A short day trip south of the Azerbaijani capital, Baku, sit two rather different attractions. One of the particularly odd natural phenomenon is the mud volcanoes. With the majority of Azerbaijan's nearly 700 mud volcanoes (over half the number in the world), Gobostan is a great place to see the bubble-bubble action. Although not for bathing, simply wandering around the other-worldly landscape is worth the trip in itself. But, sharing the site is the UNSECO listed Rock Art Cultural Landscape. On the plateau overlooking the mud volcanoes are some 4,000 rock carvings covering 40,000 yeas of rock art. Gobostan is a rare chance to see both natural and man made wonders with having to wander too far.
