Running from the edge of Porthkerry Park to the promontory known as 'Cold Knap', this is a popular beach for dog walking and with wind-surfers. It's very pebbly, but is used by intrepid bathers in the summer. There is good fishing from the rocks at the far end of the beach, on the promontory itself. At high tide, it's quite steep, although there is a shingle/sand stretch revealed at low tide.
Situated on the Bristol Channel, this stretch of coastline has the second highest tidal range in the world, at about 15m, so it really does go up and down. (It goes without saying, therefore, that you should be careful about not getting cut off under the cliff at very high tides).
There's a large, free car-park at the foot of the cliffs, a favourite place for showing off souped-up Ford Escorts in the evenings. In summer, there's an ice-cream van as well. Porthkerry Park can be reached 0.5km along the beach if you are reasonably fit, and the tide is out, although it can be hard to walk on the larger pebbles and rocks.
The cliffs and rock formations on the beach offer a text-book example of horizontal sedimentary geology, and are amazing to look at. In various places there are sea-cut caves, although given the propensity of bits of cliff to tumble down from time to time, it is not recommended that you get too close to the foot of the cliff itself.
The beach also has some rock pools, although the tides and waves mean that they are not the most interesting - although you can find the odd hermit- and shore-crab if you are persistent, and perhaps a small fish or two. It's a favourite with beach-combers, too.
Above the beach, the green by Marine Drive offers spectacular views across the Bristol Channel to the islands of Steep Holm and Flat Holm, and the Somerset coast, 15-20km beyond. There's always plenty of shipping to watch too, heading up- or downstream, or simply waiting for the tide to take them to the docks at Bristol, Newport, Cardiff, Barry or Sharpness. read more
