Yes — Bengaluru is generally safe for tourists, including solo women travellers, and is one of India's more internationally accustomed cities. Standard urban caution is all that is needed.
Transport: Use Ola, Uber, or the Namma Metro rather than unmarked or unmetered auto-rickshaws, especially after dark. The metro is clean, punctual, and covers most tourist areas.
Traffic: Bengaluru's traffic is notoriously heavy — factor in extra journey time during peak hours (8–10 am and 5–8 pm) and avoid renting a car unless you have experience with Indian road conditions.
Areas to note: The city centre (MG Road, Indiranagar, Koramangala, Whitefield) is well-lit and lively after dark. Some older market areas (Shivajipet, parts of Old Bengaluru) are best explored in daylight.
Health: Tap water is not safe to drink — stick to sealed bottled water. Street food is generally fine from busy, high-turnover stalls, but exercise judgement in quieter spots. Mosquito repellent is advisable during and after the monsoon.
Emergencies: Police helpline 100; tourist police at major landmarks. Keep a photocopy of your passport and e-Visa confirmation separate from the originals.
