Tom nan Oisgin (Oisgean)

Tom nan Oisgin sits on the eastern shore of Loch Lomond, a modest hill that punches above its weight for views. The walk up takes about ninety minutes from the road - it's steep in patches but nothing technical, and you'll find yourself among proper hillwalking terrain with Loch Lomond spread out below.

What makes it worth the effort is the perspective. You're looking down the length of the loch towards Glasgow, with the Trossachs rising up across the water. On a clear day it's genuinely striking. The summit itself is bare enough that you get 360-degree views without trees blocking the sightlines. On wet days the path turns into a bog, so check the weather first.

This is best suited to walkers who don't mind getting muddy and aren't looking for a quick stroll. Families with older kids might manage it, but younger ones will find it a slog. Allow three hours there and back if you're taking your time. It's free, naturally - just park sensibly at the base and respect the land.

If you're staying at one of the glamping sites nearby - Milarrochy Bay is closest at just over a mile away - it makes a proper day out. Combine it with a walk along the loch shore or an afternoon on the water. The peak works best as part of a longer Loch Lomond trip rather than a standalone visit, but for hillwalkers who know what they're in for, it's the real deal.
