Summer Safety


Fire Danger

Smoking is prohibited on lifts and is only allowed in designated smoking areas. Report fires immediately via cell or on-mountain emergency phones.

Sun Protection

The Sun’s rays are much more intense at altitude. We recommend sunscreen with a sun protection factor of 15 or higher as well as eye protection.

Lightning and Thunderstorms

Afternoon thunderstorms are common in the mountains. Take proper precautions when you see or hear a storm developing: Seek shelter, keep off ridgelines, and stay clear of chairlift houses, lift towers, power lines, open spaces, lone trees and signposts. Lifts may close on occasion, causing delays.

High-Altitude Environment

If you live at a lower elevation, you may tire more easily. Take it easy at first, plan short trips until you are acclimated and drink plenty of water. Some visitors may experience symptoms associated with Kirkwood’s high altitude. Symptoms may include headaches, nausea, and dizziness, loss of appetite, restless sleep, coughing and difficulty in breathing. If symptoms persist or if you have a concern about your health, you should seek medical attention.

Adequate Clothing

Be aware, mountain weather changes quickly and there is usually at least a 10 degree temperature difference from the bottom to the top of the lifts. Bring a raincoat and consider a sweater or fleece.

Lift Safety

Under the law, you cannot board a lift unless you have sufficient physical dexterity, ability and knowledge to negotiate or to use such lift safely or until you have asked for and received information sufficient to enable you to use the lift safely. You may not use a lift when under the influence of drugs or alcohol. Please lower the bar when riding lifts.

Weather and Terrain

YOU ASSUME THE RISK of unpredictable weather, as well as rugged, uneven, irregular and slippery conditions.


Be aware that trails and roads on Kirkwood Mountain Resort are used for many purposes during the summer. Mountain bikes, hikers, horses, motorized vehicles, construction equipment and others may be encountered at any time.

Construction Warning

You may encounter construction equipment, maintenance vehicles or other heavy machinery at any time. Always be cautious and obey posted signs and warnings.

Mountain Biking

Helmets and sturdy shoes with good tread are recommended at all times. Child carriers or tow-behind bikes are not permitted and all bikes must have two working brakes. All loose clothing, bags or packs should be firmly secured so they do not interfere with the bicycle’s moving parts.

Mountain bikers must always yield to other non-motorized trail users. Should you encounter hikers or horses on any trail, you must yield the right-of-way. Ride on designated trails only and obey all posted signs and warnings. Failure to do so may result in lift ticket and/or pass revocation.


Do not litter or feed wildlife. Hikers rarely encounter bears but, if you do, please remain calm and back away slowly. Kirkwood asks that everyone is cautious and respectful of wildlife
