Very beautiful island, not really on the tourist trail but the easiest to get to, as it's only a 3/4 hour trip by small boat from Piraeus , so essentially you can be on the beach within 2 hours of landing at Athens Airport.(All night ferryboats from Perama , which is a short taxi or bus ride from Piraeus if you arrive at night) The West and southern coasts have the best beaches and the main gulf of Salamis has some excellent beaches, too. Clean, clear warm water and safe for children. Not developed as a tourist destination although the population swells from 50,000 to 200,000 during the Summertime. This may seem like a lot of people, but Salamina is a large island and can absorb this volume of people. The mainland side of the island Is a bit industrial in places but none the less attractive and interesting. Lots of history dating back to the Battle of Salamis and beyond. Very Greek and very friendly, mostly made up of people from Athens and Piraeus who spend the Summers there, but more and more European tourists are finding their way . Lots of bars,clubs and nightlife. Salamina town has large supermarkets ,(Lidl) tavernas and everything that one would need while holidaying there. Much cheaper than the more well known Greek islands. Check out Airbnb or similar as there are not a lot of campsites. One that I know of is at Kanakia on the west of the island. it's ok but a bit out of the way.
