Lankaran is generally safe for solo female travelers, with low crime rates and few reports of incidents targeted towards women. However, it's always important to practice common travel safety precautions. Women should feel comfortable exploring during the day, but it's recommended to avoid secluded areas and stay in public, well-lit areas at night. Also, consider taking cabs after dark. The locals are friendly, but keep in mind that English is not widely spoken outside the main cities. Always respect local customs and dress modestly to avoid unwanted attention.
