1. Chitwan National Park
Chitwan park is the place to come back to experience a unique side of Nepal, aside from the hiking and therefore the intrigue of Kathmandu. This is the place for wildlife views and a safari-type environment. At an altitude of only 100 meters in some areas, much less than Kathmandu at 1400 meters, this area features a tropical monsoon climate, usually quite different from what most people expect to find in Nepal.
Visitors come here primarily to see wildlife. Tours from the lodges take visitants out into the park, either on foot or mostly on elephants for close-up views of the animals. The park is home to rhinos, Bengal tigers, leopards, sloth bears, gaur (buffalo) deer, and lots of other critters. Freshwater dolphins and crocodiles populate the rivers and streams but are unusually seen. More than five hundred species of birds make Chitwan National Park a paradise for ornithologists.
2. Trekking in the Langtang Region
It is a pleasant area for hiking, great views, old monasteries, and delightful mountain scenery with rhododendron forests that bloom during the spring hiking season. It is underdeveloped than a number of the other popular trekking areas in Nepal and usually less busy on the trails, despite its proximity to Kathmandu. There are villages with guesthouses and food right along the route, although somewhat more opened up than in other trekking regions.
3. Swayambhunath (Monkey Temple)
Set on a hill to the west of Kathmandu, Swayambhunath is that the second most vital memorial within the Kathmandu Valley after Boudhanath. Due to the resident monkeys that inhabit parts of the temple, it's more affectionately referred to as the Monkey Temple. The Swayambhu Stupa, painted with the eyes of the omnipresent God, forms the centrepiece of the temple complex. It was originally an ancient religious site, but the temple complex dates to the 5th century. Swayambhu plays a serious part within the lives of the Vajrayana Buddhists of northern Nepal and Tibet, but especially of the Newari Buddhists of the Kathmandu Valley.
