Daytime Tours and Solar Viewings

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.

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

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.

Learn more about what to expect on the Daytime Programs ...

The Visitors Center operates a set of specially filtered telescopes equipped with HD video cameras that allow us to bring live, safe views of the Sun into our theater. Knowledgeable guides will discuss the history of the Sun, its formation, and what we expect the Sun to do over its expected 5-6 billion year remaining "lifetime". Your guide will use the telescopes' remote controls to view the Sun and various surface features typically visible. On not so clear days, video and stills are used. This is typically a 45-50 minute program.

The guided tour begins at the summit of Mt. Locke. Visitors may drive their vehicles or ride in the Observaotry shuttle (limited capacity). Guides provide some history of the Observatory and the large telescopes onsite, including descriptions of the parts of the telescope, demonstrations of the telescope motions, etc. The tour continues to the summit of Mt. Fowlkes and the Hobby-Eberly Telescope (HET). At the HET, you'll learn more about that telescope's unique design and the current cutting-edge research done here.

The programs described here are our typical daytime activities. However, research constraints will sometimes force us to alter the content somewhat. Additionally, visitation during certain times of the year (specifically, Spring Break) forces us to reorganize the tour content. While the Solar Viewing will take place much as described above, the content of the 107" tour will take place in somewhat altered order and the Hobby-Eberly Telescope will be self-guided only.

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.)

Learn more about what to expect on the Self-guided Tour ...

Some areas of the Observatory are accessible without a guide. A brochure is available at the Information Desk ($1 donation suggested or download the PDF here before you head out.) At the top of Mt. Locke, the views off to the east, south, and southwest can be stunning on a clear day. The booklet can fill you in on some of the history and contributions of the large telescopes at this peak. Restrooms are available at the 107" dome from 10:00a - 5:00p everyday. There are also several informative short videos available for view in the ground floor lobby of the 107" dome. Currently, no other part of the 107" dome is accessible to the public except on the guided tour. The 82" dome is not accessible to the public.

Over at the summit of Mt. Fowlkes, you can see the largest telescope in North America and the 5th largest in the world .. the Hobby-Eberly Telescope (HET). Available from 10:00a - 5:00p at the George T Abell Gallery, informative videos run continuously as part of an exhibit explaining a major new project being conducted at the HET ... the Hobby-Eberly Telescope Dark Energy Experiment or HETDEX, for short. Public restrooms are also available in the HET gallery. A large panoramic window gives you up-close views of this unique telescope.

SBCGlobal, AOL, Yahoo, HotMail, etc.: SCBGlobal customers ... SBCGlobal appears to be completely blocking email from our reservation system. Either use a different email address or send an email to our staff who can send you a PDF copy of the confirmation. We've had a number of visitors with AOL, Yahoo, HotMail sorts of email accounts tell us that they've not received their purchase confirmation emails. Apparently, these services aggressively filter for spam and our confirmations are getting caught in these filters. Please be sure to check your spam/junk folder and/or add "reservations@webreserv.com" to your address book as an approved email contact before making your reservations to avoid missing your confirmation email.

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.
