Swim at Ballyhass
Open Water Swim
A genuine open water session for established swimmers who want distance, rhythm and a proper freshwater training environment at Ballyhass Mallow. This is not the relaxed leisure swim route. It is built for confident swimmers comfortable covering 500m or more.
450m to 500m Loop Distance Swimming Only Adventure Pass Savings
Open Water Swim is structured training with its own schedule and season. For relaxed, recreational swimming in the designated, enclosed swimming area, including selected lifeguarded dates in winter, see Lake Swim. Open water dates and times can change through the season. Check the live booking page for the current running schedule before travelling.
Who it is for
