CNN-Would you travel halfway across the world by bus?

Expedition company Adventures Overland is hoping you'll say yes to its new organized bus trip, which will ferry travelers from the Indian metropolis of Delhi to the UK capital of London -- no airplanes involved.

Described as the "first-ever hop-on/hop-off bus service" between the two destinations, Bus to London will ferry 20 passengers on a modified luxury bus, inspired in part by the Hippie Trail buses that crisscrossed the world in the 1950s and 1960s.

The bus will cross 18 countries over a period of 70 days, with passengers hopping off to marvel at the pagodas of Myanmar, hike the Great Wall of China and wander historic cities including Moscow and Prague.

Adventures Overland was founded by entrepreneurs and enthusiastic travelers Tushar Agarwal and Sanjay Madan.

Agarwal tells CNN Travel the idea was inspired by an incredible solo drive from London to Delhi he did back in 2010.
