Vigorous Trek

Anything from 14 to 30 days’ trekking, and aimed at the fit, experienced enthusiast. Sometimes more than 7 days consecutive walking but with rest days interspersed, and at least one challenging high pass crossing over 5000m. Generally more demanding than the previous grade, together with the possibility of scrambling and glacier travel, and sometimes of optional trekking peaks, thereby justifying the Vigorous grade. Some camping above the snowline; crampons, safety ropes and ice axes may be needed, so experience of these is essential.
