Argentine Pass and McClellan Ridge OHV Trail

This trail is rated as difficult for hikers due to its high elevation, significant elevation gain, and rocky, unimproved road conditions. The highest point, Argentine Pass, reaches over 13,200 feet. Hikers should be prepared for strenuous sections, steep ascents, and large rock obstacles, especially as you gain elevation.

The terrain is predominantly rocky, becoming particularly narrow and challenging towards the top of Argentine Pass. You'll encounter creek crossings, switchbacks, and sections that follow old, converted railroad beds. While primarily an OHV trail, it offers a rugged hiking experience with varied surfaces.

The best time to hike this trail to reach the summit is typically between July and September. Snow can block the trail well into the summer, even at 12,300 feet in June, making it impassable or very challenging. Early season water crossings can also be deep.

The trail starts right outside Georgetown, Colorado. A common access point is the Silverdale Trailhead. Parking is generally available at designated areas near the trailhead.

You'll be treated to awe-inspiring Colorado Mountain vistas, including spectacular views of multiple fourteeners and Peru Creek from Argentine Pass. The trail also features aspen groves (especially beautiful in the fall), waterfalls, and significant historical mining sites like the Waldorf and Santiago Mines, where you can explore old structures and ghost town features.

The trail is generally dog-friendly, but dogs should be kept on a leash. For families, the strenuous nature, high elevation, and rocky terrain make it less suitable for young children or beginner hikers. The lower portions might be more manageable, but the full ascent to Argentine Pass is a significant challenge.

The Argentine Pass and McClellan Ridge OHV Trail is located within the Arapaho National Forest. Generally, there are no specific permits or entrance fees required for day hiking on this trail. However, always check the latest regulations from the US Forest Service before your visit, especially for dispersed camping or specific activities.

Yes, the route also passes through sections of the Argentine Central Railroad Grade Trail, the Clear Creek Greenway, and the ADT - Colorado C - Q - Seg 4. A small portion also overlaps with the CDT - Colorado Section and Leavenworth Creek Road.

From the Waldorf Mine site, hikers have the option to continue towards Argentine Pass or head up McClellan Mountain, both offering unique views. The trail itself is primarily an out-and-back route, though some sections might allow for variations or connections to other trails.

The full hike, covering a distance of approximately 24 kilometers (15 miles) with over 1,400 meters (4,600 feet) of elevation gain, typically takes around 7 to 8 hours to complete. This duration can vary significantly based on your fitness level, pace, and time spent exploring historical sites or enjoying viewpoints.

The trail starts right outside Georgetown, a quaint historic town. In Georgetown, you can find various amenities, including cafes, pubs, and accommodation options. Dispersed camping opportunities are also available along sections of the trail itself.
