Outdoor Pools and Rock Pools Perfect for Lap Swimming in Doncaster

Lap swimmers looking to stay cool and active have plenty to celebrate this summer: Doncaster’s outdoor pools and hidden rock pools are open for daily sessions, drawing a steady stream of fitness fans from across South Yorkshire.

This renewed interest in outdoor swimming is no accident. Health guidelines have recently highlighted the benefits of exercising outside, both for muscle strength and mental wellbeing, while public campaigns across Doncaster have urged residents to reclaim the city’s blue spaces after years when most swimming happened indoors. With the school holidays approaching, families and solo swimmers alike are seeking healthy ways to enjoy the sunshine close to home.

Where to Swim Laps in the Open Air

Doncaster’s best-known outdoor pool remains Sandall Park Lido on Thorne Road, where the 25-metre pool has welcomed swimmers since the 1930s. The lido was recently refurbished by Friends of Sandall Park, and lap swimming sessions are now held every weekday morning from 7am, catering specifically to those looking for a serious workout. Early risers frequent the scene, many cycling in from Wheatley Hills or Intake before work.

If you’re after a wilder experience, Sprotbrough Rock Pool is Doncaster’s worst-kept secret. Tucked behind the Don Gorge and accessed via Boat Lane, the spring-fed rock pool is naturally cool all summer long. Local group Doncaster Open Water Swimmers organises group swims on Saturdays, and lap swimmers note the current is steady enough for a powerful training session, though the uneven pool floor may take some getting used to.

Both Sandall Park and Sprotbrough have seen a marked uptick in visitors. According to City of Doncaster Council data from 2025, Sandall Park Lido reported over 9,000 lap swim entries between May and September last year, a 22% increase on pre-pandemic numbers. Entry to the lido costs £5 per adult session, while membership in Doncaster Open Water Swimmers opens access to Sprotbrough Rock Pool for £15 a month. The council is trialling an online booking system this season to help manage demand and improve safety through capped session sizes.

Getting Ready for a Swim

Those interested in outdoor lap swimming should check the opening hours before heading out, and bring a brightly coloured swim cap for visibility. For Sandall Park Lido, wetsuits are optional but goggles are a must for lap swimmers. Safety signage at Sprotbrough Rock Pool recommends never swimming alone due to the depth and variable currents. With more heatwaves forecast and many residents seeking low-cost fitness activities, Doncaster’s outdoor pools look set for their busiest summer yet.
