About Kathmandu
Kathmandu is Nepal's chaotic capital and the gateway to the Himalayas — trekking to Everest Base Camp, Annapurna Circuit, or mountain flights. The city itself is dusty, loud, and the pollution is rough, but the temples (Swayambhunath, Pashupatinath) are stunning. The food is dal bhat (lentils and rice) on repeat.
- •Swayambhunath (Monkey Temple)
- •Pashupatinath Temple (Hindu cremation site)
- •Boudhanath Stupa (Tibetan Buddhism)
- •Thamel district for trekking gear and backpacker bars
