Swanage outdoor company owners buy Dorset Adventure Park

The inflatable waterpark and mud trail at Corfe Castle in Dorset has been sold to the directors of the Swanage-based company Cumulus Outdoors.

Dorset Adventure Park, set within 18 acres of woodland and lakes, was founded by Liz and Robert Mulliner in 2016 as a waterpark, with a two kilometre mud trail created two years later in 2018.

Since then, the leisure attraction has become an established and popular place for schools, families and holidaymakers to visit.

Cumulus Outdoors is a school residential and activity specialist delivering school trips and activity days, Duke of Edinburgh gold residentials and walking expeditions.

Its directors take over ownership from November 2024, with the Dorset Adventure Company operating as a sister company.

Strategic move

Over the years, Cumulus has become one of the adventure park’s biggest customers, with its bespoke school and youth group residential programmes including the exciting water and mud trail activities.

The company’s directors Tom Campbell-Hill and Sam Thompson say the purchase is a strategic move, which will secure the facilities for its clientele, as well as promote the company’s mission to inspire optimism and happiness in young people through outdoor learning and experiences.

They hope that the collaboration between these sister companies will enable further development of the range of activities available to young people, their families and other groups.

Cumulus Outdoors director Tom Campbell-Hill, said:

“We are delighted to have had the opportunity to acquire Dorset Adventure Park.

“We are excited by the range of opportunities this acquisition will provide to our school and youth groups, as well as visitors to our wonderful region and the local community.”

Tom and his fellow director Sam, say they are dedicated to a smooth integration process for Dorset Adventure Park and its workforce and that customers of Dorset Adventure Park should expect to enjoy the same exceptional service and experiences, now supported by Cumulus Outdoors.

Success story

Originally, the waterpark was the idea of Liz Mulliner, who along with her husband Rob, founded the attraction.

Having been on holiday in Tenerife and seen people enjoying the inflatables, Liz wondered if the concept would be just as popular in the cooler Dorset climate. Fortunately it turned out that they are just as enthusiastic to get wet and muddy, even if it is raining!

The couple weathered the storm of the Covid pandemic in 2020, when the attraction wasn’t able to open at all. However when people were freed from lockdown in 2021, the park had its busiest year as everyone was holidaying in the UK and keen to get outdoors.

Now Liz and Rob are able to move on to another adventure, confident that their success story will be continued.
