1. Great Himalaya Trail, Nepal

This recently inaugurated trail is made up of a network of existing paths traversing Nepal. It will eventually form part of a 4, 500-kilometre (2, 800-mile) “super trail” linking Bhutan and Pakistan. The existing 1, 700km Nepal section divides into smaller routes passing in sight of eight of the world’s 8, 000-metre (26, 247ft-plus) peaks and through some of the world’s most remote villages. The trail crosses mountain passes up to 6, 000 metres in altitude while climbing a total of 150, 000 metres.

The full escorted 157-day trek with World Expeditions costs £20, 490, but the seven shorter connecting stages range from the 18-day Langtang Trek (£2, 350) to the 34-day Makalu & Everest Traverse led by the climbing legend Stephen Venables (£3, 850). Prices include airport transfers, expert mountain guides, porters, trekking permits, equipment and all meals, but not flights.
