So all the beaches on the north shore are beautiful ... this one is too. This one though you have to hike to, about 20 minutes, some parts of the trail are rocky and you have to be sure footed. This is good because it keeps a lot of people away.
Snorkeling is OK. Maho or Trunk are better.
Bring real shoes to walk, and everything you will need. There is nothing here...no services, no bathrooms..nothing but sand and water.
