Much of the Castle of St. Peter is accessible to the public, including its courtyard, the exterior of three towers, and its ramparts, which afford spectacular views over Bodrum’s side-by-side bays. Visitors pay a single admission fee to explore the designated castle area and enjoy access to the indoor exhibition halls of the Museum of Underwater Archaeology.
Those wanting to learn more about the castle’s history and wider Bodrum can join city sightseeing tours that explore the site with a guide and include stops at other Bodrum landmarks such as the Mausoleum of Halicarnassus. It’s also possible to see the castle, and more city sights, on multi-day Turkey (officially the Republic of Türkiye) tours that include visits to destinations such as Istanbul, Ephesus, and Cappadocia. Other possibilities include multi-day Bodrum hotel-and-tour bundles that incorporate a castle visit.
