The Natural History Museum sits west of central Kathmandu, near Swayambhunath. Its displays cover Nepal's animal and plant life, with collections of insects, butterflies, birds, mammals, shells, and botanical specimens.
The presentation is old-fashioned, but the museum is useful if you want context before visiting Nepal's national parks or mountain regions. It works best as a short stop combined with Swayambhunath or the National Museum nearby.
