The most southerly point on the continent, Cabo Froward (Cape Froward) is 90km south of Punta Arenas and accessible by a two-day hike along wind-whipped cliffs. At the cape, a 365m hill leads to an enormous cross, originally erected by Señor Fagnano in 1913; the latest one was erected in 1987 for Pope John Paul II's visit. Camping is possible along the trail. Ask about guided hikes at any of the tour companies in Punta Arenas or Puerto Natales–based Erratic Rock.
Faro San Isidro, about 15km before Cabo Froward, is a lighthouse near the base of Monte Tarn (830m). This rugged area is home to prolific birdlife and some good hiking. It's also a launch point for humpback whale–watching trips to Isla Carlos III in Parque Marino Francisco Coloane, Chile's first marine park. Humpbacks and minke whales feed seasonally here between December and May.
