Overview

The Ron Stewart Preserve at Rabbit Mountain is a 4,900-acre protected area in Boulder County, Colorado, known for its unique location at the transition zone between the Great Plains and the Rocky Mountain foothills. The preserve features a network of multi-use trails that traverse grassland, shrubland, and ponderosa pine forest ecosystems. Wildlife observation is a primary activity, with the area hosting populations of mule deer, elk, black bears, and various raptors. The Eagle Wind Trail offers a moderate loop that provides sweeping views of the Continental Divide and the surrounding plains. Geologically, the area is characterized by the prominent hogback ridge that gives the mountain its name. It serves as an important habitat corridor for wildlife migration. The preserve is managed by Boulder County Parks and Open Space with a focus on ecological restoration and conservation. Visitors can expect rugged terrain with minimal shade on the eastern slopes.

Insider tips

Bring binoculars as this is a prime location for spotting golden eagles and other birds of prey.

Check the official Boulder County website for seasonal trail closures due to elk calving or weather conditions before heading out.

Carry significantly more water than you expect to need, as the high-altitude sun and lack of shade lead to rapid dehydration.

What to avoid

Do not attempt to hike during midday in the summer months as there is very little natural shade and temperatures can be intense.

Good to know

Portions of the trail system, particularly the Indian Mesa Trail, are frequently closed seasonally from February through June for elk calving.

Etiquette

Stay on designated trails to protect sensitive habitat; dogs must be on a handheld leash at all times; leave no trace.
