A contender for the oldest standing castle on the Scottish mainland, its plain curtain walls rising incongruously from the middle of a static caravan park on Loch Sween. Free and unstaffed, it rewards the drive in more than the site itself - reviewers say the setting, not the ruin, is the main event.
Worth the trip
Its age - reviewers point to Castle Sween as a serious contender for the oldest standing castle on mainland Scotland.
Before you go
You can't drive right up to it - expect to park on the road and walk down, roughly a quarter of a mile, unless you're staying on the Ellary estate itself - and keep an eye on the water on the way in, as reviewers report seal sightings from the shore.
Based on a modest number of reviews, visitors appreciate Castle Sween for its history and scenic setting, reached by a short walk from parking near a holiday park. One reviewer felt its location within a busy caravan park slightly detracts from the experience, and another notes there isn't a huge amount to actually do once you're there, though the drive and surroundings are still rated worthwhile.
Free; possibly Scotland's oldest standing castle
“Lovely old castle potentially the olds castle on main land Scotland, Short walk through the caravan park, some parking provided”- Richard Harris, visitor review
