Full Description & Details

Bostancı Koyu is an anchorage along the Kapıdag shoreline in the Sea of Marmara, where the land rises into woods close behind the beach. The setting is simple, suited to a swim stop with room to stretch your legs ashore. The coast track offers views across the gulf, and inland there are forest paths and picnic spots. The peninsula has cultural links to old churches, monasteries, and the Kyzikos archaeological zone.

The anchorage typically has a sandy or mud bottom, which generally offers secure holding once the anchor is set. There are no details on depth or the number of berths, as this is an open anchorage rather than a marina. You should plan to anchor and come ashore by tender, as there are no reported mooring buoys or designated berths.

Facilities on site are minimal or unreported. There is no mention of fuel, water, electricity, or shore-side services at the anchorage itself. The nearest services would be in the surrounding Kapıdag area, but specific locations are not detailed in the sources. Plan to be self-sufficient during your stay.

Safety notes are limited, but the sandy or mud bottom is a positive for holding. The best season is not specified, but the Marmara region typically has a pleasant sailing season from late spring to early autumn. There are no reported restrictions, but always check local conditions. The anchorage is best treated as a daytime or overnight stop in settled weather, given the lack of shelter details.

How to get there

Approach Bostancı Koyu from the Sea of Marmara, heading for the Kapıdag shoreline. The anchorage is one of several small coves along this coast, so use the coordinates (40.5024 N, 27.9281 E) as your waypoint. There are no reported navigation hazards or specific VHF procedures mentioned in the sources, so keep a lookout for local traffic and fish farms.

For land access, the anchorage is in Turkey, and the nearest major city is likely Bandırma or Erdek, though specific transport links are not detailed. The coast track from the beach leads to forest paths and picnic spots, and the Kyzikos archaeological zone is a cultural stop in the area. No formalities are reported for arriving by sea, but you should clear into Turkey at a designated port of entry if coming from abroad.
