Gianniskari Cave is a marine cave dive located in Crete, offering an enclosed underwater environment at a fixed depth of 19 metres. The site is accessible via both shore and boat entries. Visibility at the cave ranges from 10 to 30 metres, and the lack of current makes it suitable for Open Water certified divers. As an overhead environment, divers must exercise caution and remain within the cave entrance where natural light is visible unless they possess specific cave diving training. Carrying a torch is recommended for visibility and buddy communication. Conditions vary, so planning for a calm, sunny morning is advised for optimal light penetration.

Falasarna Beach in Crete provides a versatile site for both diving and snorkelling, featuring a combination of reef and wreck topography. The site is suitable for beginners, with depths ranging from 2 to 10 metres and an average of 6 metres. Visibility is generally good, spanning 10 to 30 metres. Entry can be made from either the shore or a boat. Divers and snorkellers should be aware of variable currents and the presence of sea urchins in the shallows. Facilities including parking, toilets, and showers are available. A wetsuit is recommended to manage water temperatures, which fluctuate between 16°C and 26°C throughout the year.

Gianniskari Reef is a deep-water site located 700 metres offshore, requiring boat access. The reef structure descends from 25 to 42 metres, offering consistent visibility of 30 metres. Due to the significant depth and strong currents, this site is suited for intermediate divers. Divers must monitor gas consumption and no-decompression limits closely throughout the typical 23-minute dive. Because currents can shift based on season and tide, it is essential to coordinate with your dive operator and plan your descent and ascent carefully. Staying near the ascent line is recommended given the boat-only access and the potential for currents to push divers away from the reef.

Paleochora Schisto Lighthouse is a boat-access site off Crete offering a diverse underwater landscape of reef, wall, cave, and artificial reef structures. The site reaches depths between 18 and 41 metres, requiring intermediate skill levels and careful buoyancy control to navigate the terrain. Visibility ranges from 10 to 30 metres, with mild currents typically present. Divers should be aware of sharp coral and rocks throughout the area. The site supports a variety of Mediterranean reef fish and invertebrates within its varied topography. Given the depth profile, divers must monitor their gauges closely and plan conservative ascent profiles.

Elafonisi in Crete provides a gentle environment for beginner divers. The site consists of a mix of reef and seagrass habitats at depths ranging from 2 to 5 metres, with an average depth of 4 metres. Visibility is high, reaching up to 30 metres. The entry is from the shore, though divers should observe the surf break before entering. Currents are mild, allowing for a relaxed experience. The area supports a variety of Mediterranean reef fish and invertebrates typical of these habitats. On-site facilities include parking, toilets, showers, and a cafe. Arriving early in the morning is recommended for calmer surface conditions and fewer visitors.

Italian Cave in Rethymno, Greece, is a marine cavern and cave system accessible only by boat. The site features depths ranging from 20 to 35 metres, with an average depth of 20 metres. Divers encounter an overhead environment characterised by a distinct halocline, where a freshwater layer creates significantly colder temperatures than the surrounding saltwater. Water temperatures fluctuate between 16C and 22C throughout the year. Due to the overhead environment and the presence of a halocline, this site is suited for intermediate divers. Visibility at the site typically ranges from 10 to 30 metres, and currents are generally mild. Typical dive times are approximately 45 minutes.

Fresh Water Cave in Rethymno, Greece, is a shallow cave dive defined by the mixing of freshwater and seawater. This interaction creates a distinct halocline and thermocline, which can cause sudden shifts in water temperature and visibility. The cave reaches depths of 6 to 10 metres, with an average of 7 metres. Divers can access the site from both shore and boat, though shore entries require caution due to potential surf. Inside, the overhead environment necessitates careful buoyancy control to avoid sharp rock walls. A dive torch is recommended to navigate the limited natural light and observe the geological features of the cave structure.

Illigas Beach West in Rethymno, Crete, features a combination of reef and cave topography. Divers can access the site via shore or boat, encountering mild currents and visibility ranging from 10 to 30 metres. The site is suitable for intermediate divers, with depths extending from 15 to 30 metres. The reef gradually slopes into deeper water, requiring careful monitoring of depth gauges. A cafe is available on-site for convenience. Typical dives last approximately 45 minutes, and early morning visits are recommended to take advantage of the best visibility before boat traffic increases.
