Bryn Castell

Stone foundations peek through the bracken on this windswept hillside just outside Conwy, marking what was once an Iron Age hillfort. The remains are fragmentary - low walls and earthwork banks that require a fair bit of imagination to picture as a thriving settlement 2,000 years ago.

History buffs will appreciate the setting more than casual visitors. The site commands proper views across the Conwy valley, and you can see why ancient Celts chose this spot for defence. Kids might find it a bit dull unless they're into scrambling over old stones and playing archaeologist.

Getting there involves a decent walk uphill from Conwy town centre - allow an hour each way if you're taking your time. The path can be muddy after rain, so come prepared with decent footwear. There's no visitor centre or interpretation boards, which keeps it peaceful but means you'll need to do your homework beforehand.

For families staying at nearby holiday parks like Conwy Holiday Park or Wern Farm Caravan Park, it makes a good morning expedition if the weather's decent. Combine it with a trip into Conwy itself to see the castle and walls for a proper dose of Welsh history. Just don't expect Stonehenge - this is archaeology for people who enjoy using their imagination.
