Among the better-known beaches of Samos is gorgeous Megalo Seitani, which can be accessed either by foot along a trail some 3.5 km from Karlovassi Potami, or by a tour boat from the harbor at Karlovassi; this option has a distance a bit farther, at 6 km. This is a sandy and wide beach with crystalline, deep waters set in an ever-green landscape.
Megalo Seitani is sometimes frequented by clothing-optional enthusiasts, but her main attraction is the monachus-monachus seal, which makes its home here. This beautiful, peaceful sea animal gives the beach and surrounding area important ecological significance (a National Wildlife Refuge and Park), and is followed and admired by thousands of wildlife supporters and fans each year. Unfortunately, no facilities or other tourist services are available here.
