NCAR Trailhead & Walter Orr Roberts Trail

NCAR scientists work on research topics in atmospheric chemistry, climate, cloud physics and storms, weather hazards to aviation, and interactions between the sun and Earth.
The NCAR facility is also the trailhead for a great system of trails in the Boulder foothills. The small Weather Loop trail, Walter Orr Roberts Nature Trail at NCAR features a system of signs describing weather phenomena along with a great view of the foothills and of Boulder itself. It's also a great spot to sight some of the local deer as well as a good variety of birds.
At the far end of Weather Trail is a trail that forms a junction to Mesa Trail and the trail system in the foothills behind NCAR. This is a popular walking/hiking area for Boulder residents. Mountain bikes are prohibited here and one should be mindful of both deer and bike riders on the road up to the NCAR parking area.

Comments |
The road to the trailhead is shared with residents and there are often bicyclists (and deer) on the road as it is a popular road to train on. Stick to the speed limit. |
