The Eden Rock Hotel is a great place to enjoy sunsets with your loved ones. It is the glitziest hotel in St. Barths, but you can have a lovely drink at the bar aptly called On the Rock for an (almost) reasonable price.
When dark sets in, the hotel turns on a powerful light projector that lets you see over the nearby surf.
The atmosphere is casual chic, with an emphasis on chic.
You can also eat there, but it is pricey (and worth it). The menu has been created by famous chef Jean-Georges.
Advice: Book a table, dress up, and do arrive before sunset.
Trivia: Eden Rock is also the very first hotel that opened its doors in Saint Barthélemy decades ago. Today, it belongs to the Matthews family, a very successful British entrepreneurial family.
