At Jenny Lake is located the park museum, which also serves as the ranger station. In it are housed exhibits pertaining to the history, geology, fauna, and flora of the Teton-Jackson Hole country. The collection devoted to mountaineering is in many respects unique. Adjacent to the museum is an open-air amphitheater where campfire talks on geology, wildlife, and other subjects related to the park are given every evening at dusk by a ranger-naturalist. A nature walk, auto caravan, or all-day hike is conducted each day by a member of the ranger-naturalist staff.

An information desk is maintained at the museum, and rangers are there at all hours of the day to answer inquiries. Information service is also maintained at park headquarters.
