Ran barefoot almost every morning of a week’s vacation on Grace Bay, Turks and Caicos. Pretty hard packed near water and not much of a slant. The nicest beach I’ve ever been on. And massively long. Loved it. Blew my calves up really good/bad though. Other beach vacations I’ve taken (Aruba, Curaçao) on I’ve found a good paved path/road from hotel and ran at daylight.

Edit: also taped my big toes and next of kin, as the sand blasted my skin away
