Samana , Cayo Levantado is beautiful
Also, the 27 waterfalls, very fun!!!
There is a dolphin place nearby , where you can closely interact with them and learn a lot about them .
There’s the “teleferico de Puerto Plata” which takes you to a statue of God on a very high elevation almost right next to the clouds, the temperature drops significantly once you get up there.
and yeah Cabarete is fun .
