Ptarmigan

The walk up Ptarmigan starts from the Loch Lomond side near Alexandria, and it's a proper slog but the views make it worthwhile. You're climbing 747 metres to bag this Munro, which takes most people three to four hours return depending on fitness. The path itself isn't overly technical - it's more about stamina than scrambling - though the weather can turn quickly up here, so don't underestimate it.

What makes Ptarmigan worth the effort is the panorama from the top. You get Loch Lomond stretching out below, Ben Lomond shouldering in from the south, and on clear days the view pushes right across the Highlands. The name itself comes from the mountain hare, though spotting one is less certain than bumping into other hikers at the summit.

This is strictly for walkers with decent legs and hill sense. Families might find it tough unless the kids are experienced; under two hours up is manageable for most competent hikers, but you need to respect the exposure and weather exposure at altitude. There's no facilities at the peak, so bring water and layers even if it's sunny at the base.

If you're staying at Inverbeg Holiday Park or Loch Lomond Holiday Park, Ptarmigan works as a proper full-day mission rather than a casual stroll. Forest Holidays Ardgartan is slightly further out but puts you in decent walking territory. Go midweek if you can - weekends bring the crowds.
