The Casque Isles Trail follows the Lake Superior shore between Terrace Bay, Schreiber, and Rossport, crossing beaches, bluffs, forest, and rough north-shore rock. The full trail is a multi-day hike, but Terrace Bay has access points for shorter walks, including the stretch between Aguasabon Falls and the beach.
Conditions are more serious than the map can make them look. Wear proper shoes, carry water, and ask locally about trail state if you plan anything beyond a short out-and-back.
