Marathounda Beach was the first beach we visited, as part of a trip across the island.
The beach is stoney with a small patch of sand at the north end near the path down to the beach from the road. The beach is one of the few on the island that can be driven too and is served by the taxi boats.
There is a small taverna and sun loungers with sun shades. We sat on one for a while and were not asked to pay. The taverna is small but good by all reports.
The only downside are the goats that run wild in the area. They will eat anything so it is prudent to keep a close eye on your bag, its not unusual see a goat nibbling on a hat or a towel.
