Location
A secluded 100-feet-deep freshwater pool so pristine that it glimmers with a shade of cobalt blue. Might be paradise but in fact it is Dudu Blue Lagoon. The water is really blue and clear and with a soft sand bottom, the place is perfect for swimming and snorkeling. The lagoon also features underwater caves, making it a popular scuba diving destination.
Several tours include a stop at this site along with visits to a plantation and several popular beaches. But, if you want to go straight to the lagoon and spend as much time as you'd like, you can hire a cab to drive you there and wait until you're done. Cab will be roughly $20-50 US per person, depending how well you negotiate.
Entrance fee: 100 Dominican pesos per person. Costs of getting there will be higher.
