Top 9 unusual Discovery tours

Travel across the Gobi desert, one of the most remote places on earth, and marvel at the scenery. There are no roads or tracks to follow, making this truly off-the-beaten-track, but you'll be in safe hands with your expert driver. Finish up at a traditional ger camp, where locals will invite you to share a drink of airag or koumiss (fermented mare's milk).

Travel along the 25 tunnels road - a deeply dramatic road of tight hairpin bends that descends hundreds of metres in a short time, to the 600 year-old marble village of Thee Ain. The mysterious-looking set of stone houses, originally built as a citadel on top of a white marble outcrop, are surrounded by banana plantations, fruit trees and mountains. The 8th-century construction is visually magnificent from afar, and fascinating close up. We'll have a delicious al fresco lunch in a calm and shady spot, in the shadow of the mountain village.

From hanging coffins and mysterious burial caves to horse-drawn carriages and colonial cities, this exciting tour explores an area quite unlike any other South East Asian destination. Visit 2,000-year-old rice terraces built by the Ifugao people. The fertile land makes these terraces a vivid green colour - a striking sight when contrasted with the blue sky. 

Visit one of Africa's least-explored countries and discover its unique history and natural wonders. Travel by 4WD past camel caravans into the other-worldly landscapes of the Danakil Depression, a vast desert plain dotted with bright yellow, green and red acidic pools, giving the feel of another planet. 

Travel through Madagascar in search of amazing wildlife and spectacular scenery. Take a night-time walk in Andasibe Reserve by torch-light to spot chameleon and the smallest primate in the world – the mouse lemur. Visit Antsirabe in the Central Highlands and witness its colonial architecture, colourful rickshaws and souk-like stalls; an unexpected hybrid of cultures.
