The two lakes here were dug out, not left by nature. Ballyhass sits in a disused limestone quarry that filled with spring water once the digging stopped, leaving 14 acres of clear, deep water ringed by the old cliff faces. The main lake runs to about 12 acres and roughly 11 metres down in places. That depth and clarity are the whole point: they make it possible to wakeboard, dive and float an inflatable obstacle course in the middle of north Cork farmland.
The centre opened in 1999 as a spring-water trout fishery and grew from there into a 36-acre activity site with more than 20 things to do on the water and around it.
Getting there
Ballyhass is signposted near the village of Cecilstown, about 15 minutes’ drive northwest of Mallow on the road towards Kanturk. Cork city is around 40 minutes away to the south. There’s parking on site. The quarry setting means the ground drops away in places, so keep an eye on children near the water’s edge away from the supervised zones.
On the water
The headline act is the Ballyhass Wakepark, run as Ireland’s largest wakeboarding cable park. Rather than being towed behind a boat, you’re pulled along by an overhead cable on a straight run; there are two systems and seven-plus obstacles to ride once you’ve found your feet. Every booking comes with one-to-one coaching, which matters, because standing up on a wakeboard for the first time is harder than it looks and the coaching is what stops the first session becoming a series of face-plants.
Kayaking and stand-up paddleboarding use the calmer lake, and there’s raft building for groups. The cliff faces left by the quarrying double as a natural climbing wall, and the deep, clear water also draws scuba divers and snorkellers looking for an inland training site.
The aqua park
In summer, a floating inflatable course is anchored out on the lake: a wipeout run of climbing walls, balance logs, trampolines and slides up to 3 metres. Up to 50 people can be on it at once, and it’s the thing most families come for. The minimum age is 6, and children between 6 and 11 need an adult in the water with them.
Everyone gets a wetsuit and a life jacket, and the safety briefing is thorough – reviewers with non-swimming children repeatedly note that the buoyancy aids make it manageable. Staff patrol the course on surfboards. One recurring gripe is worth flagging: the point where you climb out of the lake can be murky and awkward underfoot, even for adults.
The aqua park runs roughly May to September only, and it lives and dies by the weather. A grey, windy day on an exposed lake is a different proposition to a warm one, so check the forecast and book a good day rather than chancing it.
High ropes, dry land and fishing
Away from the water there are high and low ropes courses, zip lines that run out over the lake, and archery. Most of the land-based activities are built around groups of ten or more, which makes Ballyhass a common choice for school trips, corporate team-building days, and stag and hen parties as much as families.
The original fishery still operates. The main lake is fly fishing only for trout; the lower lake allows worm, spinning and bubble-and-fly methods. It’s a quiet counterpoint to the shrieking coming off the aqua park.
Prices, season and booking
At the time of writing an All Access Day Pass runs at about €35 per person, with early-bird tickets from around €30, and the day pass covers the aqua park, kayaking, archery and high nets between 11am and 5pm. A 12-month Adventure Pass, at roughly €49, gets you discounted rates across activities. In May, June and September the centre opens at weekends and on weekday afternoons; July and August it’s open seven days. The booking office number is 022 27773.
One thing to get right before you drive out: the water is spring-fed and stays cold even in a July heatwave. Bring a towel, dry clothes and something warm for afterwards, and if you’re doing the aqua park with young children, book the earliest slot on a settled, sunny day – the lake feels a lot friendlier at midday than it does at five in a rising wind. If the forecast is poor, Mallow Castle and the deer park at Doneraile Court make dry alternatives nearby.
