Mumbai is India's financial and entertainment powerhouse. It is generally considered safer and more progressive for female travelers than northern Indian cities, and locals are often very helpful. The main tourist areas in South Mumbai (Colaba, Fort) are heavily policed. The biggest physical risk in Mumbai is the local train network; the trains are dangerously overcrowded during rush hour, and tourists should avoid them at peak times to prevent injury or aggressive pickpocketing. If you plan to take a slum tour (like Dharavi), ensure it is through a highly reputable NGO or tour group. Environmentally, Mumbai experiences a brutal monsoon season from June to September, which frequently causes severe, paralyzing urban flooding.
