Country and leisure parks operator, Park Leisure, has acquired the Plas Coch Holiday Home Park in Anglesey for £15m from the McAllister family.
Colliers International, adviser on the deal, said it was the largest holiday park transaction in Wales for four years.
Situated on the Isle of Anglesey, Plas Coch, which means Red Mansion in Welsh, is located close to the shallow tidal waters of the Menai Strait.
The 320-pitch holiday park in 60 acres provides static caravans, cabins and lodges in a range of sizes, available to buy and to let.
Plas Coch is the eleventh asset in the Park Leisure Group and is the group's first holiday home park acquisition in Wales.
Grant Gidman, head of marketing at Park Leisure, said: "Plas Coch is truly stunning and ideally represents the evolution of our 5-star vision for our parks. By welcoming the UK's most sought after holiday park to the group, we believe we will be inspired to continue to push the boundaries of excellence for our owners."
Richard Moss, director of parks, sports and marinas at Colliers, who represented Park Leisure, added: "I advised Park Leisure on the acquisition of their first park 17 years ago and it's inspiring to see how the brand has evolved and expanded over that time. With parks across the North and another in Cornwall, Park Leisure's latest acquisition of this prestigious 5-star holiday park in North Wales cements the group's transition from a regional business to a national operator."
