Summer Open Water Swim: Boundary (23/8)

About the Event

Summer Swims at Boundary Water Park, Cheshire, CW4 8HT invites swimmers of all levels to dive into its refreshing waters during sunny afternoons and leisurely mornings. Located within easy reach from the heart of Cheshire, this inviting venue offers a serene setting for both seasoned open water enthusiasts and newcomers alike.
Swimming sessions are scheduled on Sundays throughout May through August, running from 10:00 AM to 1:00 PM, providing ample time to enjoy the tranquil waters. Additionally, Thursday evenings offer an alternative schedule from 5:00 PM until 7:30 PM for those who prefer a cooler dip in the late afternoon sun. In September, Sundays continue with shorter sessions from 10:00 AM to 12:00 PM.
For members of Bronze and Squid tiers, there's an opportunity to secure your spot at a discounted rate by pre-booking through our website (www.uswimopenwater.com/boundary-water-park). This not only guarantees entry but also ensures you can enjoy the water without worrying about availability. Non-members are encouraged to register in advance as well; however, walk-ins will still be accommodated on a first-come, first-served basis with an additional fee applied.
Safety is paramount at Boundary Water Park. Swimmers must bring their own tow-float for buoyancy and visibility or can hire one directly from the venue if needed. With clear waters stretching out before you, it's easy to lose yourself in the rhythm of your strokes while taking in the beauty around you.
Last entry times are set 15 minutes prior to each session’s end, allowing ample time to warm up and prepare for a refreshing swim. Whether you’re looking to cool off on a hot summer day or simply enjoy the peaceful surroundings, Summer Swims at Boundary Water Park offers an ideal setting for all your aquatic adventures.
Join us this season for a memorable experience in Cheshire’s natural beauty.
