Planned Diving

Advice for swimmers

There are any many options for swimming. Stay reasonably close to the shore, test the depth. Even good swimmers need to be in reasonably shallow water where you can quickly put your feet down. This may seem over cautious but even strong swimmers may get into trouble. Choose your location for swimming carefully, consider wearing a wetsuit, high visibility cap and tow a float.
