For this reason, as well as others, pets are prohibited in the backcountry and on trails and boardwalks. Pets are permitted within 25 feet of roads, parking lots, and campgrounds but must be kept crated, caged or restrained on a leash not to exceed six feet in length. Due to an increase in Parvo Virus deaths with wolf pups the park service is thinking of banning all pet dogs from the park. The virus is believed to have entered the park through visitors pet dogs and is a very deadly virus and difficult if not impossible to get rid of. Leave the dogs at home please.
Many animals have to be killed, or die each year due to unlawful feeding.
Feeding birds is just as bad as feeding a grizzly bear. Rafting, and canoeing are not allowed on any stream or river in Yellowstone. Boating or canoeing are allowed only on Yellowstone Lake, Lewis Lake, Shoshone Lake and the Lewis river channel between Lewis Lake and Shoshone Lake. A yearly fishing permit can be obtained at some entrances into Yellowstone, at any visitor service center, and most fishing shops, gas stations or stores outside Yellowstone Park. Most streams inside Yellowstone are fly fishing only, however there are certain areas on various streams or rivers that may open periodically to bait fishing.
