Located in south-central Bhutan, Royal Manas National Park is the oldest national park in the country and spans three districts, Sarpang, Zhemgang and Pemagatshel. It is a direct neighbour of Manas National Park in India, a UNESCO World Heritage site, offering an unhindered flow of wildlife between the two parks. Off-limits for many years, the park has recently opened its doors to visitors but is still largely unknown so the area is very much off the beaten track. Royal Manas is home to a range of indigenous and often endangered wildlife such as water buffaloes, clouded leopards, civets, golden langurs, a small population of tigers and reportedly over 400 bird species including the Rufous-Necked Hornbill. Trekking excursions can be done in the park with accommodation in basic log cabins on campgrounds.
