The purpose for the issuance of this Commercial Use Authorization (CUA, previously titled Incidental Business Permit) is to regulate and oversee operations of permit holders involved in conducting commercial guided day hiking and overnight backpacking activities in Yosemite National Park. In addition to this base permit, additional permitted activity conditions may be attached depending on the holder's request. (When multiple activity permits are requested the additional conditions are attached to the hiking/backpacking permit rather than issuing each permit separately.) These additional activities include Nordic Guiding involving cross-country skiing and snowshoeing, guided fishing, and photography workshops. Conditions for these additional activities are stipulated in the body of the individual permit for each activity. These permits are being submitted separately. The permitted activities are to be conducted only in those areas of Yosemite National Park open to the public and authorized by the permit. The permit holder is required to obtain any additional permits or license required by law.
