At 978m (3209ft), England's highest mountain features on every self-respecting hiker's bucket list. The classic route starts from Wasdale Head; it's hard going but within the reach of most moderately fit walkers, although it's steep and hard to navigate in bad weather. It's a return trip of around six to seven hours. Proper gear is essential: raincoat, rucksack (backpack), map, food, water and hiking boots. A favorable weather forecast is preferable to make the most of the views.
Along with Scafell Pike, Helvellyn is the challenging hike everyone wants to do. The classic ascent in The Lake District takes in the twin ridges of Striding and Swirral Edge, which are spectacular but very exposed and involve some scrambling and dizzyingly steep drops on either side – if you're at all nervous of heights, Helvellyn is not the fell for you. The usual routes climb up through Glenridding or Patterdale. Always check the weather forecast and take all the necessary supplies.
