When visiting Varanasi, it's essential to be mindful of local customs and practicalities. First, remember to remove your shoes before entering temples and sacred sites; wearing flip-flops can make this easier. For staying connected, WiFi is widely available in hotels and restaurants, particularly in the areas between Dasaswamedh Ghat and Assi Ghat. If you need a local SIM card, you can purchase one from major providers like BSNL, Jio, Vi, and Airtel by presenting your passport and a passport photo. It's also a good idea to pack lightweight, breathable clothing, especially if you're visiting during the hot months from April to June. Additionally, consider bringing a certified mask for outdoor activities due to air pollution. Don't forget essentials like a reusable water bottle, sunscreen, and a small guide or map to help navigate the narrow streets. Lastly, Varanasi operates on Indian Standard Time (IST), which is UTC+5:30, so plan your activities accordingly.
