PART 6: TOWER-ROOSEVELT TO COOKE CITY
This section, through the Lamar Valley, is a hotbed of wildlife activity. From bears and elk to bison and wolves, this is your best chance to make visual contact with the residents of Yellowstone. With Slough Creek and the Lamar River, there are some great chances to make contact with a few fish as well.
