Degibna - National Trust

Degibna sits on the Cornish coast as a proper slice of Iron Age history - a prehistoric fort that's been holding its ground for roughly 2,000 years. The National Trust looks after it now, and what you're actually seeing are the remnants of defensive earthworks: grassy banks and ditches that once formed a settlement perched above the sea. It's not dramatic ruins or anything - more like walking across lumpy fields with excellent coastal views thrown in.

The real appeal is the walk itself and the sense of standing where people once lived and worked. On a clear day, you can see for miles along the Cornish coastline, which makes the effort worthwhile. History enthusiasts will appreciate the chance to read the landscape and understand how ancient communities chose their spots - high ground, defensible position, access to the sea.

It's straightforward to visit: free access, no set hours, and you can spend as little as twenty minutes or take a proper ramble depending on what calls you. The ground can be boggy, so decent footwear matters. Kids might find it less gripping than a castle with towers to climb, but if they're into adventuring across headlands and spotting ruins, they'll get something from it.

The Secret Garden Glamping is only 3.5 miles away, making Degibna an easy addition to a coastal park holiday. Combine it with other nearby Cornish walks and you've got a solid day of exploring the cliffs without needing to pack a full itinerary.
