you'll find SXM is way more "americanized" (or europeanated?) than BVI...not necessarily a bad thing, but you won't find a lot of the true caribbean island vibe you'd find on other islands...years ago Kali's Beach Bar in Friar's Bay had a decent vibe, and even had full-moon parties, but although the bar is still there, i think it's lost it's charm and hasn't had regular full-moon parties in many years...i can't think of any place now that would be like Quito's in CGB (at least how i remember it), and nothing like the old Bomba's.

On Anguilla, i think Sandy Ground or Bankie's Dune Preserve would be worth checking out, usually a quick 20 minute ferry ride from Marigot, but due to Covid, unless things have changed, probably a hassle to visit currently
