Corbett is one of the few parks where it is possible to stay inside the park in government run guest houses. We spent one night at Birjani government guest house which was undoubtedly the worst accommodation we have ever stayed in. The guest rooms had been recently renovated and there were piles of building rubble and even worse piles of rubbish and litter everywhere - completely unacceptable in a national park. But, worst of all were finding filthy sheets on the beds. The sheets were also too small for the beds, there were no top sheets, available and the mattresses were either really dirty or covered in plastic. There was also no hot water. It was cold and damp and it was quite clear that the staff do not have the facilities to do laundry and get it dry and also do not have enough supplies of linen.
