Packing & Clothing: Bring layers for January—warm daytime layers, a good insulating jacket for mornings/evenings in Kathmandu, sun protection for high-altitude treks, and comfortable walking shoes. Health & Altitude: Stay hydrated, plan a slow ascent if trekking, and consider altitude medication if heading above 3,000 m; seek advice from a travel clinic before departure. Flight & Weather Contingencies: From Raleigh-Durham International Airport (RDU), monitor winter forecasts and choose flexible tickets with waiver or travel insurance; keep digital copies of travel documents for quick rebooking. Money & Connectivity: Carry some local currency on arrival at Tribhuvan International Airport (KTM) and buy a local SIM or portable Wi-Fi if you need reliable maps and communications. CTA: Use this January checklist to prepare your RDU to KTM journey, and finalize flight and transfer bookings well in advance to avoid winter-season disruptions.
