The Seychelles is regarded as one of the most romantic destinations on earth, and rightly so.

(One resort on this list even has a beachfront proposal spot that has long been a favorite for locals.) Our hotel investigators explored the Indian Ocean archipelago to find the resorts offering the most privacy, the best service, and the most splendid settings.
