When preparing for your trip to Kathmandu, consider a few practical tips to enhance your experience. First, connectivity is essential; you can easily purchase a tourist SIM card at the airport, which is located between immigration and customs. This will help you stay connected throughout your stay. WiFi is widely available in hotels, cafes, and some public areas, making it convenient to access information and stay in touch with friends and family.In terms of local customs, it's polite to greet locals with 'Namaste' and use your right hand when giving or receiving items. Dress modestly, especially when visiting religious sites, by covering your shoulders and knees. Tipping is appreciated in restaurants for good service, while rounding up taxi fares is a nice gesture.For packing, lightweight clothing is ideal for warm days, but don't forget warmer layers for cooler nights. Essential items include a reusable water bottle, sunscreen, and a power adapter for Nepal's electrical outlets (Type C and D). If you plan to trek in higher elevations, consider altitude sickness precautions. These tips will help you navigate Kathmandu with ease and respect its culture.
