If that is your PERSONAL assessment, fine...Just don't make it sound like it represents some sort of consensus...Those beaches may be nice but do not come close to the beaches in Playa Coson, Playa Bonita, Playa Las Ballenas, Playa Ricon, Playa Valle ......
You may also want to learn about what makes a beach a good one...the normal criteria used.
These criteria favour strongly the beaches I mentioned over anything Samana has to offer...
That is NOT to say that Samana is a bad destination in general...it does offer much...however, beaches is NOT one of its strengths...not that the Samana beaches are horrible... for example compared to some of the European 'beaches' (if you can call them such), Samana's are WAY ahead (some so-called 'beaches' in Europe don't even have SAND if you can believe it, and others have rocky 'sand'... no wonder the Europeans who have settled in Samana think Samana's beaches are great...yeah, great compared to what they are used)...The beaches I have mentioned are simply in another league...at least per the criteria normally used (having nearby mountains is NOT one such criterion, and neither is being remote or less visited by tourists).
