Thursday evening swimming and diving will end on Thursday 12th September.

We welcome open water swimmers between 9am and 1pm on any Saturday, Sunday or Bank Holiday Mondays, and on Thursday evenings between 5:30pm and 8pm or 30 mins before sunset, which ever is earlier between mid-May and mid-September.

The site is open for swimming at all times of the year but it should be noted that the temperatures can drop rapidly to approximately 4–5 degrees Celsius during December and do not start to rise appreciably until the end of April.

All swimmers shall at all times wear suitable thermal protection or if swimming without a wet suit then they shall use a tow float.

Swimmers will be asked to read a copy of the site rules and will be asked to sign a disclaimer indicating that they understand the rules and restrictions of the diving centre on arrival.

Swimming is strictly limited to the marked course.

Want to swim at Cromhall?

Other swimming events, triathlon training, etc.

The quarry plays regular host to many sporting challenges and activities throughout the year.

Due to the good water quality in the summer months Wednesday and Thursday evenings are mostly busy with Triathlon events organised by K2 Sports, including the South Glos Evening Triathlon Series 2016.

The South West Seals are a bunch of crazy cold water swimmers (they swim in just swimsuits between October and February) who raise money for charity through their swims.  Cromhall has become their regular place to meet and train.
