Rocky Mountain Arsenal National Wildlife Refuge Perimeter Trail

The Rocky Mountain Arsenal National Wildlife Refuge Perimeter Trail offers a unique gravel biking experience, transporting you from urban fringes to a thriving prairie ecosystem. You'll traverse wide, non-technical gravel paths, passing wetlands and grasslands, with frequent opportunities to spot bison, deer, and raptors. The route provides open vistas and even a distant view of Downtown Denver from Henderson Hill, making it a rewarding journey through nature.

This moderate 27.0-mile (43.4 km) loop involves a manageable 439 feet (134 metres) of elevation gain, taking approximately 3 hours and 57 minutes to complete. Remember to bring all your water, as none is available on the trail, and consider tubeless tires (40mm or wider) to guard against goat's head weeds. Dogs are generally not allowed within the main refuge area.

This trail is a testament to conservation, transforming a former toxic site into a vibrant wildlife sanctuary home to over 330 species. It's an excellent choice for beginner gravel biking or as a training route, offering a long, relatively flat ride where the primary challenge is the distance and potential for varied terrain conditions.

The Carbondale loop via Rio Grande Trail offers a challenging and scenic gravel biking experience through the Roaring Fork Valley. You'll traverse a mix of asphalt and compacted gravel, with significant climbs that lead to breathtaking views of the Roaring Fork River and the iconic Mount Sopris. It's a demanding 46.7-mile (75.2 km) journey that truly showcases the region's natural beauty.

Rated as difficult, this loop involves a substantial 4039 feet (1231 metres) of elevation gain and typically takes around 5 hours and 52 minutes. It requires very good fitness, so plan accordingly. Starting from Carbondale, ensure you're well-prepared with water and supplies, especially during warmer weather, as the full loop extends beyond the gentler sections of the main Rio Grande Trail.

This route is a highlight for gravel enthusiasts, combining the historic rails-to-trails corridor of the Rio Grande Trail with more rugged dirt roads. It acts as a cycling spine for the valley, connecting communities and offering a rich mix of Colorado's diverse landscapes. The varied terrain, including "Colorado Champagne gravel," makes it a rewarding adventure for those seeking a demanding ride.

The View from Chatfield Dam – South Platte Reservoir loop from Littleton - Mineral offers a dynamic gravel biking experience, winding through diverse terrain from chunky gravel to smooth dirt. You'll enjoy panoramic views of the Chatfield Reservoir from atop the dam, with the Front Range foothills as a stunning backdrop, and pass by smaller lakes like Eaglewatch, Redtail, and Blackrock. The route provides a mix of open plains, river valleys, and wetlands, often described as brilliantly green and lush in spring, making for a constantly engaging ride.

This moderate 36.5-mile (58.8 km) loop, with 1251 feet (381 metres) of elevation gain, typically takes around 3 hours and 47 minutes to complete. As it's within Chatfield State Park, be aware of potential park entrance fees. For the best experience and to prevent flats from goat's head weeds, consider using at least 40mm wide tires, ideally tubeless with sealant. Parking is available within the park, but arriving early is advisable during peak times.

This trail is a key part of an extensive network, connecting to major systems like the Colorado Trail, Waterton Canyon, and the High Line Canal. The area is a haven for wildlife, with sightings of deer, bighorn sheep, and various bird species common, especially along the South Platte River. The Chatfield Dam itself is an interesting engineering marvel, offering unique viewpoints and a glimpse into the region's history of flood control and restoration.

December 9, 2025, View of Downtown Denver from Henderson Hill

The Henderson Hill trail is a short out and back paved trail to a low rise in old Rocky Mountain Arsenal area, now a wildlife refuge. Even though the difference in elevation is minimal the view is far reaching to the east and south. You can actually reach this spot using only bikepaths (route5) from Commerce City. See this ride https://www.komoot.com/tour/2710436405?share_token=aTyj2lJ1YHiQOhPskXyq8prHxb5AoOId67IJs0FNb2tJwCStGp&ref=wtd. The way that this ride got around the east side of the refuge is not recommended though.

This trail runs through the valley along the Eagle River and I-70 corridor. It connects many towns and parks and offers great views along the way. It is a paved, multi-use path, so be courteous to your fellow trail users who may be going along at a slower pace.
