This island is a protected natural site with important local fauna and flora. Learn the history of a naval hospital in a unique building from the XVIII century, and the remains of a Paleocristian Basilica from the VI century. Take a boat to Isla del Rey, and join one of its tours that are held by volunteers in both English and Spanish.

Even if ancient ruins aren't your cup of tea, a trip to an archaeological site is worth the detour. The journey will take you through the quaint countryside, threading through small towns and villages that might otherwise escape your notice. Just a few kilometres from the holiday resort of Altinkum, in Yenihisar, you'll find Didyma — home to a grand temple dedicated to Apollo. Didyma was more than a religious site; its oracle rivalled the fame of Delphi's. While the original temple was destroyed by the Persians around 400 BC, the existing ruins hail from the Roman times. The remnants of 120 columns stand as testament to the temple's once monumental size.

Testament to the grandeur of ancient Halikarnassus — present-day Bodrum — the amphitheatre dates back to the 4th century BC and boasts a breathtaking view over the Aegean Sea. This Bodrum landmark, among the best-preserved structures of its bygone era, is conveniently within walking distance from the city centre.

The entire trip of 2,000 miles (3,220 km) starts in the tropics of the Northern Territory, in Darwin and leads you through the red desert and Alice Springs, all the way to the green and plentiful province of South Australia and its capital Adelaide. The trains are comfortable and equipped with a dining car; many off-train experiences at stopovers are included in ticket prices.
