For very experienced hikers with a high level of fitness. Navigation skills required. Strenuous itineraries include steep ascents and descents over rough and varied terrain in higher mountain regions and may include some exposed areas, fixed ropes and scrambling. These trips may be in expedition-style and may require hard trekking every day. The itinerary may include hut to hut walks on some or all days and require carrying your own belongings/backpack along the route. Strenuous grade walking holidays include on average 8-10 hours of walking per day (30+ km of walking).
