Daytime Activities

The Visitors Center is open 12 p.m. to 5 p.m. Tuesday through Saturday. We are closed Sunday and Monday.

 

General Admission

General Admission provides access to the Frank N. Bash Visitors Center and the summits during regular daytime Visitors Center hours. In the Visitors Center, you can enjoy exhibits about our history, the science of astronomy, and the importance preserving dark skies. On Mt. Locke, you’ll be greeted by some of the most stunning views in Texas, and a small visitors gallery at the 107-inch Harlan J. Smith Telescope provides information about the science done there. On Mt. Fowlkes, you’ll be able to see one of the world’s largest telescopes, the Hobby-Eberly Telescope, from the George T. Abell Gallery.

General Admission is $3 per person. We strongly encourage you to purchase General Admission passes online to guarantee your access on the day of your visit. Please note that the Solar Viewing, Guided Tour, and Star Party include General Admission.
