What is good to know if travelling to Saint Lucia?

  • Don’t miss the drive-in volcano, Mount Soufriere. It is said to be the only drive-in volcano in the world.
  • Pigeon Island is a national park on a 40-acre islet linked by a causeway to the west coast of St Lucia. It has several military sites (barracks and garrisons) built by the British as they fought the French for control of St Lucia.
  • Bathe like a French soldier: when the French “owned” St Lucia, King Louis XVI had bathhouses built for his men at Diamond Falls. The mineral-rich falls were believed to have therapeutic properties. A dip under the falls is still popular. And the ever-changing colours – the water turns yellow, then black then green then grey – come from sulphuric deposits over many years.
  • The Pitons can be climbed in about two hours. Bathe in the nearby Sulphur Springs, a mineral-rich river. Afterwards, have a local beer of the same name.
  • La Tille waterfall, set in a ten-acre natural garden, is less well-known than Diamond Falls, but beautiful.
  • Leatherback turtles crawl onto the beach at Grande Anse in the north of the island to lay their eggs, between mid-March and the end of July.
  • Take a hike through the rainforest. The Barre de l’lsle Trail splits the island in two and takes about three hours to hike.
