Piteadie Castle

The ruins of Piteadie Castle sit on a low rise just outside Burntisland, and if you're staying at one of the nearby caravan parks - Sandhills, Kinghorn Harbour, or Pettycur Bay - they're worth a quick detour on foot or a short drive. What remains is honestly modest: crumbling stone walls that once formed a 16th-century fortified house, the kind of defensive structure that dotted Fife when the Forth was a genuine border to defend.

You won't spend hours here. Twenty minutes to half an hour if you poke around the ruins and try to work out the original layout from what's left standing. The setting is pleasant enough though - open ground around it, decent views towards the Forth if the weather cooperates. Local history buffs will get more from it than casual visitors; kids might find it underwhelming unless they're into clambering over old stonework.

Free to visit, naturally, since there's no formal visitor infrastructure. Just turn up. It's the sort of place you'd factor into a longer walk around Burntisland rather than make a special trip for, but if you're already camped at Sandhills or Kinghorn Harbour and fancy something to do between beach time, it's genuinely local and requires minimal effort. The ruins won't blow your mind, but they're there, they're old, and they're close by. Sometimes that's enough.
