For these tours, you have to be an intermediate canyoneer in excellent physical condition. Prior experience is preferred but not required for tours in Oak Creek and Upper Uncompahgre. If you don’t have canyoning experience but you live a highly active lifestyle, climb regularly (lead, top rope), are an avid whitewater paddler, have experience working with ropes or at height, then you might be suited to intermediate canyons. Keep in mind that you will also have to hike up to 60 minutes with gear in tow on uneven terrain. Swimming experience is also necessary because of waterfalls and plunge pools.
For Oak Creek (3C2 / V3.A4.III) and Upper Uncompahgre (3CIII / V3.A4.III), you will have to rappel for 30 m/100 ft and use a rope and safety lines. Be ready for prolonged immersion in cold water and moderate current. You might have to perform simple jumps between 5 m/ 16 ft and 8 m/ 26 ft.
For canyoning in Bear Creek (3C3 / V4.A4.IV), you should be prepared for low to moderate vertical flows, rappels over 30 m/100 ft, rough rock edges requiring rope management and landing pools that have current. Setting safety lines will be more difficult.
