Piton Hyacinthe, Mountain peak in Plaine des Cafres, Reunion Island.

Piton Hyacinthe is a mountain peak in the Plaine des Cafres on Reunion Island, rising to an elevation of 1,372 meters. The slopes are covered with geraniums and acacia trees growing among cultivated agricultural fields.

The peak is named after Hyacinthe de Kerguelen de Kerbiquet, a Capuchin priest on Bourbon island around 1689. The sources record only this namesake and date; they attribute no further role in colonial events to him.

The peak takes its name from Hyacinthe de Kerguelen de Kerbiquet, a Capuchin priest on Bourbon island around 1689. The hamlet of Piton Hyacinthe below the summit carries the same name, so the toponym recalls a missionary rather than a crop or a landowner.

The summit lies on the territory of Le Tampon, between the hamlets of Piton Hyacinthe to the southwest, Bois Court to the north and the Plaine des Cafres to the east. The peak rises to 1,372 m at the foot of the Plaine des Cafres, about 7.6 km from Le Tampon and 40 km from Saint-Denis. Access is by road from Le Tampon; the slopes are farmland, so stay on tracks.

The red-and-white lattice mast on the summit is a telecommunications relay, not a television transmitter: no source records digital broadcasting from this peak. The peak itself, at 1,372 m, is named after Hyacinthe de Kerguelen de Kerbiquet, a Capuchin on Bourbon around 1689, and rises between the hamlets of Piton Hyacinthe, Bois Court and the Plaine des Cafres.
