In the downtown area of Keynes, at dusk, along the waterfront avenue, about 10 minutes away, near the dock area, you will have a surprise. The huge Cairns Esplanade Swimming Lagoon is displayed in front of you. I can't believe my eyes at that time. The big naked swimming pool is displayed in front of you. I regret that I didn't bring my bathing suit with me. Swimming or playing is super good. The design of the whole lagoon is integrated into nature, and the integration is just right. It does not violate the feeling at all. At the same time, it does not show off too much, but it is really enough to showcase your eyes. Usually not open in the morning, noon can be used. There are many seabirds along the coast. They are dynamic. It's a paradise on earth to combine them. Keynes is a holiday resort, so there are not many people. Of course, if there are fewer people, it will be perfect. There's no need to worry about having nowhere to wash after the play, and there's a facility next to it, but in Keynes, it's normal to walk in a bathing suit.
