The whole area of Copacabana is well connected with the whole city. Metro lines leading to the beach are L1, L4 or L2. The stop where you need to get off is Cantagalo. The subway is safe and reliable, so tourists do not have problems moving around the neighborhood. A taxi is also easily accessible. If you are planning to rent a car, it would be good to hire a driver to move around a city that is known for chaotic traffic in certain areas.
