Muddy beach is generally found near the mouths of all rivers meeting the sea. Its outstanding character is a big muddy plain extending the sea. The soil is rich of nutrients washed down by the river. To observe the rich ecology system and the local fishery by boat is both informative and joyful.

To enjoy the muddy-beach trip needs a little prior planning. The most suitable time is during the highest/lowest tide between the 13th waxing and waning moons and the 1th  waxing and waning moons (about 4-5 days of each round). The locals call this time Wan Nam Koet meaning the fast current days of the month (in opposite of Nam Tai meaning rather stagnant water). Coastal fishery is active when the water is last following, as seine, fish trap and dip nets need current to bring in the fish. Also, activities at the Blooded Cockle’s farms are better seen during low tide.
