Either Chung Kneas or Mechrey village, both offer fantastic sightseeing when the boat cruising pass floating communities where you can see a lot of fishing activities come to local life. By overland before reaching one of these villages, Mechrey is more suitable because the journey goes passing beautiful rice paddies which is considered as the best landscape of all.
