Footwear matters
Choose sturdy hiking boots with good grip; the trail has rocky and loose scree sections that become slick when wet.
Bring layers
Summit exposure brings wind even on warm days—carry a light wind shell and an insulating mid-layer.
Hydration and snacks
Carry at least 1–2 liters of water and energy snacks; bottled water is provided but bring your preferred electrolytes.
Timing your day
Start mid-morning if you prefer quieter trails; the guide times lunch at a mountain hut on the descent.
Hiking boots
Provide traction and ankle support on rocky trails and loose scree.
Light rain shell
Wind and sudden showers are common on exposed ridgelines; a waterproof layer keeps you comfortable.
Trekking poles
Help on steep ascents and loose descents, reducing knee strain.
Daypack with 1–2L water
Carries layers, water, snacks and camera for a full-day outing.
