Just 9km of Bruges, Damme is a small town which is much quieter and relaxing than Bruges, with fewer tourists which is why I recommend it. iI the weather helps, you can go biking because there's a delightful path by the side of a canal, with meadows and mills. On the way back you can retrace your steps or, if you don't want to pedal anymore, you can get on a boat where you can take the bike and return to Bruges.
Like every summer we choose somewhere to go and pack the car with our tent and then set off to discover new places. This year it was Belgium-Netherlands, among many other sites include Damme, for its tranquility and beauty of its surroundings.
