It is worth mentioning that Two Elk at the top of Vail is at 11,200 Feet. There are people that will experience altitude "adjustment". In the summertime, it is highly advised to wear 100% UV sunglasses. At this altitude, eyes can become "sunburn" within a few hours. Likewise, suntan lotion is advised during the summer. Remember, about 82% of UV rays are filtered out from the atomosphere from 7,500 feet and below. The UV exposure can be high. We always wear shorts in the summer, but take a backpack with rain gear. If lighting and storms appear suddenly in the mountains, the gondola stops service. This can last minutes or for many hours.
Summer Activities: There is a great Frisbee Golf course! It is very different at high altitude in thin air.
