Poldhu Cove

The walk down to Poldhu Cove takes longer than you'd expect, but stick with it. This is where Guglielmo Marconi sent the first wireless signal across the Atlantic in 1901, and the beach itself rewards the effort with a proper stretch of golden sand backed by low cliffs. It's not one of those Instagram-famous Cornish coves - you won't find crowds fighting for space - which is exactly why it's worth the trip.

The cove suits families and walkers equally well. There's a cafe at the top which helps break up the descent, and the sand is decent for building castles or just stretching out. If you're into maritime history, the remains of the old wireless station are still visible, though they're not much to look at. The real draw is the sense of space and the quieter vibe compared to places like Perranporth or Constantine Bay further north.

Give yourself a good two hours here if you're swimming. The water's cold even in summer - proper Atlantic temperature - and the beach has that slightly isolated feel that makes you want to linger. Bring a packed lunch; the cafe is fine but limited.

If you're based at Henry's Campsite, five miles away, this is a straightforward morning or afternoon trip. Park near the cove entrance and walk down - there's nowhere to leave a van right by the sand. Low tide is better for space, though the cove works at any state. Worth the detour if you're doing a Cornish tour, though not a destination in itself.
