Le Canon

Le Canon sits in the arch cluster off Port-Louis's west coast, a quick boat ride from the harbour. The dive follows a vertical wall down to a sand plateau at around 20 metres, punctuated by an arch that gives the site its name. Large groupers hold territory around the arch itself, barracudas hang in the blue above the drop, and moray eels occupy the deeper crevices. Advanced Open Water or equivalent is the sensible level because of the depth and the occasional surge that runs along the wall when swells come in from the north. Best diving window runs from December through May.
