Lots of water sports to do there prices are negotiable. We went tubbing for $8 per person(they wanted $10).
About 15-20 minutes from the Castries (cruise ship port) cost $25 each way for group of 4 people.
Beach chairs and unbrellas are available for about $15 (2 people).
Full service bar with bathrooms was close.
Very calm surf, very clear water.
Would have preferred to visit the Pitons, but it was expensive ($140 one way for 4 people) and took 1H 30M to get there from Castries.
Downside was way too many vendors!
Had a great time there.
