Playa Sucia, Cabo Rojo
Around October and November, you may see areas cordoned off where sea turtles have laid their eggs. And during the low season, if you go on a weekday, you may have some time when you have the entire beach to yourself; the crowds are bigger on weekends and during the traditional spring break months of February and March. During those times you may be able to buy helado or a freshly made mojito.
The surf depends on the time of the month and the weather, but it is always kind. As stated, it is very rustic, so there are no picnic tables, benches or restroom facilities—plan accordingly. There are trash receptacles at the start of the trail to the beach, so bring some bags. There are no fees for parking or entry.
