The National Park Service website notes that visitors should keep pets leashed at all times. Swimming in thermal pools and collecting natural features such as flowers, rocks or antlers is prohibited. Visitors should stay far enough away from all animals as to avoid disturbing them. Park rangers enforce these and other park rules, including bans on speeding and driving while intoxicated.
