About Mourtias Reef
Mourtias Reef is an Alonissos marine-park reef-and-wall dive with a shallow reef top, a bigger wall edge, and a calm operator-led rhythm. The route changes with weather, but the site’s best version is a slow, buoyancy-conscious reef dive with sea grass on the return and plenty of small-life detail along the wall and top of the stone reef.

Local Intel For Mourtias Reef
Community notes to help plan your visit.
Scuba Diving
A good fit for relaxed recreational scuba and buoyancy practice. Open Water divers can usually enjoy it when conditions are calm and the operator is selecting the easier side.
Freediving
Possible only as a conservative calm-day option and only with operator approval; the wall profile makes scuba the primary use case.
Snorkeling
Snorkeling may be fine in the shallow bay edge on very calm days, but the site is mainly planned as a scuba dive.
