Yes — Kolkata is generally considered one of the safer large cities in India for tourists, with a reputation for hospitality and relatively low rates of violent crime against visitors.
Petty theft: Pickpocketing can occur in crowded areas such as the metro, Esplanade, and Dakhineswar temple on festival days. Use a cross-body bag and keep your phone in a front pocket.
Transport: Use prepaid taxis from the airport or app-based cabs (Ola, Uber) rather than unmarked vehicles. The Kolkata Metro is safe, efficient, and air-conditioned — the best way to move north-south.
Neighbourhoods: Most central and tourist areas — Park Street, Esplanade, Salt Lake, and North Kolkata's heritage belt — are safe to walk day and night. Exercise standard urban caution after midnight in unfamiliar areas.
Health: Drink only bottled or filtered water. Stomach upsets from street food are the most common ailment — start cautiously with reputable stalls and build up. Mosquito repellent is advisable year-round, especially during and after the monsoon.
Solo and female travellers: The city has a strong tradition of public safety and a vocal civil society. Solo female travellers generally report Kolkata as more relaxed than Delhi or Mumbai, though standard precautions apply at night.
