The highest mountain in the British Isles, Ben Nevis (Beinn Nibheis) needs little introduction. The mist-shrouded peak attracts over a hundred thousand walkers every year, but that’s not to say it’s an easy way up—the 4,413-foot (1,345-metre) summit should only be tackled by those with hillwalking experience and navigation skills. Close to Fort William, the mountain is easy to access and there are two main routes to the top: the Mountain Track (also known as the Tourist Track or the Pony Track), which is the most trafficked, and the more challenging Carn Mor Dearg Arête.
June through October is the busiest season in Fort William and the surrounding Highland region, which can mean crowded trails and booked-up sites. If you want to avoid the crowds, spring is a good time to visit as the landscape will be lush and the temperature pleasantly cool enough for tackling the summit (but it will likely be freezing at the top). You can climb Ben Nevis year-round, but only very experienced climbers should attempt an ascent in the winter.
