Products
Originally the valley had been used for the cultivation of sugar and a railway (since been lifted) was used to transport the sugar from further up the valley to a processing plant at Roseau. Until the 1980s there was a thriving farmer's and fisherman's market at Roseau, but since then most people now travel to the market at Castries. More recently, it was a major production area for bananas. As of 2022, the fertile valley is being developed due to the local banana industry being out-competed by international contenders.

The Saint Lucia Distillers, Limited was located in Roseau in 1972. It has produced several prize-winning rums since.
