For an amazing sunset you can take a little hike from the port of Gustavia, following the signs for Plage, and turn up the street behind Bagatelle. From there you have two choices but I recommend both.
1. Take the first right-hand turn and walk up the mosaic stairs at the end of the street to the hilltop where this photo was taken.
2. Take the second right-hand turn (sign for Plage) and curve around to Shell Beach and the fabulous Do Brazil Restaurant and Sunday clothes shop.
This is such an easily accessible beach with millions of shells, very "swimmable," great cocktails and optional topless tanning!
