How to have fun and stay safe in the water

Getting out and active on the water is a great way to enjoy and experience the National Park.  During the warm summer months, more and more people are taking to the water and for some people it may be the first time they have ever swam or paddled in open water.

But whether you are an experienced open water swimmer or just fancy dipping your toes in to cool off; it’s essential that you’re well prepared before getting in the water.

Water Wise

  • Never go into the water alone and always keep a close eye on friends and family, particularly young children. People can get into difficulty even in shallow water.
  • Even on a hot day the water is still very cold, Cold Water Shock can set in quickly and rapidly lead to hypothermia. Enter slowly so you have time to get used to it.
  • The water in lochs can change depth suddenly and unexpectedly, sometimes very close to shore with steep drops. It’s best to stick to places you already know or find out as much as you can about an area before you get in the water.
  • Always stay within your own capabilities and check the depth of the water bed by walking in carefully – if you can’t swim or are not an experienced swimmer then don’t paddle far from the shore as water depth can change suddenly and unexpectedly.
  • Stay sober – alcohol and water don’t mix well. Alcohol and drugs can have an impact on your swimming ability, body temperature and judgement.
  • Avoid jumping or diving straight into the water. As well as the shock of the cold water there is a risk of unseen hazards under the water.
  • If you do get into trouble in the water then float on your back and try not to panic. Follow the RNLI’s ‘Float to live’ advice:

  • Always take a few minutes to check on site for any signs warning you of dangers in that area and public rescue equipment (PRE).
  • Make sure you know where you are and have a note of your location in case you need to tell the emergency services.
  • To help you locate exactly where you are, the What3Words app generates a unique combination of three words to describe every 3 square metres across the world. Download the app and use it to provide you with a three word reference for where you are which can be passed to the emergency services to help them locate you quickly and easily (for example, Duncan Mills Slipway = galaxy.rooting.amphibian)
  • In an emergency call 999, ask for Police and provide the exact location of the emergency.

Swimming safely

  • Remember that the loch can be busy and although you may be able to see boaters, they may not be able to see you! Wear a bright swim cap and tow a bright float so you are more obvious to other loch users.
  • We strongly recommend you wear a wetsuit to keep you warmer and more buoyant.
  • Don’t swim alone – swim with at least one other person.
  • Avoid blue/green algae during the summer months.
  • When swimming in open water, there is a risk that you may develop a rash or itch known as Swimmer’s Itch (Cercarial Dermatitis). Find out more about this on our Swimming page.
  • Tell someone where you are going and when you expect to be back.
  • Check weather conditions before heading out and remember that conditions can change quickly – a large swell can quickly develop when wind directions change.
  • Some places are better than others for swimming. Make sure you familiarise yourself with the area before swimming or take part in any water based activity.
  • Be aware boaters may be in any area of the loch at any time of day or night. If possible avoid mooring areas, marinas and jetties used by boats, waterbus routes and boating channels. Know how to call for help – if you or someone you are with gets into difficulties while in any of the National Park’s bodies of water, call 999 and ask for the police.
  • On Loch Lomond we are very fortunate to have a volunteer operated rescue boat. Always know where you are so help can get to you as quickly as possible should you need it.
