Vila Velha has a moderate level of safety for solo female travelers. As in any urban area, certain precautions need to be taken. Public places are generally secure, but it's advisable to avoid remote areas and traveling alone at night. Pickpocketing and petty theft can occur, so keep your belongings secure. Stick to well-lit, populated places, use licensed taxis, and always let someone know your plans for the day for added safety.
