Lethendry Castle

A crumbling 17th-century fortress sitting quietly on its own patch of Highland moorland, Lethendry Castle is the sort of place you'll stumble upon rather than plan around. The ruins aren't much to look at from a distance - just grey stone walls emerging from rough grass - but get closer and there's something compelling about the decay. You can make out the tower house structure, see where the main building once stood, and imagine the small garrison that held this remote corner of Strathspey.

It's not a destination that demands hours. Twenty minutes is enough to walk around the perimeter, peer at what's left of the stonework, and take a few photographs if the light's decent. The real appeal here is the quiet. No interpretation boards, no crowds, no entrance fee that you'll regret paying. History enthusiasts and photographers will appreciate it more than families with young kids, who'll likely grow restless once they've climbed on the accessible bits.

Grantown-on-Spey, the nearest proper town, sits about three miles away - handy for a coffee stop or supplies. If you're based at Grantown on Spey Caravan Park, this makes an easy afternoon detour during your park holiday in the area. The access can be muddy depending on the season, so decent boots are worth bringing. Best in late spring or early autumn when the light's warmer and the midges less ferocious.
