About Kathmandu
City overview
Kathmandu is the dense Kathmandu Valley capital, where Thamel guesthouses, Durbar Square palaces, Boudhanath, Swayambhunath, Patan, and post-2015-earthquake reconstruction all sit amid traffic and temple courtyards. The practical map is Thamel for logistics, the old city for heritage, Boudha and Pashupatinath to the east, and Patan or Bhaktapur for deeper valley days.
Food & drink
Kathmandu food crosses Newar, Nepali, and Tibetan tables: momos are steamed or fried dumplings, khaja sets pair beaten rice with spiced meat, beans, pickles, and potatoes, and yomari are rice-flour dumplings filled with molasses or sesame. Asan markets, Thamel cafes, Boudha rooftop restaurants, Patan courtyards, and Bhaktapur yogurt shops add dal bhat, thukpa, sel roti, chatamari, bara, Tibetan bread, and masala tea.

Neighborhoods
1Thamel
Thamel is noisy, useful, and traveler-focused, with hotels, trekking shops, cafes, bars, money changers, and constant traffic in tight lanes.
2Old Kathmandu and Asan
The old city is dense and ceremonial, with markets, courtyards, shrines, Durbar Square, Newar houses, and earthquake restoration work.
3Boudha
Boudha is Tibetan Buddhist and monastery-focused, with the stupa, prayer circuits, butter lamps, rooftop cafes, and quieter guesthouses.
Day trips
15km / 45min-1h by taxi or bus from central Kathmandu
Bhaktapur
The brick city has Durbar Square, Nyatapola Temple, pottery lanes, and juju dhau yogurt, all better with a full slow day.
7km / 25-45min by taxi across the Bagmati from Thamel
Patan
Patan Durbar Square, the museum, courtyards, and metalwork shops are close enough for a half-day but worth longer.
32km / 1.5-2h by car from Kathmandu
Nagarkot
The ridge town is used for Himalayan sunrise views when haze and weather cooperate. Overnight stays improve the odds.
Getting around
Taxis, ride-hail where available, local buses, tempos, and walking handle the valley, but traffic, dust, and narrow streets slow everything. Keep Boudha-Pashupatinath, Durbar Square-Thamel, and Patan-Bhaktapur as separate clusters rather than crisscrossing the valley all day.
