The McDonald Observatory is not a Federal facility and is therefore not affected by the current government shutdown. The Visitors Center remains open for regular business and all previously scheduled programs will be offered.
All programs are subject to capacity limits. Solar Viewings and Guided Tours frequently sell out during busy periods such as holidays and Spring Break. To ensure program participation, make advance reservations using the online system below.
Join a Guided Tour for an up-close look at large research telescopes at McDonald Observatory in West Texas.
A Daytime Pass includes access to the exhibit gallery inside the Frank N. Bash Visitors Center, the Solar Viewing Program (typically 45-50 minutes) in our theater featuring live (weather dependent) telescope images of the Sun, and a guided tour (approximately 90-100-minutes) of our large research telescopes. Daytime passes may be purchased online (assuming availability) until midnight before the program. Check the calendar for program offerings and start times.
Don't have time for the Guided Tour but still would like to see an up-close, live view of the Sun? Passes for the Solar Viewing-only may also be purchased for those who may be on a tight time-schedule.
Self Guided Tours of our largest telescope, the 362-inch Hobby-Eberly Telescope, are available at no charge from 10 a.m. to 5 p.m. daily. (See the drop-down text below for more information on what parts of the facility are available to the public.)
The system defaults to one adult pass. If you don't need that pass, click the number field and select zero.
If you're 65 or over and want the senior discount, choose the "Snr (65+)" pass only. There is no need to purchase both an adult and a senior pass.
Be sure to click on the "Book" button as your final step in making your reservation.
Our Spring Break 2019 schedule is now posted! If you're visiting from March 9th thru the 23rd, please see this expanded schedule of programs (not the schedule below.)
