Essential things to carry Keystone
While visiting Keystone make sure that you carry a locator map to help you find each place and get information about the eateries and accommodations available in the city.
This can also be obtained at the Keystone Chamber of Commerce. If you plan to go hiking near the Mount Rushmore area then be sure to carry a nice pair of sneakers or walking shoes. A light backpack would be handy as well.
Cameras and Camcorders are allowed so do not forget to pack them. The weather is pleasant and there is very little rain especially in summer.
However, the temperatures tend to fluctuate so do carry dresses in layers and avoid dressy clothes as the city has a rugged outdoor atmosphere which requires rough and tough apparels such as jeans and t-shirts.
