We need rockpools, but not UK or Brittany - any ideas?

[NQWWW]

We are 2 families going away together, and we've all been to Devon & Brittany several times already. We're looking for a (pretty-much) guaranteed sunny holiday with sandy beaches and rockpools to keep my ds entertained.

Don't really mind where - southern France? Spain? Anywhere not too far? I was thinking Croatia might be nice but most of the beaches there seem to be pebbles or concrete.

Please help!

corsica? north west spain also good, but weather less reliable

Good rockpools on the Western Cotentin peninsula of Normandy - Barneville Carteret
But not guaranteed hot sun

Ibiza, only 2.5 hrs flight

Es Cana

Lovely sandy beach

Rock pools

Snorkelling along rocky shoreline, sea is very clear and turquoise

within walking distance there is also another beach with waves that are rough enough for body boarding and beautifully picturesque and sandy

only problem is, the pound is crap agaisnt euro but if you go all-inc this is not such a problem

the Miami Ibiza hotel sits right on the beach. You can sit at the pool bar and watch the kids on the beach

At least one of the beaches at Bretignolles in the Vendee has rock pools + sandy beaches + dunes for sliding down. We have had great weather there for the past few years. (Fingers crossed for this summer!)
