The Signal Mountain Summit Road and surrounding area in Grand Teton National Park have again been temporarily closed to all visitors including motorists, cyclists, and hikers, due to heightened bear activity.Park rangers will monitor the situation and will reopen the road when conditions allow. However, the road could be temporarily closed through the weekend or longer. Rangers remind visitors to “Be Bear Aware,” as these animals are active throughout park. They are protective of their feeding areas and their young. All visitors are required to maintain a distance of at least 100 yards from bears and always carry bear spray, as well as make noise and travel in groups when they are hiking. Some of the most popular areas and trails pass through prime bear habitat.
