On the west side of Karpathos (Arkassa, Finiki, Lefkos) the sun sets which gives you an amazing uportuity for a photo moment or just a relaxing moment to enjoy the sunset.
We love this spot in Arkassa, but depending on where the sun exactly sets Arkassa Beach (Ag. Nikolaos Beach) is also a great option among other spots in Finiki and on the road towards Lefkos.
