The park, which has 10 obstacles, will open from 10am on Saturday for members of the public to use.
The water park, which will be situated at Paxton Lakes, will be open seven days a week between 10am and 8pm during the summer holidays.
Owner of the park, Southlake ran a similar facility in Oxford previously, but will move it to St Neots.
Director Martin Beaver said: “With over 30 years of experience within the leisure industry, our aim is to continue to provide a fun, safe and happy environment for all visitors.
“It’s great fun for the kids and also families too. Adults turn up and as soon as they get on the park they feel seven years old again.
“At our previous location we saw families making a regular trip. People turned up a second of third time because they enjoyed themselves so much.”
Prices will be £15 each for a 50-minute session on the inflatable, with wet suits available to hire on site for £5 each.
