Amos is a 2,500-year-old city on a hilltop above Kumlubük Bay, about 25 kilometers from Marmaris. The site was positioned to watch maritime trade routes and defend against raids, and that strategic logic is exactly what makes it worth the climb today: the ruins look out over bays, pine-covered islands, and open sea in one of the better panoramas on this coast. What survives includes sections of city wall, building foundations, and scattered architectural fragments, with evidence of occupation running from the Classical period through the Byzantine era. The walk up passes through Mediterranean scrubland and old olive groves, moderately steep but short, and the site's isolation has kept both the archaeology and the quiet intact. Go early or late to avoid the heat, carry water, and swim at Kumlubük Beach below afterward.

Marmaris has been a strategic harbor since the Hellenistic period. The castle was rebuilt by Suleiman the Magnificent in 1522 for his campaign against Rhodes. Ancient traders and modern yacht crews have used the same sheltered bay.

Visitors interested in Greek ruins and Ottoman fortifications will want a few hours here. The castle photographs best from the harbor in the late afternoon.

First-time visitors and solo travelers both manage easily here. The area is walkable, and staff at most sites are used to tourists.

Most Marmaris attractions are easy to reach from the bay. Netsel Marina sits next to the castle quarter, and İçmeler beach is a short dolmuş ride from the town center. Restaurants around the harbor serve fresh seafood.

Bazaars near the harbor sell Turkish crafts and souvenirs. Waterfront cafes are a good place to try Turkish tea between stops.
