To complete the National Three Peaks Challenge you have to climb the highest peaks of each of the island\'s three countries (Snowdon, Ben Nevis and Scafell Pike), usually in less than 24 hours. The National Three Peaks map set covers the top summits in stunning colour detail, with every track and path clearly marked to help you complete your challenge. You save 20% by buying them as a set. With all OL maps in this set you will receive a code for use on your iOS or Android smartphone or tablet. The maps included are: Sheet 392 Ben Nevis and Fort William, OL6 The English Lakes: South Western Area and OL17 Snowdon. The mountains climbed, in order of elevation, are Ben Nevis in western Scotland, 1,344 metres (4,409 ft), Snowdon in North Wales, 1,085 metres (3,560 ft), and Scafell Pike in The Lake District, 978 metres (3,209 ft). The peaks are usually climbed in the order: Ben Nevis in the evening, Scafell Pike in the early morning and Snowdon in the mid- to late-afternoon. Ben Nevis is the highest and the hardest of the national three peaks, a gruelling uphill struggle and very tough on the knees going back down. The main path up \'The Ben\' is obvious can be done in fading light as long as you find the right path down. Scafell Pike has many start points and paths to the top, but they are less clear. There are also numerous routes up Snowdon, from the easier and popular routes like the Pyg Track to the potentially scary Crib Goch ridge. Average time for Snowdon is 4 hours, with 5 hours each for both Ben Nevis and Scafell Pike, (14 hours total) plus a maximum of 10 hours travel time between the start and end points of the 3 peaks. Doing the challenge in a group for charity is now the most popular way and has the added benefit of wide-awake drivers. After scaling the three highest peaks you\'ll almost certainly want to go back and try one or more of them again.
