Anse Chastenet has one of St. Lucia's most famous beaches. It's a fairly long stretch of dark sand with a marine preserve on one end near the dive shop. Great snorkeling on this beach and clear turquoise water. The sea is not as deep here as at Jalousie's beach, which is imported white sand if that makes a difference to you.

I don't know why you can't find enough images of the beach??? Just do a search in Google IMAGES titled:

"beach at anse chastenet st. lucia"

and you'll get more images than you know what to do with. Hope this helps!
