You can walk there, not sure about ATV. It is a long walk from Las Galeras, maybe 1 hour. I went on horse to Playa Madama, which is close. Probably you can go on horse or get close. Get a boat at the Las Galeras beach. Make sure to go to Playa Madama also. Be careful swimming at Playa Fronton. There are some dangerous currents. I know this!! Calmer swimming water at Playa Madama. I would allow 4 hours or so for the trip. Lots to explore!!
