Mesa Laboratory & Visitor Center

The National Center for Atmospheric Research (NCAR) sits nestled against Boulder, Colorado's famous Flatirons and the foothills of the Rocky Mountains. A working research laboratory, NCAR welcomes the public seven days a week to its Visitor Center, which offers educational exhibits, a guided noon tour Monday, Wednesday, and Friday except on holidays, and a tour using one's cell phone or MP3 players by request.  The Tree Plaza can be a pleasant place to enjoy a picnic. The Walter Orr Roberts Weather Trail and other scenic trails of varying difficulty can be accessed directly from the parking lot. Special public events are offered throughout the year, as are pre-arranged tours and field trips for schools, camps, clubs, and other groups of all ages and abilities.   

NCAR's flagship building was I.M. Pei's first major architectural design outside an urban setting. Take a virtual tour of the Mesa Lab's architectural development.
