East of Cabarete, a limestone landscape of sinkholes and caves has produced several deep freshwater lagoons with vivid blue water. The Dudu Blue Lagoon, also known as Laguna Azul and Laguna Dudu, is the best known of them, and a full-day tour typically takes in both the open-air Blue Lagoon and the larger cave-and-cenote style Dudu. At the Dudu you climb down steps into a deep pool of cool, clear water, swim, jump from a platform, ride a rope swing and, depending on the operator, take a zip line across the water. Life jackets are provided, and guides watch over swimmers. The second lagoon is calmer and good for floating and photography, with the water shading from turquoise to deep blue. The day usually includes hotel pickup from Puerto Plata, Sosua or Cabarete, a lunch of Dominican dishes at a local restaurant and a scenic drive along the coast with stops at viewpoints and small towns. It is an easy way to see a different side of the north coast, away from the resorts, and to combine nature, swimming and a taste of rural life. Because the lagoons are fresh water and shaded in places, they provide a welcome contrast to the sun and salt of the beach, and the whole trip appeals to adventurous families, couples and groups of friends who like a bit of action without a demanding hike.
Know what you are signing up for. This is a full-day excursion with several hours of road travel, a few hours in the water and a meal. The jumping platforms and zip line are optional, so non-jumpers can float, swim or watch. The steps down to the Dudu are steep in places and can be slippery, so wear shoes with grip, and bring a swimsuit, towel and a dry change of clothes. A waterproof pouch for your phone is handy, and underwater cameras work well in the clear water.
Choose your style. Larger group tours are the most affordable and social, and the operator handles all logistics. Private tours let you set your own pace, choose which stops to make and spend longer at the lagoons, and are worth considering for families or photography enthusiasts. Check whether lunch, entry fees and the zip line are included, as these vary. Mornings are the best time to visit because the lagoons are quieter and the light is soft.
A few tips from regulars
Ask your guide which lagoon to visit first so you can avoid the busiest tour buses, take cash for tips and for souvenir stalls, and pack snacks for the drive if you are a light eater. Photographers should bring a polarizing filter or simply shoot in the morning when sunlight penetrates the water. Hand your phone to the guide only if you trust them with it, or use a lanyard pouch, and always check that the zip line harness fits snugly before you launch.
Honest limits
The lagoons can be crowded at midday when several groups arrive together, the road trip is long, and the water is cool, which some people find bracing. Heavy rain can cloud the water and close facilities, so check the forecast. Pair this day with a rest day, or with an evening in Cabarete, which is nearby, for a relaxed finish. For nature lovers who want an alternative to the beach, it is an excellent choice.
