 118 north through Alpine and Fort Davis to the Observatory.
