Weather Recreationists are urged to pay attention to the weather when travelling in the mountains. In the summer, afternoon thunder storms are common. Ridgelines should be avoided during storms due to the possibility of lightning. Snow is possible at any time of year. It is advisable to check weather conditions before recreating or traveling during the winter.
Brochures are available describing each of the wilderness areas.
Campsites must be located greater than 200 feet from trails and water sources. Group size is limited to 15 people. Permits are required in the Bridger Wilderness for organized groups, and overnight stock use, otherwise permits are not required when backpacking on the Bridger-Teton. Backpackers in Grand Teton and Yellowstone National Parks must obtain backcountry camping permits from visitor centers and ranger stations in the appropriate park. Look for bald eagles along rivers and near lakes throughout the Forest.
