At the hands-on Swiss National Park Centre, an audioguide gives you the low-down on conservation, wildlife and environmental change. Staff can provide details on hikes in the park, including the three-hour hike from S-chanf to Alp Trupchun (particularly popular in autumn, when you might spy rutting deer), and the less strenuous, family-friendly Naturlehrpfad circuit near Il Fuorn, where bearded vultures can often be sighted.
