Anse Chastanet is a reef bay 2 kilometres north of Soufrière, named for the estate that occupied the surrounding land and now home to the Anse Chastanet Resort, one of the longest-established boutique dive resorts in the eastern Caribbean. The bay is defined by two points of volcanic rock that frame a 200-metre crescent of dark sand — the colour coming from the volcanic mineral content in the Caribbean. The sand is grey-black rather than white, a characteristic of the volcanic beaches that occurs on several of the southern Windward Islands where basalt and andesite erosion feeds the beach rather than coral. The reef is the defining feature. The Anse Chastanet reef begins 10 metres from the beach waterline — no boat required — and descends in a series of wall sections to 40 metres depth on the outer face. At 10 metres the coral cover is dominated by star coral and brain coral heads, interspersed with sea fans and wire coral. At 20 metres the wall develops an overhang character, with black coral (antipatharian coral) on the undersides and large sea fans facing the current. Seahorses have been recorded in the rubble zone at 5 to 8 metres. The Caribbean tidal range at Anse Chastanet is 0.3 to 0.5 metres at springs — small enough that the entry depth from the beach changes by only a fraction of a metre across the tidal cycle, making shore diving timing-independent. The dive school and dive boat operation at Anse Chastanet is one of the most technically capable in Saint Lucia; the school carries PADI Gold Palm Resort status and runs courses from Open Water through Divemaster from the beach facility. The Trou au Diable cave system on the south side of the bay is accessible at low water — a partially submerged sea cave that requires swimming through an entrance at 2 metres depth. Snorkelling conditions from the beach are among the best in Saint Lucia: fish density in the shallower sections is high, visibility runs 15 to 25 metres in calm conditions, and the water is warm enough (26 to 28 degrees Celsius year-round) that a 3mm wetsuit is optional rather than required for most visitors. Hikers can reach Anse Chastanet from Soufrière by the coastal trail that runs along the cliff above the water, approximately 45 minutes on a clear path. The drive involves a steep unpaved descent from the estate gate; the resort provides shuttle transport from Soufrière for day visitors. The north side of the bay — Anse Mamin — is accessible by boat and is a quieter beach with a ruined sugar mill estate at the waterline, used by the resort for mountain biking on the estate trails. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. The Saint Lucia Meteorological Service and the Caribbean Meteorological Organization provide regional sea-state reference data.
