Adaköy Marina (Antmarin İnşaat Turizm Denizcilik ve Taşımacılık Ticaret A.Ş.)

Tucked away on the quietly stunning Adaköy peninsula outside Marmaris, this boutique marina sits far from the city bustle — budget 15–20€ for a taxi in, but the seclusion is worth it. You get the full package here: boat hoist, slipway, hotel, restaurant, bar, pool, and Blue Flag beaches all in one spot. When pulling in, ask for docking assistance — the mooring lines can be tricky to handle solo.
