Tongwell Lake seems to be Milton Keynes’ very own swan haven. The path around the lake is easy to follow as it only takes around 30 minutes to walk the whole way round. At times it’s not possible to see the lake through the reeds and bushes but in the openings you can enjoy some nice views of nature. There’s a large island in the middle of the lake, so if you’re a birdwatcher we recommend bringing some binoculars to spot any birds over there.
