Where to Go for a Solo Jog or Walk

Hiker looking out Boulder, Co

Hey, if groups aren’t your thing, no sweat! These trails and paths are good for all levels and perfect for solo strolls or a workout with just you and your favorite running buddy.

  • Boulder Creek Path: Follow the Boulder Creek as it flows through downtown Boulder, stopping along the way to watch tubers and kayakers, or to grab a drink at a local coffee shop. Start on the paved path at Central Park (Broadway & Canyon Blvd.) and follow it east to Scott Carpenter Park (30th St. and Arapahoe) or farther, if you like.
  • Wonderland Lake: This 1.75-mile dirt trail starts on the south side of the Foothills Nature Center (4201 N. Broadway) and will take you around the lake. Keep your eyes on the sky for a glimpse of hang gliders and paragliders launching from nearby Wonderland Hill! 
  • Goose Creek Path: Start just south of the intersection at Valmont Rd. and Folsom St. and head east toward Foothills Parkway. You'll pass by Goose Creek Pond and end up near some of Boulder's favorite breweries (Boulder Beer Company, VisionQuest Brewery and Kettle and Spoke Brewery) as well as Redstone Meadery, if you fancy a post-workout adult beverage. 
  • Boulder Reservoir: You'll have to pay a small fee for access, but this 700-acre, multi-use recreation and water-storage facility is worth it. Walk or jog the 5.25-mile loop trail on graded dirt around the reservoir, best used Feb.–Nov. Watch for wildlife and people plying all sorts of watercraft. 
  • Teller Farm: Head to East Boulder and meander through historic and working farmland used for crop production, beekeeping and cattle and horse grazing, then enter the White Rocks Nature Preserve.
