St Andrews Lakes is a spring-fed freshwater lake complex situated in a reclaimed former chalk quarry near Rochester. The site features a significant body of crystal-clear water utilized for a variety of open-water activities including scuba diving, paddleboarding, and open-water swimming. The facility includes a dedicated artificial beach area for swimming and relaxation. A marked underwater training platform exists for certified scuba divers and students. The surrounding terrain consists of steep cliff edges and natural vegetation typical of the North Downs landscape. Several floating obstacle courses and inflatable platforms are installed on the water for recreational use. On-site facilities include changing rooms and a cafe overlooking the lake. The site remains popular for both water sports training and casual family recreation throughout the warmer months.
The elevated viewing area near the main entrance provides a panoramic vista of the entire lake and the stark white quarry cliffs.
Book water activity slots in advance, as capacity for swimming and paddleboarding is strictly managed.
Bring water shoes, as the lake bed transition from the beach to deep water can be pebbly.
Pack a wetsuit if you plan to swim outside of the peak summer heat, as spring-fed waters remain cool.
Do not attempt to swim in areas outside the designated beach and supervised zones, as the quarry edges are deep and steep.
The site operates seasonally; most water-based activities close during the winter months.
Swimmers must wear a brightly colored tow-float for safety; all water sports participants must sign an activity waiver prior to entering the water.
