Anse Marron is a stunning beach on the south west coast, but it is only for the intrepid. Whether you aim to come from Anse Source D'Argent on the west coast or Grand Anse in the south, the route is unmarked and treacherous, involving clambering over boulders, squeezing through narrow gaps between rocks and wading through water - it would be foolish to attempt it without a guide.
For those who come with sensible footwear, a local guide and plenty of energy, it is a very rewarding beach - but if you lack any of those three, you're best off sticking to somewhere more accessible!
