Looking for an outdoor swim in London in 2026? Choose a managed lake, designated bathing pond or lido and check the operator’s live timetable before travelling. Seasonal venues can close for weather, water quality or maintenance. Swimming in rivers, park lakes or the Royal Docks outside authorised sessions is unsafe and may be prohibited.
Beckenham Place Park Lake
Lewisham’s purpose-built swimming lake offers managed open-water sessions in Beckenham Place Park. Availability, age rules and booking arrangements vary by season, so check Lewisham Council’s lake information before setting off.
Hampstead Heath bathing ponds and Parliament Hill Lido
Hampstead Heath has the Kenwood Ladies’, Highgate Men’s and Mixed Bathing Ponds, as well as Parliament Hill Lido. The City of London publishes current pond and lido information. Some sessions require advance booking and the Mixed Pond runs seasonally; check the individual venue’s rules, timetable and eligibility.
The Serpentine Lido, Hyde Park
The designated public swimming area is the Serpentine Lido. The Royal Parks says public swimming usually runs on weekends from mid-May and daily from June to mid-September; the Lido is closed for winter as of late September 2026. Check the current season, booking and water-quality updates before a visit. Do not swim elsewhere in the lake.
London Fields Lido
If you prefer a heated outdoor pool, London Fields Lido is a useful year-round option. Check the operator’s live timetable for public-swim slots, prices and any maintenance closures.
Royal Docks supervised swimming
The Royal Docks are working waters and are not open for general swimming. Join only an authorised, supervised session with a licensed operator. The Royal Docks’ 2026 safety advice explains why open entry to the water is not permitted.
Planning your swim
Bring suitable swimwear, check age and supervision rules and follow the venue’s safety instructions. Fees and opening hours change, so we link to operators instead of quoting old prices. For more time in the city, see our five-day itinerary, where to stay guide and London attractions.
