With over 200 kilometres of diverse coastline to explore, Northern Ireland is packed with incredible places for wild swimming, sea swimming and open water adventures.

The popularity of wild swimming and sea swimming continues to grow, with links being drawn to the long-term benefits of cold-water immersion. These include better sleep, helping to lower and manage stress and anxiety levels, and reducing blood pressure.

If you are considering taking to the open water, either for exercise or the cold water benefits, we strongly recommend doing your own research in advance, and especially if this will be your first swim, be vigilant of your limits and your ability level. One common top tip is not to attempt to jump straight in to cold water; if you are not acclimatised, the low temperature of the water can astound you and lead to shock. Instead, pace yourself, walk/dip yourself in slowly and control your breathing. This is an activity where a little preparation makes all the difference.
