To travel between Delhi and Kathmandu, from the bustling cities of the Indian plains to the peace and tranquillity of the highest mountains on Earth, is one of the most beautiful and fascinating journeys in Asia. For culture, the Taj Mahal, 'the Pink City' of Jaipur and the holy city of Varanasi are the highlights. We also follow the footsteps of Buddha, visiting the sacred Buddhist sites of Sarnath and Lumbini. For nature, spotting rhino in Nepal's Chitwan National Park or the first view of the mighty Himalayas will provide lasting memories.
