The Coal Creek Trail runs car-free clear across town and links Louisville to Superior, Lafayette, and the LoBo bikeway toward Boulder. Davidson Mesa serves up the classic Flatirons view, and award-winning historic Main Street is the perfect finish. Plan a low-stress route or a distance loop.
Louisville's riding centers on the Coal Creek Trail — a flat, car-free corridor that ties the town to its neighbors and the wider Boulder County path network — plus open-space mesas with front-range views and one of the best small downtowns in Colorado. Here's the backbone.
The spine — a flat, car-free path along Coal Creek across town, connecting west to Superior and east to Lafayette and the regional network.
Link from the Coal Creek corridor onto the US-36 / LoBo bikeway for a mostly separated ride into Boulder.
The iconic Flatirons-view overlook above town — open-space paths and the postcard panorama that defines the area.
A calm lake loop and neighborhood connector tying into the Coal Creek Trail — easy, scenic, family-friendly.

Tie south and west toward Marshall Mesa's open-space trails for a dirt loop with big views.
Breweries, bakeries, and food along Coal Creek and historic Main Street.

Every street and path is graded for how calm and connected it really is — so the route you get is one you'll actually enjoy.
Trails, lanes, and quiet streets are color-graded by stress level — cool means calm, red means watch out.
Want a 12-mile ride? Get loops that hit your target and bring you back home, not an out-and-back you have to reverse.
The map flags uncontrolled crossings — busy roads with no signal — so nothing catches you off guard.
See the climb before you commit, and flip on “prefer flat” when you (or the kids) aren't in the mood for hills.
Search an address, drop a pin, or use your location. Or pick “Loop ride” and just set a distance.
Kid-friendly, relaxed, or anything-goes. Trazo biases the route toward protected paths to match — and you can drag the line to add a stop.
