Nepal is rich in wild life. The tropical jungles of the Terai preserve some of the best wildlife habitat in Asia. Out of the total geographical area of Nepal 16% is occupied by national parks, wildlife reserves and conservation areas. Jungle safari on elephant back is one of the thrilling experiences. Parsa Wildlife Reserve, Royal Bardia National Park, Royal Chitwan National Park and the Royal Shukla Phanta wildlife reserve, offer jungle safari on elephant back or jeep rides. The Terai region can get rather hot during summer months and temperate during winters. It is recommended that visitors carry cool clothes, good walking shoes, shady hat and sunscreen during the summer. The rainy season brings mosquitoes and leeches in the jungles. Mosquito repellant, anti-diarrhea tablets and anti-histamines can be handy during the summer and rainy months.
