Excellent place to stay at especially since they have it separated into families or adults-only sections. The beach is well maintained with plenty of beach sports options.

Great Stay
The resort is small but lovely. The main restaurant had great food. The accommodations were great and it was nice to have kayaking and paddle boarding included. The only downside which the resort can’t do anything about was that the low tide starts around 430pm. Then you have to head for the pool!
