Please note that these sessions must be pre-booked [details below] to enable to us to manage the number of swimmers with us at any time

We have also been able to open up another part of the lake, Lockdown Lake, to allow additional swim sessions to try and accommodate as many of you as we can.

Spaces can be purchased here and will be sold on a first come first serve basis – please note ‘walk-ups’ [i.e. if you have not booked] will be refused entry. Please read and acknowledge the waiver form to save time/ contact when you arrive at the lake.

We are aware that not everyone will get a space due to the limited numbers initially available however we are looking to add additional times/ dates as demand requires.

We have updated our swimmer guidelines as follows:

  • Pre-paid bookings only – booking of consecutive slots on same day is not allowed.

  • Price per swim has been temporarily increased to £8 to cover our costs which have remained the same – we hope you understand and this will be reviewed and amended as we get back to normal.

  • Entry to lake using usual pathway.

  • Booking checked upon arrival.

  • Swimmers expected to arrive lakeside at their pre-booked time changed and ready to swim [changing rooms will not be available and staff are not able to assist with zipping up wetsuits]. There will be a designated area for you to leave a bag/ dry-robe etc.

  • Entry will be via usual jetty – social distancing to be respected by all swimmers whenever required.

  • ‘Faffing’ [acclimatisation] upon entry is allowed, on the condition you move away from the entry point so as not to delay other swimmers from entering the water.

  • Exit will be via separate ‘Swim Out’ point – this will be shown to you when you arrive. You may be reminded by kayakers when your allocated time is nearing an end.

  • Upon finishing your swim, please collect your bag and leave via separate exit route [sign-posted].

  • No changing allowed at lakeside.
