RIVIÈRE DES ANGUILLES (Eel River) is a service town for one of Mauritius’s largest sugar plantations. Most people pass through on a visit to La Vanille Réserve des Mascareignes, a popular family attraction, but the colourful South-Indian Tamil Tookay Temple, sited atmospherically in the sugar fields near Camp Diable, is worthy of a diversion. A more adventurous side-trip is to the small Le Souffleur blowhole, on the Savanna Sugar Estate near the village of L’Escalier. The water here once spurted out up to 18m, but since the hole has eroded, it’s more like 6m these days. It’s a bit tricky to get to along rough tracks, so best visited by 4WD and the help of a local. About 2km east along the coastal path is the perhaps more impressive Pont Naturel, a natural rock bridge over the boiling sea.
