Corfu has some of the nicest beaches on the country in my opinion, which is why so many of them can get super crowded. Nissaki beach is small, and found in one of the smaller bay's on the island. You should really check it out if you're looking for something more lowkey
Mouse Island (Pontikonisi) is only a five-minute boat ride away from Corfu is amazing!! It is said have the remains of Odysseus’s ship after Poseidon turned it to stone. The beaches are stunning and there is a great view of Kanoni across the water. There is also a Byzantine chapel of Pantokrator and may have served as the inspiration for the famous painting Isle of the Dead.
The carnival in Corfu happens on the three Sundays leading up to Lent. The holiday starts on the Sunday of the Prodigal Son, which will be Sunday, February 20 in 2022! Start making your travel plans now! You can check out the carnival in Corfu City in either Liston or Spianada squares. Locals walk around in aristocratic costumes and there are great games for kids!! I highly recommend checking out!
