Our Lake & On-Site Facilities

The lake is a 270m circuit from the beach area down to and around the bouy then back around the Aquapark equipment swimming in an anticlockwise direction.

3 Meters Deep + 2 Circuits

The lake is 3m deep and we have two circuits available of either 270m or 75m when the Aquapark is not in use. We are accredited by both the British triathlon association. In addition we have R.L.S.S. qualified lifeguards on duty for your safety who receive our in-house ongoing training from our qualified open water Lifeguard trainer assessor! 

On-site changing, shower and toilet facility available.

The water temperature obviously fluctuates depending on the weather. However, the lake retains and maintains its temperature very well according to our triathlete members who visit many different venues! 

Additional Open Water Swimming Features…

Adjacent to the swimming lake is the the stylish Badgers barn Bar Restaurant or, alternatively, there is an excellent Costa coffee shop within the leisure complex! There is also a late night show bar.

Other on-site facilities include 9 hole golf course, various fishing lakes, multi sports court, an adventure playground complete with a zip wire and the one and only Lincolnshire Aquapark! All of which are open to the public, who are always truly blown away when viewing the quality of the on-site facilities.

You will find us at the fabulous Grange leisure park complex (LN12 1NE) on the outskirts of Mablethorpe where a superb watersports lake and open water swimming venue has been created and tailored accordingly for this specific use! 

A selection of Wetsuit hire options are available and we encourage everyone interested to come and view our facility at any time to discuss the simple induction process. After you’ve had your induction, you can just turn up at one of our sessions and take part.
