PEDN VOUNDER BEACH, Cornwall, [ENGLAND] Romantic moments with the husband. One of the most stunning tidal beaches in Cornwall Pedn Vounder is hidden at the bottom of a challenging, vertiginous cliff path. Not for the faint-hearted the route begins in the village of Treen. Walk past the campsite through heather and gorse shrub land and begin a rocky descent to the beach below. The beautiful lagoon is more than worth the effort.
