The 1883 Pony Track to the summit (also known as the Ben Path, the Mountain Path or the Tourist Route) remains the simplest and most popular route of ascent. It begins at Achintee on the east side of Glen Nevis about from Fort William town centre, at around 20 metres above sea level. Bridges from the Visitor Centre and the youth hostel now allow access from the west side of Glen Nevis. The path climbs steeply to the saddle by Lochan Meall an t-Suidhe (colloquially known as the 'Halfway Lake') at 570 m, then ascends the remaining 700 metres up the stony west flank of Ben Nevis in a series of zig-zags. The path is regularly maintained but running water, uneven rocks and loose scree make it hazardous and slippery in places. Thanks to the zig-zags, the path is not unusually steep apart from in the initial stages, but inexperienced walkers should be aware that the descent is relatively arduous and wearing on the knees.
