It is only a short walk down the path from the National Trust car park though I found it rather depressing that for such a beautiful spot and for the fact that there were several NT wardens hanging about at the car park and there is a cafe on the beach there was an extraordinary amount of litter.
The beach has 2 bays. The one with the cafe (and signs warning of tides, rips etc. and suggesting you don't swim) is very enclosed with a gently shelving sandy beach and various large rocks to swim from. It also fills quickly with people and will disappear at high tide.
The further bay is 'wilder' in the sense that less people go there and you can't see the cafe. Again there is a wide sandy beach but with the bonus of several caves to explore. The water is clear greeny-blue and we had the company of a cautious seal. The sea off this bit of the beach is a good deal more sheltered so even with large breakers hitting the main beach we had a bumpy but unstressful swim.
