The City of Boulder will implement closures along the Chautauqua Trail from Tuesday, Oct. 26, through Friday, Oct. 29, to conduct routine maintenance along one of Boulder’s most popular trails. Visitors will encounter closures between 8 a.m. and 5:30 p.m. while Boulder Open Space and Mountain Parks (OSMP) resurfaces the entire stretch of the .7-mile trail that leads to the Flatirons.   

Like many of the city’s trails along the mountain backdrop, the Chautauqua Trail is steep and is prone to erosion from rainfall, melting snow and sustained visitor traffic. While these “legacy” trails provide unique recreational experiences for the community, they require ongoing trail maintenance, which the city has identified as one of its top open space priorities.  

OSMP highly encourages community members to plan alternate destinations while this work occurs by visiting the city’s its interactive webmap and its new trail and trailhead web search feature. The new search feature provides open space trail closure information, along with details about:

  • Trail length 
  • Trail elevation gain 
  • Trail difficulty 
  • The type of activities allowed along the path 
  • Accessibility for community members experiencing disabilities
