Long Hut

Stone foundations sprawling across a Welsh hillside mark the remains of what was once the longest Neolithic house discovered in Wales. Long Hut lives up to its name - this 40-metre structure would have sheltered an extended family around 5,000 years ago, making it older than Stonehenge.

The site sits on open moorland between Conwy and Llandudno, accessible via a proper walk that's not for pushchairs but manageable for anyone with decent shoes. What you'll find are low stone walls outlining the rectangular building, with information boards explaining how these early farmers lived. It's free to visit, though parking can be limited on the narrow approach road.

History enthusiasts will appreciate the significance - this is one of Britain's most important Neolithic sites. Families with older children who can handle the terrain might find it interesting, but toddlers will get more from a castle visit. The exposed location means weather matters; come prepared for wind and rain.

Allow an hour including the walk from the road. Best combined with other attractions around Conwy rather than making it a destination trip. Several holiday parks including Hafan y Gogarth and Aberconwy Resort make decent bases for exploring this corner of North Wales, though you'll want backup plans for when the weather turns.
