I'd be happy to have north shore more like my 80s childhood of pebbles which gradually became sand a little way down. As my user name suggests, there's nothing wrong with a pebbley beach! However north shore has become a bit like rock climbing in parts the last 10 years or more. We used to give the beach since the turn of the century the joke name of "Llanberin Down" (clambering down) - as we tried not to break an ankle!
Our favourite bit of beach as a kid was always between Queens Road and the Arcadia, the crunch of pebbles, and finding some nice patchy sand to sit on, and at low tide a good sandy paddle (nowadays it needs to be the very extreme low tide to get any sand there). I miss pebbles, booo to rocks and stones, but i find all this talk of "restoring a sandy beach" a bit misleading - pebbles and sand was always the way.
A post card showing the beach in past times, lots of shingle and not much sand.
