From the Boulder Creek Path running car-free through the heart of town to the LoBo / US-36 bikeway out to Longmont, Boulder is one of the most rideable cities in the country. Plan a low-stress route or a distance loop, and find the coffee, beer, and bike shops along the way.
Boulder packs a remarkable amount of car-free riding into a small city — the Boulder Creek Path is the spine, and a web of underpasses lets you cross town without stopping at a single light. Here are the routes worth knowing.
The spine — flat and car-free from the mouth of Boulder Canyon east through downtown and the CU campus out to Valmont, with underpasses at nearly every cross street.
The Longmont-to-Boulder path — a scenic, mostly separated route along the diagonal highway linking the two towns past open space and farmland.
An east–west greenway threading north Boulder neighborhoods, tying into the Boulder Creek Path and the Foothills Trail — quiet and almost entirely off-street.
South of town through wetlands and cottonwoods — a calm, flat ride past prairie-dog colonies toward Marshall and the South Boulder Rec Center.
A separated path up the canyon mouth toward Four Mile — the gentle on-ramp to Boulder's legendary canyon climbs without riding the shoulder of CO-119.
North Boulder's connector network — links Wonderland Lake and the north neighborhoods into the creek path and the start of the LoBo.
Coffee, beer, food, and bike shops along Boulder's trails and protected lanes.

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.
