At the northern end between mangrove swamps is the 28 km² ''Thale Noi'' in Phatthalung Province. The most striking feature is the long 75 km long spit which separates the lake from the sea. Unlike most spits, it was probably formed when originally existing islands were connected by silting from the lake precursor.
