Weather in the mountains can change in the blink of an eye, so it is a good idea to dress in layers (i.e. tank top or t-shirt, long sleeved shirt and a sweatshirt or light jacket). Closed-toe shoes and pants are required. Your own hat (or one of our helmets), sunscreen and a water bottle are also recommended. You are always encouraged to have a light rain jacket, but please no loose ponchos.
