During the daytime life at Sandals St. Lucia seems to center around the large main pool. The waterfall above is part of this pool. At right is the main pool area and the pool bar in the middle. You can swim up or walk over a bridge on the other side. At left is the main bridge over the pool, which separates the main pool area from the smaller area with the waterfalls.
Some people sun, other people lie on the floats or lean on the floats.
One of my accomplishments at Sandals was to learn how to properly get on a float. I actually learned to do it better than that. If you drag the float toward you as you land on it, you can get your head on the pillow section. The beach didn't appear to be very popular. It is rather narrow, and after the first day, the waves were rather significant.
