Asia's wild frontiers the new adventure travel hotspot?

South east Asia adventure tours to the region's more remote areas are becoming an increasingly popular holiday choice, the New York Times reports.

According to the newspaper, while Asia has long been a destination of choice for those looking to explore bustling cities, enjoy world-class cuisine and visit ancient temples, the continent's wild frontiers are increasingly being added to the must-see list of more adventurous travellers.

Rural and remote areas of countries such as China, India and Cambodia offer visitors some of the most stunning natural landscapes anywhere on earth as well as the chance to spot an incredible array of wildlife.

Visiting wildlife sanctuaries in the southern wilds of Thailand, spotting tigers in the hills of India and tracking pandas in China are just some of the newly available experiences attracting tourists, the newspaper reports.

The northern plains of Cambodia are also becoming an increasingly popular destination, particularly for wildlife lovers.

This remote and sparsely populated region is one of the few remaining places in Cambodia where visitors can spot animals such as Asian elephants, leopards and wild cattle.

It is also home to a number of rare bird species like the giant ibis and the white-shouldered ibis.

The Wildlife Conservation Society has been working with the Cambodian government to protect the area and the animals that live there.

"People see a few temples and then want something else," Joe Walston, executive director of the Asia program for the Wildlife Conservation Society, told the newspaper.

"Birders have been coming for a few years," he said, but added that the northern plains are beginning to open up to a greater array of tourists.

"It's still relatively rustic [but] if they want the feel of being truly out in the wild, then this is it."
