Beyond diving and fishing, the bay and nearby beaches offer kayaking, paddleboarding and boat tours. The neighbouring town of Cabarete is world-famous for windsurfing and kitesurfing.
The protected cove at Sosua keeps water gentle, which is great for relaxed paddling and swimming close to shore.
We went here last winter and it was exactly like you describe. The water really is that clear!
Great little guide, thanks for putting this together.
