While visitors can swim anywhere in the ocean, the National Park Service provides a lifeguarded beach for those wishing to use it.

Lifeguards have not been provided since 2008; visitors swim at their own risk.

Next year the park will open Discovery Cove, an area where visitors can swim with dolphins and snorkel among stingrays.

Along the shore, two and a half miles of golden sands slip slowly into a warm, blue sea where visitors can swim, sail and wind-surf.
