Once a busy port Portreath is now a quaint Cornish village with beautiful sandy beach, and a narrow harbour on the north of the bay. There are rugged cliffs in both directions and the beach can at times catch very big swell.
If the conditions are ok its a great beach to swim in clean waves, although be careful if swimming out back as the currents running along the coast can be strong. You can check out my guide on swimming in waves here.
Theres a white ‘Pepperpot’ on the cliffs to the north which is a useful marker when in the water. It used to be a coastguard lookout but has now been blocked off, worth a walk up to it as the views are stunning.
