Lonely Planet review
Along with Scafell Pike, this challenging hike is the one everyone wants to do. The classic ascent 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 in probably not the fell for you.
The usual routes climb up through Glenridding or Patterdale. As usual, check the weather forecast and take all the necessary supplies.
