Delhi

Use the Metro Wisely**: The Delhi Metro is one of the most efficient ways to navigate the city. Purchase a smart card for convenience, and travel during off-peak hours (before 8 AM and after 9 PM) to avoid the crowds. Note that some metro stations have strict security; keep your bags organized for quicker entry.

Explore Local Eateries**: While famous restaurants are great, don't miss the local dhabas (roadside eateries) and street food stalls. Head to Chandni Chowk for authentic dishes like parathas and chaat. Always check if a place is busy with locals—it's usually a good sign of quality and hygiene.

Dress Modestly, but Comfortably**: While Delhi is relatively liberal, dressing modestly is appreciated, especially in religious sites. Choose breathable fabrics like cotton to stay comfortable in the heat and humidity, especially when exploring outdoor attractions.

Plan for Pollution**: Delhi's air quality can be poor, particularly in winter. Consider wearing a mask if you're sensitive to pollution, and check air quality indices daily. If you're planning outdoor activities, try to schedule them for early mornings when the air is usually clearer.

Negotiate with Caution**: If you’re using auto-rickshaws or taxis, always negotiate the fare before starting your journey unless using a metered service. For a hassle-free option, use ride-sharing apps like Uber or Ola, which provide upfront pricing and avoid the need for negotiation.

Cultural Etiquette at Temples**: When visiting religious sites, take note of the customs. Always remove your shoes before entering, and be prepared to cover your head in Sikh Gurdwaras. It’s respectful to keep noise to a minimum and maintain the sanctity of the space.
