Layered clothing, gloves, and thermal hat.
GPS or map track, compass, and detailed map.
First aid kit and emergency bivouac material.
Energy food and water reserve.

Two technical passages to consider: small wall below Rocca di Santa Caterina (IV-, equipped) and descent from Punta Taviela (to be assessed based on conditions).
Numerous sections on crevassed glacier: rope, harness, and technical equipment essential.
Possibility of sudden bad weather and rapid changes in conditions: always check the weather and snow report.
Several exit options along the route, but all require orientation and knowledge of the slopes.

T6

Recommended period: from late June to September, depending on snow and glacier conditions.
It is optimal to undertake the traverse with alpine guides, especially for less experienced groups.
Overnight stay recommended at huts or bivouacs to better manage time and strength.
Always check the opening status of huts and availability of beds.
The itinerary passes through fragile and delicate high-altitude areas: respect for the environment and minimizing impact are essential.
