Complete guide to swimming at Hampstead Heath ponds: opening times, water temperature, entry fees, the difference between the three ponds, and everything first-timers need to know.
Hampstead Heath Swimming: Everything You Need to Know About the Ponds
Hampstead Heath's bathing ponds are among the most distinctive swimming facilities in Britain: natural ponds, unheated, set within the 790 acres of the Heath, open year-round (the single-sex ponds) or from April to September (the mixed pond). They have been in use as bathing places for over 300 years and have a character that no municipal swimming pool replicates. This guide covers everything a first-time visitor needs to know.
Key Takeaways
- There are three ponds: Men's, Ladies', and Mixed, each with distinct character and community
- The Men's and Ladies' ponds are open year-round from 7am; the Mixed pond opens April to late September
- Water temperature: 4-6°C in January-February; 20-22°C at summer peak
- Entry fee: approximately £2 per swim (check current prices); annual memberships available
- The Ladies' pond has the strongest swimmer community and is often cited as the most atmospheric
The Three Ponds
The Ladies' Pond
The Ladies' Pond (formally the Kenwood Ladies' Bathing Pond) is, by many accounts, the most characterful of the three. The pond is surrounded by mature willow trees that screen it from the surrounding Heath, creating an enclosed, self-contained atmosphere. The water is consistently clear; the wildlife, including a resident population of grebes, herons, and Muscovy ducks, is abundant and accustomed to swimmers.
The Ladies' Pond has a strong year-round swimming community; the winter swimming cohort here is the most active of any of the three ponds. The changing facilities are basic but functional.
Open: Year-round from 7am (summer extended hours from late May).
The Men's Pond
The Men's Pond (Millfield Lane) is the oldest of the three ponds in terms of swimming tradition and home to the Hampstead Heath Winter Swimming Club, founded in 1902. The Peter Pan Cup Christmas morning race has been run here since 1904.
The pond is slightly larger than the Ladies' pond with a different swimming approach: the main swimming area is marked with a rope; the water entry point has steps rather than a diving platform.
Open: Year-round from 7am.
The Mixed Pond
The Mixed Bathing Pond is the most conventionally popular, the one that most visitors try first, the one that fills on summer weekends, the one with the queues on hot June Saturdays. It opens seasonally (April to late September) and closes in winter.
The mixed pond has a diving platform and the longest season of the three options for less committed open-water swimmers. On a warm summer morning, it provides one of the finest swimming experiences in Zone 2.
Open: April to late September, from 7am (summer) or later in shoulder months.

Entry and Fees
Entry to all three ponds is charged. Current prices (verify on the City of London website before visiting): - Adults: approximately £2 per swim - Concessions (over 60, students, unemployed, disabled): reduced rate - Children under 15: reduced rate - Annual memberships: available and economical for regular swimmers
Payment is by card at the gate. Cash is not always accepted, check before arriving.
What to bring: - Towel and changing robe (the changing facilities are basic; a changing robe simplifies the transition) - Secure footwear, the path from the changing area to the water is often muddy - Ear plugs if you are prone to swimmer's ear (the pond water is clean but natural) - After-swim warm clothing, essential in autumn and winter
What not to bring: - Goggles are optional but useful for open-water swimming - Swimwear covers the expected range; no specific requirements beyond basic modesty - Waterproof phone case if you want to photograph from the water
Entry procedure: Queue at the entrance gate, pay the fee, proceed to changing area, swim, return to changing area, exit. Simple and self-explanatory.
Wildlife caution: The ponds contain ducks, geese, and coots that are accustomed to swimmers and not shy. Avoid feeding them; they will crowd you if fed.
The Open-Water Swimming Season
Summer (June-August): The busiest period. Arrive before 8am on weekends to avoid the main queue. Water at its warmest; the swimming experience is closest to a conventional outdoor pool.
Spring (April-May): The water is cold (8-15°C) but the crowds are thin. This is when the experienced open-water swimmers who dislike summer crowds have the ponds relatively to themselves.
Autumn (September-October): The water retains summer warmth into September; October cools rapidly. The pond atmosphere in early October, leaves beginning to turn, fewer swimmers, is one of the better seasonal experiences the Heath offers.
Winter (November-March): Men's and Ladies' ponds only (Mixed closes). Water at 4-8°C. The winter swimming community; the Peter Pan Cup in December; the specific rewards of cold water immersion. See our winter swimming guide for more.
Conclusion
Swimming at Hampstead Heath ponds is the kind of experience that sounds interesting in description and becomes essential in practice. The combination of natural water, open air, and the particular atmosphere of the Heath makes it unlike any municipal swimming facility.
Go in summer for the warmth and the social atmosphere. Go in autumn for the transition. Go in winter, if you're willing, for the reward on the other side of the cold.
