Caer Dane

Ancient earthworks rise from the Cornish countryside near Perranzabuloe, marking what was once a proper Iron Age hillfort. Caer Dane sits on elevated ground, its defensive banks and ditches still visible after more than two millennia - though you'll need to use your imagination to picture the timber palisades and roundhouses that once crowned these ramparts.

Walking the perimeter takes about twenty minutes, and the views across the surrounding farmland are lovely on a clear day. History buffs will appreciate the site's strategic position, chosen by Celtic tribes who knew a thing or two about defensive terrain. The earthworks aren't as dramatic as some of Cornwall's better-known hillforts, but there's something rather special about having the place largely to yourself.

Families staying at nearby holiday parks like Haven Perran Sands or Monkey Tree will find it a decent hour's diversion, though younger children might lose interest once they've scrambled up the banks. Best combined with a longer walk or cycle ride through the area - the site connects to several footpaths that thread through this quiet corner of mid-Cornwall. No facilities here, so bring water and check the weather before setting off.
