Individual Rock Climbing Permits (free):
Individual permits are available year-round at the park office. Weekends in May and daily Memorial Day through mid-October, permits are also available at the visitor center. Individual climbing permits are also available at the self pay kiosk near the visitor center.

Commercial Rock Climbing Permits (free):
Organized groups are required to obtain a new commercial climbing permit each year. This requires submitting a certificate of insurance with required liability limits and naming the State Of Minnesota as an additional insured party. Application forms are available by calling the park office at 651-539-4500. Requests for new commercial climbing permits should be submitted at least seven days prior to the climbing event to allow time to process the permit request.

Minnesota State Parks strongly endorse a "clean climbing" philosophy. In all but very limited, pre-approved instances, placement of hardware will be limited to that which can be temporarily placed using the climber's fingers. All such protection must be placed and removed without altering the rock."
