This guide focuses on touring—road, gravel, and e-bike-friendly routes—that let you sample scenery, local flavor, and easy access to both singletrack sidetrips and longer point-to-point rides.

The city from the water

Why Longmont Works for Bike Tours

Longmont occupies a clear, usable edge between two cycling worlds: the calm, cultivated network of greenways, paved paths, and low-traffic county lanes that are perfect for relaxed day touring, and the rawer foothills corridors that give riders a taste of Colorado’s mountain light and long-distance potential. On any given morning you can roll out from a downtown coffee shop onto a smooth riverside bike path and, within an hour, be pedaling quiet farm roads with golden fields on one side and the dark silhouette of the Front Range on the other. That duality—accessible urban amenities plus immediate access to rural and mountain landscapes—makes Longmont a practical base for travelers who want variety within short distances. The St. Vrain Greenway threads through the city and acts like a spine: it's flat, scenic, and bike-friendly, ideal for warming up or showing less experienced riders how comfortable Colorado riding can be. From the greenway, a web of county roads and designated bike routes fans out toward historic towns, agricultural parcels, and foothills gateways. These roads are where a bike tour becomes more than exercise; it becomes a travel day. You encounter local life—farmstands, breweries that welcome riders, and small-town main streets—without committing to long, technical climbs. For riders seeking more terrain, the nearby canyon approaches (Left Hand and others toward Boulder and Lyons) provide direct, short climbs into the foothills with big views and the chance to tack on singletrack or gravel segments. Longmont also lends itself to multi-ride itineraries. Mornings can be dedicated to exploring paved river corridors and neighborhood greenways; afternoons can be spent on gravel backroads or sampling local craft food and drink. E-bikes have broadened what’s possible here: less fit riders can still enjoy long-distance scenic loops and rolling country routes, while experienced cyclists can push into more demanding foothill options. Seasonality matters—spring brings wildflowers and cool mornings, summer opens long-day options but warns of afternoon thunderstorms in the foothills, and fall condenses the touring window into crisp, sun-drenched days with excellent visibility. Winter touring is possible but requires attention to wind, snow on exposed sections, and limited daylight. In short, Longmont’s charm for bike touring lies in variety and proximity: you can stitch together short, safe, scenic rides or configure multi-stop touring days that feel exploratory without requiring full wilderness experience.

Accessibility is a practical advantage: Longmont is a short drive from Boulder and Denver, and regional roads provide easy, direct access to both mountain approaches and prairie-style touring. That proximity makes it an efficient overnight base for riders who want a taste of the Front Range without committing to long transfers.

Complementary experiences—farm-to-table restaurants, bike-friendly breweries, and a local outdoor culture—mean that touring here feels like travel rather than a workout. Routes are often punctuated by worthwhile stops, so rides can be planned around coffee, lunch, and gear-resupply points.

Seasonal planning

Best Time to Visit

Longmont is warm year-round, but wind, swell, migration, visibility, and demand change the best match between traveler and trip.

Year-round destination

Seasonal highlights change the reason to go

Winter favors humpback encounters; warmer, calmer months favor snorkeling visibility and smoother water.

Humpback season

Late spring through early fall, with weekends busiest for popular greenway sections and brewery stops.

Prime whale watching, winter holidays, higher demand, and earlier sell-outs.

Snorkeling window

May–June–September–October

Typically gentler seas and clearer water for snorkeling trips.

Weather notes

Trade winds year-round

Spring and early summer offer cool mornings and long days; late summer can be hot on exposed prairie roads with afternoon thunderstorms developing in the foothills. Fall delivers stable, crisp conditions and excellent visibility. Winter can be cold and occasionally snowy—pack for wind and shorter daylight if touring then.

Quieter opportunities

Late spring & summer weekdays

Late fall weekdays and winter rides provide solitude and a different light; choose lower-elevation, paved routes and be prepared for wind and colder temperatures.
