Dominical is predominantly safe for solo female travelers. The locals are friendly and always willing to help, and the town itself is relaxed and peaceful. The primary concern would be petty crime such as bag-snatching or pickpocketing, as in any tourist location, so keep an eye on your belongings at all times. Avoid isolated areas, especially at night, and use common sense while drinking or swimming in less crowded areas. Always keep emergency numbers and hotel address handy.
