When travelling to Delhi, there are certain things you need to specifically carry due to the weather, road conditions, etc. Here is a list of things to keep in mind while packing:
Comfortable clothes – to suit the sultry weather
Flip-flops and shoes – walking on the streets of Delhi is not the same as walking elsewhere. You are going to have people stepping over your feet and tearing apart your footwear while street shopping or eating. Get a pair of sturdy shoes and flip flops.
Scarves and sunscreen – To protect your skin from the scorching sun.
Digestive first aid – Just in case, you are up for some serious roadside food stalls.
