Nai Wong Ranong is a GI name for Monthong grown in the Nai Wong valley of La-Un district, Ranong, on Thailand's Andaman coast. The trees were grafted from Chumphon stock and planted from the 1990s. High rainfall and the mountain-ringed valley are credited with a firm, almost crisp flesh and a milder smell than typical Monthong. The GI covers only the two Nai Wong sub-districts, so Monthong from elsewhere in Ranong does not qualify. It ripens late and is mostly sold in the south.
