Scuba diving at Sulphur Mines (Thiorichia / Paliorema) in Milos

Sulphur Mines (Thiorichia / Paliorema)

MilosBoat
About This Site
A uniquely atmospheric dive on the southeast coast of Milos, directly below the abandoned Thiorichia sulphur mine at Paliorema. The remains of the old loading pier mean the water drops away deep right off the colourful pebble beach, and divers follow the rocky reef and rubble slope beneath ghostly, orange- and yellow-stained industrial ruins. A recurring entry on "best dive sites of Milos" lists, it is prized for its eerie volcanic-industrial scenery rather than big marine encounters. Most divers reach it by boat as part of an east-coast or Kleftiko-area itinerary.

The site sits at the head of a narrow east-facing inlet on the far-eastern coast of Milos, its mouth opening ESE to the open Aegean, so the E-ESE-SE sectors are fully exposed to wind-wave and the long-fetch Scirocco. The bulk of Milos shelters the W, NW and SW sectors almost completely, while the neighbouring islands of Kimolos (to the N-NNE) and Polyaigos (to the NE) knock down the summer Meltemi, leaving only a moderate NE-ENE window where swell wraps past their western ends. Calmest in settled or N-NW-wind conditions; an E or SE blow quickly makes the open, "immediately deep" entry rough.
