The building is beautiful. To understand the architecture helps understand the science. The free Saturday tour is wonderful. (A $5 per person donation is suggested, and well worth it.). We did that, and also paid for a nightly group viewing session for $30 each. Wow, Dan knows his stuff. We viewed the moon, Saturn, and other celestial objects over several... More

Live in Wisconsin more than 25 years but never have a chance to check out this place. Yesterday, a friend invited me to join them for a day trip to William's bay, and I check out this attraction. The tour is good, the architecture is interesting even it was not the best. Recommend to check out the George William college,... More

Our son-in-law suggested a day trip to William's Bay and Lake Geneva. He knows I like architecture so recommended that we check out the observatory. Sadly we had missed the last tour, go early if you want a guided tour. However, the very friendly volunteers and staff let us in to look at the main entrance foyer and gave us... More

This place is definitely worth one's time, but the tour focuses more on the building's architecture and history than on the science/technology side. So, if you're a science geek, you may be somewhat disappointed in the Sat. public tours. Try the other options with costs but views.

I recently viewed a dvd about the Hubble telescope and they began at the beginning which included one man's passion (George Hale) and another man's pride (Charles Yerkes) If you are in the area, this place is worth a visit. The grounds are beautiful. The building is covered with many unique architectural forms. Volunteers with a passion for their subject... More

Having been a science teacher with a specialty in astronomy, I have a keen interest in observing instruments. The 40 inch refractor at Yerkes was, and is, the largest refracting telescope in the world. When it opened, it was an important scientific instrument. Sadly, technology has long since passed it by. That it is still there and kept up is... More

Yerkes is worth a visit for their tours on Saturday mornings, or just to take a walk around the building and grounds. Pay close attention to all of the details on the building. I have been on the tour many times and it is never the same twice. I visit the building and walk around the grounds nearly every time... More

I came for the building, husband came for the science, we both left smiling. The guide was a wonderful retired professor and he moved the dome and the telescope and the floor to show us what marvels they were in 1895 and what marvels they still are today. Tours on Saturday only - don't miss this!!

Took my first tour as a kid and recently returned. Beautiful grounds and architecture. Informative, interesting Saturday morning tours. Nice way to learn more about history, astronomy and architecture. Impressive to see the inner workings of a large observatory. Definitely worth the time to visit when in the area on Saturdays. A nice spot for a quick walk and some... More

This was an interesting tour. Much great information about the decision of why the telescope was there, who's idea it was, who funded it, etc. Some of the information was old, and not accurate (scripted). The guide that brought us up to the telescope seemed more interested in selling us a picture of Einstein at the telescope than anything else,... More
