The beaches closest to town are not the best in the island, but they’re good enough for a swim and getting a bit of sunlight. That being said, we recommend you rent a bike/car and go to the best spots (most of them aren't even accessible by bus).
ammoudara: by far the easiest option. Just get bus number 6 from ‘Kamaraki’, and you’ll be there in less than 20min. Lots of bars and restaurants around.
karteros: the locals favourite. Buses 11 & 12 will get you there in less than 30 minutes from ‘Kamaraki’.
if you do get a car, check out these incredible places around the island:
agiofaraggo - combines beautiful scenery and crystal clear waters. Perfect spot for hiking, climbing, and swimming.
matala & komos - Matala was a sleepy fisherman village in the south that became a hippy paradise in the 60’s and retains a lot of the charm and character. Komos is the nudist sandy beach right next to it - perfect for wild camping.
triopetra - very esoteric and high in energy. A favourite beach for meditation, yoga etc.
preveli - Venetian monastery, palm tree forest, river, sandy beach, crystal blue waters. Paradise?
spinalonga - the leper island
chrissi - the golden island
vai - palm tree forest beach
kouremenos - international windsurf hotspot
balos - the most famous and photographed beach on the island
falasarna - huge sandy beach in the west coast
