More ways to explore the area's outdoor wonders
You begin on a wind-scoured pebble beach, the Strait of Magellan bristling with cold light, then step into a rainforest that feels intent on slowing you down. Trees lean into the wind; moss and dripping ferns close over a narrow tread that soon pitches upward. The trail trades salt air for timber scent as the forest gives way to open alpine scrub and a final, rocky spine to Mount Tarn’s summit.

Conservation
This coastal-Andean environment has fragile peatlands and slow-growing vegetation — stick to trails, pack out waste, and support local guides and family-run estancias.

Start early for calmer winds
Morning hours typically bring lighter winds and more stable weather near the summit; aim to be hiking before 08:00.
Bring waterproof, breathable layers
The route moves through wet forest and exposed ridgelines — a waterproof shell and breathable base layers keep you comfortable.
Mind fragile peat and tundra
Stay on the trail to avoid compressing peat soils that take decades to recover and protect native vegetation.
Fuel and hydrate proactively
Carry high-calorie snacks and at least 2–3 liters of water; cold weather disguises dehydration.
Waterproof hardshell jacket
Protects against sudden wind and rain common on the coastal Andes ridgeline.
Sturdy waterproof hiking boots (ankle support)
Required for muddy forest sections and rocky, uneven summit terrain.
Trekking poles
Helps with balance on steep descents and reduces strain on knees.
Warm insulating layer (fleece or down)
Summit exposure and coastal wind can make temperatures drop sharply even in summer.
