The island tower stronghold of Archibald the Grim, reached only by a small boat across the River Dee, when the boat is running. Reviewers report the crossing has been out of action for stretches recently, but the surrounding nature reserve, with well-kept mobility-scooter-friendly paths and resident ospreys, makes the walk worthwhile even without getting across to the island itself.
Worth the trip
The boat crossing to the island — when it's operating, reviewers rate reaching a genuinely island-bound tower as a rarer experience than most Scottish castles offer.
Before you go
The boat service isn't guaranteed to be running, so have a backup plan for a castle-viewed-from-the-bank visit — the nature reserve walk is well maintained enough for mobility scooters, and reviewers report osprey sightings from the lookout post even without crossing.
A recurring theme across these reviews is that visitors were unable to cross to the castle itself — whether because of ongoing works, the boat being out of service, or accessibility limits — so the visit often becomes a walk through the nature reserve to view Threave Castle from across the water rather than an on-site tour. Even so, most still enjoyed the walk, wildlife (including nesting ospreys) and views, though one visitor was frustrated at finding yet another Historic Scotland site closed with no indication of when it might reopen.

“Nice looking castle from afar unfortunately the boats were off the day wee went, lovely surroundings though had a nice walk round.”— Tam Laffey, visitor review
