  • If swimming is suspended for short periods during stormy weather, we will transfer swimmers to and from booked slots and drop-in sessions to provide swimming opportunities to swimmers affected by the weather.
  • We do not offer refunds for lost swimming time, except for when we close the Bathing Pond entirely.
  • The Bathing Ponds are deep and the water opaque. They are suitable for competent swimmers only.
  • There are tethered life rings for swimmers to rest on, but swimming aids are not permitted in the Bathing Ponds.
  • The Bathing Ponds are natural bodies of untreated water with fluctuating levels of micro-organisms. High levels of micro-organisms can pose a risk to health and often occur after rain and when the ponds are heavily used. The risk of illness is greater for children, the elderly or immunocompromised people and some overseas visitors, as they can have lower immunity. The dangers include mild-gastroenteritis or eye, ear and respiratory infections. We recommend you consult a doctor if you have any health concerns, avoid swallowing pond water and shower before and after bathing.
  • Blue-green algae naturally occur in inland waters, estuaries and the sea. Blooms can form at various times of the year, most commonly in the summer months. We display notices at our Bathing Ponds when we detect signs of rising levels of blue-green algae. At times, we close our facilities due to the presence of blue-green algae.
  • Weekly water quality tests are undertaken by the Environment Agency between May-September and test results are available to view on the Environment Agency website.

We do not offer cold water induction sessions but strongly recommend winter swimmers read our cold water swimming guidelines.

  • Well behaved dogs may be tethered outside the facility while the owner swims. Dogs are left at the owner’s own risk.

    • These are dogs that have been formally trained to perform specific tasks for a disabled person. Assistance Dogs are individually trained by national or regional dog organisations.
    • Emotional Support Dogs and Therapy Dogs are not permitted at the Mixed Pond. These are dogs that provide comfort or emotional support to an individual but are not trained to perform specific tasks related to a disability.
