You should plan to arrive in Cody, Wyoming, on Friday or Saturday. Friday is recommended, since a Friday arrival will give you time to become accustomed to the altitude and the climate. Also, this may provide you with an opportunity to do some last minute shopping or just to visit Cody.
If you plan to fly fish, then you may want to take time to visit the local fly shops and to purchase a fishing license for Yellowstone Park ($ 10). You will also have an opportunity to purchase a fishing license for the Park at the gate if time in Cody does not permit you to accomplish this. Two days have been set aside for fly-fishing in the Backcountry of Yellowstone Park. Additionally, if you like, you can take advantage of fly-fishing in the evenings at all the campsites except for the camp at Mist Creek and the camp at Hoodoo Basin. It is suggested that you call the fly shops in Cody to inquire if they sell fishing licenses for Yellowstone Park, since not all do.
Cody is a wonderful small western town to visit with a number of points of interest and places to visit. For example, you could visit Trail Town. This collection consists of 26 buildings, which date from 1879 to 1902, one hundred horse-drawn vehicles, plus an extensive collection of Native American artifacts and western memorabilia of the Wyoming Frontier. The Buffalo Bill Historical Center is the home of the Buffalo Bill Museum, Whitney Gallery of Western Art, Plains Indian Museum, and the Cody Firearms Museum. Together, the museums provide you with a rare opportunity to explore Western history and art. Shopping in downtown Cody along Main Street is always a treat to the visitor as is attending the nightly Cody Rodeo during the summer.
