The water is usually a bit muddy; exposure to the open ocean can stir up the bottom
From town (Isabel II), take main street (Calle Muñoz Rivera) north toward the water. Just before the dead end, turn left and go one block. Then turn right toward the water and follow the curve to the left. There is a very small parking area here near a hand-painted sign for Seaglass Beach. You must park at the top of the hill, there is no parking down the hill so if necessary, retrace your steps and find street parking in town within a block or two. The beach is down the steep hill.
Sea Glass Beach is a small beach right in the town of Isabel II. It’s claim to fame is seaglass of course, but it also has nice views of the Isabell II harbor, and across to mainland Puerto Rico. The beach is shallow in that it is almost non-existent during high tide.
