The Coney Buchanan loop is a demanding mountain biking route near Ward, Colorado, that immerses you in the stunning scenery of the Indian Peaks Wilderness. You'll navigate through dense forests, open wetlands, and expansive meadows, with opportunities to spot wildlife like moose. The trail itself is a blend of technical singletrack and rugged 4x4 roads, offering a challenging ride with rewarding views of Beaver Reservoir and distant peaks.

This 10.2-mile (16.4 km) loop, rated as moderate, involves a significant 1220 feet (372 metres) of elevation gain and typically takes around 1 hour and 40 minutes. It's best suited for experienced riders comfortable with rocky, steep terrain. While mountain biking is allowed, be prepared to share the path with hikers and off-road vehicles, especially jeeps on the 4x4 sections. Riding early in the morning or during the shoulder seasons can help you avoid the busiest times.

What makes the Coney Buchanan loop stand out is its combination of technical challenge and diverse, beautiful landscapes. It provides access to the renowned Indian Peaks Wilderness, known for its alpine wildflowers and dramatic Rocky Mountain vistas. The trail can be ridden year-round, transforming into a fatbiking adventure in winter, though some sections may be untracked after heavy snow.

Prepare for a demanding mountain biking adventure on Rollins Pass Road, a difficult 27.5 miles (44.2 km) route that climbs through the Arapaho and Roosevelt National Forests. As you ascend, you'll navigate past conifer trees and impressive granite walls, eventually breaking out above the treeline. This challenging ride involves gaining 2781 feet (848 metres) of elevation, typically taking around 4 hours and 25 minutes to complete. You'll experience high-alpine scenery, passing landmarks like Yankee Doodle Lake and Jenny Lake. From the 11,676-foot summit, expansive views of the Indian Peaks and James Peak wilderness areas await you.

Before you set out, be aware that Rollins Pass Road is rated as difficult, often compared to a 'black diamond' trail. You should be prepared for rocky and muddy sections, especially if you plan to mountain bike the entire route. Some parts, particularly near the Needle's Eye Tunnel, might even require you to carry your bike. Always be ready for rapidly changing weather conditions in the high altitude; snow can occur even during summer months.

Beyond the natural beauty, Rollins Pass Road offers a journey through history. The route features fascinating historical remnants, including the unique Needle's Eye Tunnel. You will also encounter the thrilling Trestle Bridge, a significant structure at Rollins Pass.

The Sourdough and South Saint Vrain Loop offers a relentless technical mountain biking experience through high-altitude pine and aspen forests. You'll navigate a challenging 18.0-mile (29.0 km) route, gaining 2301 feet (701 metres) in elevation over approximately 3 hours. Expect a ride filled with rocks, roots, and demanding sections often described as "boulder gardens" and "watermelon patches," particularly on the South Saint Vrain Trail. This trail is a true test of skill and endurance, winding through shaded woods with glimpses of mountain prairies and potential wildlife sightings.

Planning your visit requires acknowledging the trail's demanding nature; it's rated moderate but is considered difficult to very difficult by many riders. The continuous technical challenge and sustained climbing at altitudes between 9,200 and 10,200 feet mean less experienced riders should expect to dismount frequently. The ample shade makes it a good option for riding on hot summer days, and it's also a popular spot for fat biking in winter, offering a different kind of challenge when snow covers the terrain.

This loop is notable for its backcountry feel and its ability to hone technical riding skills, making it a favorite among advanced mountain bikers. While the Sourdough Trail offers its own Black Diamond sections, the South Saint Vrain Trail is often considered Double Black Diamond, requiring significant effort and focus.
