Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult to follow accurately.

The South West Highlands is an extensive area of mountains, moorland, islands and sea which is home to several distinctly different cultures. The West Highland Way was Scotland's first long distance route and remains by far the most popular. It stretches for 94 miles from Milngavie on the edge of Glasgow to Fort William at the foot of Ben Nevis.

The South West Highlands area is very sparsely populated, with many mountain ranges including the highest mountain in the British Isles, Ben Nevis, standing at 1,344 metres. This mountain is a popular destination attracting an estimated 100,000 ascents a year. The 700 metre cliffs of the north face are among the highest in the UK, providing classic scrambles and rock climbs of all difficulties for climbers and mountaineers.
