On holiday in Tossa de Mar, Spain, last year, we bought basic mask-and-snorkel sets, because the conditions there are ideal – crystal clear waters, and a sharp drop in the seabed which means there's deep water rtight up to the shoreline, allowing shoals of fish to swim right up close to the beach.
We loved it, and we're keen to keep on with our new "toys". Where in Italy is good for snorkelling? And what would conditions be like in September? Chilly, or not? Thanks
