Dive Site Location & Key Facts
Dive Site Overview
Arches presents a distinct underwater experience in Greece, characterized by impressive natural rock formations. Divers encounter a varied topography featuring significant arches, accessible swim-through caverns, and dramatic reef walls.
The initial entry point typically leads to a shallower area, ideal for training and more relaxed explorations, starting around 7 meters. From this point, the site descends across a multilevel bottom, reaching maximum recreational depths of 40 m (131 ft). Certain sections of the extensive reef wall drop considerably deeper, extending beyond standard recreational limits for specialized divers.
For those with advanced certifications, a deep cave sits at approximately 30 m (100 ft), adorned with an array of vibrant sessile life including sponges and small corals. Navigating the deeper sections often leads back towards the main arch, providing an alternative perspective on its grandeur and scale.
This boat-accessible site is primarily a rocky dive spot, with minimal sandy bottom areas, focusing exploration on its dramatic geological features. Boat entry is the standard approach, facilitating direct access to the most compelling aspects of this intricate underwater landscape.

Dive Difficulty & Safety Guidelines
Approaching Arches requires mindful preparation, catering to a range of diver skill levels. The shallower sections are well-suited for Open Water divers, particularly around the initial entry points and within the naturally lit swim-through caverns. For exploring the deep cave or following the dramatic reef wall that extends beyond recreational limits, an Advanced Open Water certification is essential.
Divers considering these deeper explorations should also consider specific Deep Diver training. The site, accessible exclusively by boat, typically presents mild to no current, but carrying a Delayed Surface Marker Buoy (DSMB) is always a prudent piece of safety equipment.
A dive torch is advisable for illuminating the darker corners of the caverns and the deeper cave systems, ensuring full appreciation of the environment.
