Chatfield Reservoir and High Line Canal Loop

This loop offers a varied cycling experience, often described as a "mixed-terrain adventure." You'll encounter a mix of paved sections, crushed gravel (both smooth and chunky), old cracked asphalt, and even some rutted dry mud/sand. Be aware that the approximately one-mile stretch across the Chatfield Dam consists of sharp gravel, which is not ideal for road bikes and could lead to punctures. There's also a newly completed paved trail within Chatfield State Park that connects the C-470 Trail to the High Line Canal Trail, offering a smoother option in that area.

The sharp gravel on the Chatfield Dam is particularly challenging. It's generally more approachable for gravel bikes or mountain bikes, or road cyclists willing to navigate varied surfaces and potentially walk their bike in some areas.
