Entry No. 96 — the Denver file — filed under: nature
Sand Creek Regional Greenway Trail
A near-13-mile creek-and-cottonwood corridor that threads straight through Denver's industrial north — past rail yards, refineries, and the backs of warehouses — yet quietly harbors hawks, deer, beaver, and prairie dogs the whole way. Most Denverites never set foot up here because there's no reason to drive into Globeville or Commerce City; that's exactly why it stays empty. String together Bluff Lake Nature Center, the Urban Farm, and Star K Ranch and you've got hours of wild creekside with the skyline at your back. Open sunup to sundown, multiple trailheads, paved on the Denver/Commerce City stretches.
The story
If you ask the average Denverite for trail recommendations, they’ll send you west toward the foothills or onto the manicured loops of Washington Park. Nobody tells you to head into the industrial north, which is precisely why the Sand Creek Regional Greenway stays empty. Spanning nearly 13 miles from Aurora’s Triple Creek Trailhead to the South Platte River confluence in Commerce City, this path cuts straight through a side of the metro area most people actively ignore: rail yards, metal warehouses, and the sprawling tanks of an oil refinery.
The creek snaking alongside the trail bears the heavy marks of industrial history, passing through zones long dominated by chemical plants and manufacturing. Yet instead of choking into a dead ditch, the riparian cottonwood corridor held on. What exists now is a post-industrial wilderness where wildlife has simply adapted to heavy infrastructure. You can ride past petroleum storage facilities in Commerce City and spot red-tailed hawks on chain-link fences, or watch beavers building lodges in water quiet enough to reflect industrial pipe bridges.
Because there is little reason for suburban commuters or tourists to turn off toward the warehouse districts of Globeville or Commerce City, the greenway remains quietly forgotten. Connecting sanctuaries like Bluff Lake Nature Center, The Urban Farm, and Morrison Nature Center at Star K Ranch, the trail gives you hours of uncrowded creekside path with the Denver skyline sitting framed behind smoke plumes and cottonwood branches at your back.
What it's like
Expect a trail of stark contrasts where smooth pavement in Denver and Commerce City gives way to crushed gravel and dirt as you push south into Aurora. The industrial stretch near the refinery can occasionally carry a faint smell of petroleum, but the trade-off is solitude. Access the greenway via the Bluff Lake trailhead off Havana Way for easy parking and restrooms, keeping in mind that while the main greenway allows bikes and leashed dogs, the fenced Bluff Lake preserve inside permits neither and locks its gates at dusk. Time your visit for early morning or golden hour when cottonwoods shade the path and Great Blue Herons, mule deer, and beavers come out along the water.
The move: Bike or walk a quiet stretch from the Bluff Lake trailhead at golden hour, watch for herons and beaver along the creek, and end with tacos somewhere in Commerce City on the way out.
📍 Before you go Two nature centers make the cleanest entry points — Bluff Lake (off Havana Way near Central Park/Stapleton) for the Denver end, and Morrison Nature Center at Star K Ranch (off Smith Road in Aurora) for the south — both with parking, restrooms, and short connector paths down to the greenway. The trail itself welcomes leashed dogs and bikes, but the Bluff Lake preserve inside its fence allows neither, and its gates lock at dusk. Cottonwoods give shade, so summer mornings and golden hour are best — that's also when hawks, deer, and beaver are most active. Pair it with the on-site Urban Farm.
