Alleppey is relatively safe for solo female travellers, but like any travel destination, precautions should be taken. Since it is a popular tourist area, scams are not uncommon. Always keep personal belongings secure to avoid pickpocketing. Avoid isolated areas especially at night. Local people are generally polite and helpful but as it is dominated by a conservative society, it's recommended to dress modestly particularly when visiting religious places. Always respect local customs and traditions to avoid drawing unnecessary attention.
