NCAR’s Mesa Lab, located at the west end of Table Mesa Drive in Boulder, Colorado, is a working research laboratory that welcomes the public seven days a week. Admission is free. The building and the adjacent weather trail are both wheelchair-accessible. The inspiring setting is worth a visit in itself. We maintain the site as a nature preserve. Mule deer, fox, and other wildlife range over the area and adjoining mountain parks. NCAR’s laboratory offers a wealth of hands-on educational exhibits that visitors are welcome to explore on their own, on a tour, or with an audiotour.
