Warm-water scuba diving off the protected Yumurtalık lagoons and the Gulf of İskenderun, exploring seagrass meadows, rocky reefs and abundant Mediterranean fish on the quiet eastern edge of the Adana coast.
Scuba diving off the Yumurtalık coast, on the far eastern arm of Adana province along the Gulf of İskenderun, offers warm, clear Mediterranean waters and a comparatively uncrowded underwater environment far from the busier resort dive sites of Antalya and Fethiye. The Yumurtalık bay and lagoon system — a Special Environmental Protection Area — contains protected Posidonia oceanica seagrass meadows, rocky reef structures and a varied assemblage of Mediterranean marine life including octopus, scorpionfish, moray eels, grouper, sea bream and occasional loggerhead sea turtles.
Dive sites are accessed by short boat rides from the Yumurtalık shoreline. The underwater topography is generally gentle, with sandy bottoms giving way to rocky outcrops at 5–20 m depth, making the area well suited to open-water certified divers and those undertaking discover-scuba introductory dives. Visibility typically ranges from 10 to 20 m in summer and is best in June, September and October after summer stratification stabilises the water column. Water temperature reaches 26–28 °C at the surface in July and August, requiring a 3 mm wetsuit; a 5 mm suit is more comfortable for longer or deeper dives and for October visits.
Yumurtalık dive centres provide full equipment rental — BCD, regulator, tank, wetsuit and weights — as well as PADI or equivalent certification courses and guided boat dives for certified divers. Full Open Water and Advanced certification courses can typically be completed in three to four days. Visitors with their own gear should bring a certification card and logbook; centres require proof of certification before providing tanks. Introductory discover-scuba sessions are available for non-certified visitors and are conducted in sheltered shallow water with a dedicated guide.
The dive season runs June through October, peaking in August for warmth and in June and September–October for clarity. The site is recommended for divers seeking a quieter, less commercialised eastern Mediterranean alternative; boat traffic on Yumurtalık bay is significantly lower than at major resort dive hubs.

Tips for visiting
- Book gear rental in advance for July and August — wetsuit sizes run limited and popular BCD configurations may not always be available
- Bring a certification card and logbook; Yumurtalık dive centres require proof of certification before issuing tanks to self-organising divers
- A 3 mm full wetsuit is adequate in July–August; bring or rent a 5 mm for October dives when surface temperature drops to around 22 °C
- Request a morning dive slot for the best visibility — afternoon boat traffic on the bay can temporarily stir surface sediment near the jetties
- Macro subjects (nudibranchs, seahorses, pipefish) are the area's strength underwater; bring a macro wet-lens if diving with a compact camera housing
When to visit
June through October is the dive season, with June and September offering the best water clarity. July and August are warmest and suit those prioritising comfort; visibility is slightly reduced at peak summer. October is ideal for experienced divers seeking cooler water, excellent Posidonia visibility and fewer boats.
Accessibility
Dive centres at Yumurtalık are located on the harbour front and accessible by road; the pier area used for boat departure is manageable for most ambulant visitors. Full scuba diving requires the ability to gear up on a boat deck and enter and exit the water by giant stride or ladder — not accessible to wheelchair users without specialist assistance. Discover Scuba sessions in very shallow water may be arranged for participants with some mobility limitations with advance notice to the operator.
Frequently asked questions
Do visitors need a scuba certification to dive at Yumurtalık?
Certified divers (PADI Open Water or equivalent) can participate in all guided boat dives. Non-certified visitors can book a Discover Scuba Diving introductory session, which involves a pool briefing and a shallow supervised dive typically to 5–6 m. Full Open Water certification courses are also available at local dive centres.
What marine life can be expected on Yumurtalık reef dives?
Common sightings include octopus, moray eels, scorpionfish, grouper, sea bream, rainbow wrasse and various reef perches. Posidonia meadow dives turn up seahorses, pipefish and nudibranchs. Loggerhead sea turtles are occasionally observed resting on sandy patches, particularly in summer months. The Gulf of İskenderun's eastern position produces a slightly different species mix from western Mediterranean dive sites.
What is the best time of year to dive at Yumurtalık?
June through October constitutes the diving season. June and September–October offer the clearest visibility (15–20 m) as summer thermoclines stabilise the water column. July and August are warmest (26–28 °C surface) but visibility can dip to 10–12 m due to plankton blooms. Commercial dive operations typically cease from November through May due to rough conditions.
Is Yumurtalık bay a protected marine area?
The Yumurtalık bay and adjacent lagoon system is designated as a Special Environmental Protection Area (Özel Çevre Koruma Bölgesi), which restricts certain coastal development and industrial activity. Dive operators within the protection zone are expected to comply with environmental guidelines, including no anchoring on Posidonia meadows and no collection of marine organisms.
