Bosworth Water Park says customers will be expected to socially distance.
In a post to followers on social media, the owners said: "From Monday 1st June we will be opening to the public our grounds for recreational use."
The park has said that the office, cafe and hire equipment facilities and play areas will remained closed.
There will be toilet facilities open.
The park has stressed that customers will be required to socially distance on site at all times.
Like many leisure venues, the park was forced to close in March when the coronavirus lockdown started and since then has not been able to benefit from visitors during the good weather and bank holidays.
The park will re-open from 9am on Monday 1st June.
