There is a pool in the national landscape area called the Millingerwaard, that presents you with amazing reflections. When the river is high the pool fills up with clear water. When the river is low the pool disappears. Since the pool is embedded in the landscape, wind doesn't reach it easily and a mirror landscape appears through the vegetation and trees such as poplars and willows. You can walk around the pool in half a minute and every angle is a new experience, a world of amazing reflection.
