A distinctive feature of Phang Nga Bay are the sheer limestone karsts that jut vertically out of the emerald-green water. James Bond Island and Koh Panyee are just two of the more famous spots in this bay. By far the best means of enjoying the spectacular scenery, with only brief encounters with the tourist crowds at James Bond and Koh Panyee, is to take one of the boat trips from the northern end of Phuket.
Cappadocia is a stunning region of rock formations, subterranean churches and underground cities, the scale of which is simply overwhelming. There are hundreds of underground buildings in the region. Two of the most unmissable are Kaymakli, which has eight levels, and Derinkuyu, which descends some 55 metres. Nevsehir, the capital of Cappadocia, is a great place to base yourself when visiting.
