Answer:
UNESCO has enlisted Chitwan National Park and Sagarmatha National Park of Nepal in World Heritage Sites.
Step-by-step explanation:
Chitwan National Park is actually the first one of that kind in this country. It is only the UNESCO's list since 1984 and it covers a large area of almost 1 000 km squares.
Sagarmatha National Park is another park in this country that was on the UNESCO's list since 1979. It covers a larger area than the previous one and includes even the Mount Everest peak.
