Most people consider a conversation about the weather to be a desperate attempt at small talk. But at the National Center for Atmospheric Research, sun, rain, wind and snow are always important topics. At this stunning sandstone building atop Table Mesa – a landmark some might recognize from Woody Allen's film, "Sleeper" – scientists study weather-related phenomena such as ozone depletion and the greenhouse effect. On a visit to the center, you can see some of the tools used to conduct experiments, like weather balloons, satellites and even robots. Meanwhile, hands-on exhibits are sure to excite the budding meteorologist in your family. After you've sufficiently toured the complex, get some fresh air along the Walter Orr Roberts Nature and Weather Trail, where you can learn all about Table Mesa's wildlife.

Guided tours of the center are available on Monday, Wednesday and Friday between noon and 1 p.m., and recent visitors recommend coming prepared to learn as knowledgeable tour guides are eager to answer your questions. You can also opt for a tablet or cellphone tour; whichever option you choose, travelers highly recommend taking some time to explore on your own before grabbing a snack and enjoying the view from the on-site cafeteria.

The National Center for Atmospheric Research is open to visitors Monday through Friday from 8 a.m. to 5 p.m. and on weekends from 9 a.m. to 4 p.m. Admission to the center and guided tours are free. The center is located about 15 minutes south of downtown Boulder; a car is the best way to get here. For more information, check out the center's website.
