In Yeni Erenkoy head for Balci Plaza. Drive through treelined entrance and pass the vegetable garden to the car park at the restaurant. A nice walk from there to the beach will bring you to this lovely cove. Sandy beach, with some pebbles but you can wade out quite far and snorkel or swim. The area has sunbeds and parasols and a barbeque pit. There is also a bar with drinks manned by the restaurant owner.
The cache is a canister with new log book etc.
