We stayed just outside Skala at Mounda Bay - which had the best beaches in Skala - very quiet, sandy beach which shelved gently into the sea which was just round the corner from Skala beach (past the nudist beach). Although Skala beach itself was much livelier with lots of watersports - it was made up mainly of pebbles & shingles.
The nighlife in Skala centered around the main street which consisted of many restaurants, a few bars which closed around midnight but there were one or two nightclubs if you looked hard-enough, there was also a handful of Supermarkets and gift-shops and car-hire/excursion/exchange shops (no bank in Skala but one "tempremental" cash-machine. I would say the resort is suitable for couples & families (if you're looking for all-night revelling then Skala is not for you !). All the local people were very open, honest and friendly and resort also attracts Greek families from the mainland. We would defintely recommend Skala to anyone considering a holiday here, and we would definitely go back again.
