This is an overlooked gem for outdoor swimming. The water looks murky, but it's safe to swim in and often exceeds the national guidelines. There's a lifeguard on hand, so it's a safe swimming experience. The water is very deep, so you must be a reasonably confident swimmer here, but there are floats you can grab hold of if you want to take a rest. This is the best place for birdwatching from the water. There's a resident kingfisher which I've seen on various occasions. I recommend optically corrected goggles if you normally wear glasses/contacts. The sky and trees look so beautiful from within the pond. Be prepared for a spartan changing area (with no lockers to stow valuables) and unheated showers. The water is cool, but they post the temperature so you don't ever have to experience something beyond your limit. I recommend year-round swimming, but to do this you need to acclimatise in the autumn so that you can handle temperatures mid-winter (0-6C). By the way, don't be intimidated by any imagined associations with cruising on the Heath, I've never experienced the slightest hint of cruising in the Men's pond. Most of us are just here to enjoy a good swim. read more
