An easily accessed Munro, Beinn Challum may look uninspiring from the Crianlarich side, but this is deceptive. There’s some impressive terrain hidden away on the north flank, while even the summit ridge has more character than you might think. It’s a big hill, but not a big day, which makes this a good winter target when light is limited. With an exciting flavour of mountaineering (but just a hint – no ropes required) the northwest spur has to be the most interesting winter way up the hill, but with its comparative remoteness it’s a route few people seem to know about. It'd be good in summer too of course. Go up this way, then descend by the more frequently trodden Munro bagger’s path to complete a full traverse of a surprisingly worthwhile mountain.
