Kells Bay Gardens
Tucked into a sheltered valley on the Ring of Kerry, Kells Bay is Ireland's finest subtropical garden, where tree ferns, palms and bamboo flourish in the mild Atlantic air. Its trails wind down to Dingle Bay past a waterfall, wooden dinosaurs and the country's longest rope bridge, the swaying Sky Walk, strung high above a rushing mountain stream.
For a garden this exotic, the setting could hardly be more Irish: a steep, wooded valley funnelling down to the sea between Glenbeigh and Cahersiveen, where a Victorian hunting lodge sits among lawns and rhododendron. The magic is in the microclimate. Sheltered from frost and warmed by the Gulf Stream, this sliver of Kerry coast lets plants from the far southern hemisphere grow as if they were home, and over the years its owners - among them Billy Alexander, a multiple gold-medal winner at the RHS Chelsea Flower Show - have gathered one of the great collections of southern-hemisphere plants in Europe.
The centrepiece is the Primeval Forest, a dim, humid grove of tree ferns said to be the largest of its kind in the northern hemisphere. Many of the ferns are well over a century old, their trunks furred with moss, and walking among them under the dripping canopy feels genuinely prehistoric - an effect the gardeners lean into with a scatter of life-size wooden dinosaurs carved from storm-fallen trees, half-hidden along the paths for children to hunt down.

The other showstopper is the Sky Walk, promoted as Ireland's longest rope bridge, which sways some distance above a fast stream on the River Ramble trail. Beyond it, paths lead through a walled garden, past a waterfall and out along a cliff walk with long views over Dingle Bay. When you've had your fill of walking, there's a café by the entrance and, remarkably, an authentic Thai restaurant in the old lodge - a nod to the family's connections, and a genuinely good lunch stop.
Kells Bay lies just off the N70 between Glenbeigh and Cahersiveen, with free parking at the gate. Expect to spend one to two hours on the trails, which are steep and uneven in places, so decent shoes help. The gardens open through much of the year, from mid-morning, though hours, opening season and the small admission charge shift with the calendar, so it's worth checking before you set out. It sits neatly between Rossbeigh Beach and Cahersiveen, an easy and unexpected green detour on the Ring.
