The Lima Peaks are a mountain range located in Dillon, Montana, USA.

Visual Characteristics

The Lima Peaks are characterized by rugged, granitic rock formations with elevations reaching over 9,000 feet. The slopes are covered in dense coniferous forests, primarily Douglas fir and lodgepole pine, transitioning to alpine meadows at higher altitudes. Snowpack is typically present on the highest peaks well into the summer months.

Location & Access Logistics

The Lima Peaks are situated approximately 15 miles south of Dillon, Montana. Access is primarily via Interstate 15 South, exiting onto Montana Highway 278 East. Continue on Highway 278 for approximately 10 miles, then turn south onto Forest Road 201. This gravel road provides access to trailheads and dispersed camping areas. Parking is available at designated pull-offs and trailheads; capacity varies. No public transport services reach the Lima Peaks.

Historical & Ecological Origin

The Lima Peaks are part of the Beaverhead Mountains, a sub-range of the larger Rocky Mountains. Their geological formation is primarily the result of Laramide orogeny uplift and subsequent erosion. Ecologically, they represent a transition zone between montane and alpine environments, supporting a diverse array of flora and fauna adapted to high-altitude conditions.

Key Highlights & Activities

Hiking is a primary activity, with trails such as the Lima Peaks Trail offering access to higher elevations. Wildlife viewing, including elk and bighorn sheep, is possible. Photography opportunities exist, particularly for mountain vistas. Backcountry camping is permitted in designated areas.

Infrastructure & Amenities

Limited infrastructure is present. Restrooms are available at the main trailhead for Forest Road 201. Shade is abundant within the forested areas. Cell phone signal is unreliable and generally absent in most areas of the range. No food vendors are located within the immediate vicinity of the Lima Peaks; visitors should bring their own supplies.

Best Time to Visit

The best months for hiking and outdoor activities are July through September, when snow has largely receded from trails. Mid-morning to late afternoon offers the most consistent lighting for photography. There are no tide-dependent activities.

Facts & Legends

Local folklore suggests that the peaks were once home to a reclusive prospector who discovered a significant gold vein but never revealed its location before disappearing. A specific tip for visitors is to be aware of rapidly changing weather conditions at higher elevations, even during summer months.
