Protecting The Resources We Love

Open Space and Mountain Parks is a popular destination for climbers and boulderers alike.

The diversity of outcroppings and boulder fields provide climbers of any skill level a challenge.

Help preserve this experience for all visitors by respecting seasonal raptor and bat closures, and using designated trails when accessing your climb. Social trails can lead to fragmentation of wildlife corridors and indirectly affect wildlife behavior.

Check for Closures

Please check for any trail and area closures before your visit! Permanent and seasonal bat roosting site closures and seasonal cliff-nesting raptor closures may affect climbing areas. View OSMP's interactive wildlife closure map to help plan your visit.

Off-trail permits are required to access some climbing areas in Habitat Conservation Areas (HCAs). All designated OSMP trails near raptor wildlife closures remain open.

OSMP requests that climbing gear not be left unattended. Unattended gear and ropes may hinder other’s ability to climb or enjoy the natural scenery.

Bolted Routes

Apply for a New Route

Open Space and Mountain Parks provides hundreds of bolted and traditional climbing routes to climb and enjoy. To apply for a new route send an email to and a copy to with a description of the route that includes: brief route description with number of new bolts, area, cliff or rock face, first name, last name, phone number(s), and email address. Applicants will be required to fill out an Application for New Bolted Route. The Fixed Hardware Review Committee (FHRC) makes application recommendations to OSMP. For more about the FHRC process, please visit the Flatirons Climbing Council Fixed Hardware Program. OSMP makes the decision on all applications.

It is illegal to place fixed protection without a permit.

Replace an Unsafe Bolt

If you should come across what you determine to be an unsafe bolt and wish to replace it, please use the Application for Bolt Replacement Form. Should your request be approved, we thank you for wishing to make climbing safer for everyone!
