In the north eastern corner of Poland lies a treat for nature and water lovers: thousands of post-glacial lakes and 200km of interconnecting canals that you could spend weeks exploring. Our kayak trip was glorious: the water was so still it felt as though we were paddling through the sky. Paddling here will take you through evergreen lined canals, past marinas packed full of yachts and into peaceful little bays perfect for a picnic stop.
