Kathmandu
Nepal's capital is a dense, layered city of temple squares, medieval alleyways and ringing bells. The Kathmandu Valley holds seven UNESCO World Heritage sites within a short radius, making it one of the most culturally concentrated cities on earth.
Kathmandu is where most Nepal journeys begin and end. Beyond the chaos of traffic, there are hidden courtyards, living goddesses, sunrise stupas and a food culture that rewards wandering. It is the practical hub for permits, flights and gear before heading to the mountains.
Best time to visit: October to November and March to April for clear skies. Winter (Dec–Feb) is cold but crisp with great valley views; monsoon (Jun–Sep) is wet and hazy.
Getting there: Most international travelers arrive at Tribhuvan International Airport (KTM). Overland entry is possible from India (Sunauli, Kakarbhitta) and from Tibet via Rasuwagadhi when the border is open.
Recommended stay: 2–3 days, plus a buffer day before/after trekking.
Before trekking, check Nepal Tourism Board's current route-specific TIMS and licensed-guide rules and arrange required permits through the proper authority or a government-registered trekking agency.
Keep small cash for taxis, temples and street food.
Dress modestly at religious sites; remove shoes where required.
