Sunburns and adventure sport-related injuries are the two biggest issues you may face while vacationing in Keystone. Even if the sky is overcast, do not forget to put on your sunscreen, especially when you have a full day of skiing planned. The white snow is an excellent reflector of sunlight, and if you are not properly protected, you may end the day with a severe sunburn. Bring along a small container of sunscreen with you during the day so that you can reapply every so often. You'll be happy you did when the day is over and you do not have the telltale raccoon-eye sunglasses tan that others might be sporting. In addition, bring along some water if you can -- it is very easy to dehydrate during a long day of sporting activity. If you start to get lightheaded or feel a headache is on the way, slow down, take a break, and hydrate.

Whether 'cool' or not, be sure to wear whatever safety gear is required by your sport. Mountain cyclists should wear helmets; snowboarders should consider doing the same during the winter. If you are new to wintersports, definitely plan to take a lesson. Learning a few basics can definitely help you avoid injuries on the slopes.

If you are skiing or riding learn the code Always stay in control, and be able to stop or avoid other people or objects. People ahead of you have the right of way. It is your responsibility to avoid them. You must not stop where you obstruct a trail, or are not visible from above. Whenever starting downhill or merging into a trail, look uphill and yield to others. Always use devices to help prevent runaway equipment. Observe all posted signs and warnings. Keep off closed trails and out of closed areas. Prior to using any lift, you must have the knowledge and ability to load, ride and unload safely. At each and every ski resort, this Skier Responsibility Code is taken very seriously. Any failure to ski responsibly, and to use good judgment and common sense, can result in the revocation of skiing privileges. There typically isn't much tolerance for those who disobey the rules. Be aware, that in many cases, state law becomes involved in flagrant violation of boundary restrictions and unreported collisions. Many resorts are now turning reckless skiers over to law authorities. Follow the code or risk going to the pokey for a day or longer.
