What is a weather trail?

The Walter Orr Roberts Weather Trail is a unique, self-guided tour that will introduce you to the weather and climate of NCAR's mesa location in Boulder as well as its plant and animal life. Installed in July 1997, it was inspired by a similar trail at the Swiss Meteorological Institute in Gstaad and is believed to be the first interpretive trail in North America devoted to weather and climate. This virtual version of the Weather Trail includes all of the text and imagery featured on the 11 signs of the actual trail.

The 0.4-mile (0.6-kilometer), wheelchair-accessible loop extends west from the Mesa Lab, at 1850 Table Mesa Drive in South Boulder. It includes a spur that connects to the Boulder Mountain Parks system just north of Bear Creek.

The trail features 11 viewpoints, each with a sign explaining a facet of the wild and varied meteorological conditions experienced in the Boulder area. The loop is about 0.4 miles (0.6 kilometers) long and features an elevation gain of roughly 74 feet (23 meters).

Signage for the trail was financed by Friends of UCAR, with support from the City of Boulder Mountain Parks, and developed by UCAR Communications and NCAR Visual Communications. The trail was constructed by Volunteers for Outdoor Colorado with support from Public Service Company of Colorado and the Boulder County Aggregate Resources Group.
