St Lucia Beach for October

If you want to mingle with the locals, spend the day at Soufriere Bay. Located within Soufriere, this golden sand beach is lined by tropical rainforest on one side which provides some much-needed natural shade and calm waters on the other side which are the ideal temperature for swimming. There are sun loungers and parasols on the beach but you can't rent them if you want to use them, all you need to do is buy something from the beach bar and you'll have unlimited access to them. The clear water is ideal for snorkelling, although you won't see many tropical fish or coral formations on this part of the island. Because of this, this beach isn't popular with tourists and is mainly frequented by local families.

For a quiet, unspoilt beach in St Lucia, head to Roseau Bay. Located within Marigot Bay, this beach offers no facilities of any sort, so you'll need to bring your own food and drinks or take advantage of the cafes, bars and restaurants a short walk away in the resort. This secluded sandy beach is lined by palm trees which develop into forest-clad mountain faces, providing a stunning backdrop. The warm, calm waters are perfect for swimming and thanks to their clear and shallow characteristics, they're also great for snorkelling. Be aware that there are no toilets, so families with very young children might be better off spending the day elsewhere.
