swimming
There are beaches, both sandy and shingle, all around the coast so swimming and sunbathing are popular activities. The water is very clear but cold up until May. The nearest major beach to the town of Samos is Gagkou Beach, a fifteen minute walk with the sea on your left from the ferry port. This is a pebble beach but there are areas of sand in the water. You can rent sun loungers and there are bars/cafes on the seafront although you may not be able to consume their food and drink on the beach itself.
Samos has excellent watersports facilities to be found on the long pebble beach at Potokaki which are open all season. Including waterskiing, inflatables and jetski hire.
coastal path
Walk the coastal path from Gagkou Beach see above for directions through beautiful flora and see the crystal clear coves. From Gagkou beach head over to the half-finished concrete building. Head up the steps of this, cross the first floor and you'll see a path off into the heather from here. You can follow this path for a couple of kilometres until it leads you back to the road. It's a great place to watch the sunset and you can get down to one or two deserted although very small beaches via this path.
