Niwot Trails

Trail Meter: 

The Niwot Trails are a system of trails which wind through and around the town of Niwot, a spaghetti bowl of trails which add up to about 6.4 miles total.  Spectacular mountain views and shady cottonwood-lined paths along irrigation canals await you.

A few small trailheads service the Niwot Trails network; parking is limited so please ride your bike to the trail if you're local.


  • Lefthand Valley Grange Trailhead off of N 83rd, just north of Niwot Rd
  • Niwot Trailhead off of N 79th, just north of Mineral Rd
  • Monarch Trailhead off of Monarch Rd, just west of N 79th


Beloved by locals for after-work strolls, these trails are popular in the evenings and on weekends for all types of users, so mountain bikers should be extra cautious with speeds and blind corners.  These trails vary in width and surface conditions.  Explore and learn!
