Longmont is laced with car-free greenways — the St. Vrain runs the width of town, and a quiet grid of creek and ditch paths connects almost everywhere without a busy road. Add the LoBo bikeway to Boulder and it's one of the most underrated places to ride on the Front Range. Plan a low-stress route or a distance loop.
Longmont quietly built one of the best municipal greenway networks in Colorado — creek paths and ditch trails that let you cross town, reach the parks, and link out to Boulder almost entirely off-street. Here's the backbone.
The spine — a flat, car-free path tracing the St. Vrain Creek the full width of town, stringing together Golden Ponds, Roosevelt Park, and Sandstone Ranch on the east end.
The Longmont-to-Boulder path — a scenic, mostly separated route southwest along the diagonal past open space and farmland, the easy way to ride between the two towns.
A calm creek-side connector through the south and west neighborhoods, tying into the St. Vrain and the city's quieter residential grid.
A north-side ditch-and-creek path linking parks and schools — almost entirely off-street, a favorite for easy family rides.
The ditch-trail web that makes Longmont so rideable — flat, shaded service paths that quietly connect the east and north sides without a single busy crossing.
The east-side payoff — the greenway runs out to Sandstone Ranch's open space, with a spur toward Union Reservoir for a longer flat loop on the prairie.
Breweries, coffee, and food along Longmont's greenways 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.
