Explore the Underwater World of the Aegean


When you mention Lesbos Island, most people think of stone villages, ouzo, tavernas, olive groves, and crystal-clear bays. However, the island's worth-seeing beauty is not limited to land. Beneath the clear waters of Lesbos lie rocky reefs, cave-like formations, and rich marine life.

For those wishing to experience diving on the island through a professional organization, Black Rock Dive Centre offers various options ranging from beginners to certified divers. The center organizes PADI diving courses, daily guided dives, introductory dives, and snorkeling tours that families can also join.


Is Lesbos Island suitable for diving?

Lesbos is one of the largest islands in the Aegean Sea. With its long coastline and diverse bays, it has various dive sites accessible both from the shore and by boat.

The underwater landscape of the island includes:

  • Rocky bottoms,
  • Small reef areas,
  • Cave-like formations,
  • Seagrass beds,
  • Dive sites at different depth levels,
  • Various species of fish and invertebrates.

One of the major advantages of diving in Lesbos is the availability of options suitable for different experience levels. First-time divers can participate in controlled introductory dives, while certified divers can explore the deeper spots of the island with guided programs.

Discover Scuba Diving for first-timers

The most suitable option for those without a diving certificate and wishing to experience breathing underwater for the first time is Discover Scuba Diving, also known as the introductory dive.

This program is not a full diving certification. Participants are taught basic safety rules, equipment usage, underwater communication, and breathing techniques. Then, a controlled dive is conducted under the supervision of a professional instructor.

€70

Boat Introductory Dive – Boat

€130

The program lasts approximately 2–4 hours and can be undertaken from the age of 10.

The €70 shore option is an economical and easy start for guests diving for the first time. The €130 boat program appeals to those wishing to experience a dive site that cannot be accessed from the shore.

Before participation, the center evaluates health status and suitability for diving. Medical approval may be required for certain health conditions.


Guided dives for certified divers

Visitors with a valid diving certificate can join Black Rock Dive Centre's daily guided dives.

According to the center's published price list:

Guided Dive PackagePrice per person1 dive

€75

2 dives

€140

6 dives

€390

10 dives

€600

The total price for two guided dives in one day is €140 per person. This brings the average cost per dive to €70.


There is no separate four-dive package listed for someone wishing to do four dives. Calculated via two 2-dive packages:

4 dives = 2 × €140 = €280 per person

Four dives are usually spread over two days rather than squeezed into a single day, depending on physical fitness, dive depth, surface interval times, and the center's schedule. The exact plan must be agreed upon with the dive center in advance.

It is specifically noted that dive packages cannot be shared among different individuals.


What marine life can be seen underwater in Lesbos?

The visible marine life may vary depending on the season, dive site, depth, and sea conditions. According to Black Rock Dive Centre's promotional material, the following creatures can be encountered in the area:

  • Grouper,
  • Octopuses,
  • Crabs,
  • Shrimp,
  • Seahorses,
  • Eagle rays,
  • Sea turtles,
  • Various invertebrate marine animals,
  • Different Aegean fish species.

Dolphins are also mentioned as part of the local marine life; however, there is no guarantee that any specific species will definitely be seen during a dive. Observing marine life in its natural habitat is one of the most exciting aspects of diving.


Snorkeling tour for those who don't want to dive

For those who do not wish to go scuba diving or prefer a simpler water activity with their children, a Guided Snorkel Trip is a good alternative.

The list price for a guided snorkeling tour is €45 per person.

The snorkeling program includes necessary equipment, and participants are accompanied by experienced crew members. Buoyancy aids suitable for less experienced swimmers can also be used.

This activity is particularly suitable for:

  • Families,

  • Those wanting to observe the underwater world from the surface,

Attention for those who haven't dived in a long time

Having a diving certificate does not necessarily mean you can start a guided dive immediately after a long break.

The center's price list states that if more than 12 months have passed since your last dive, the Scuba Review program is mandatory. Safety diving guidelines also recommend additional training or skill refreshment after periods of inactivity exceeding six months.

Therefore, during reservation:

  • Last dive date,
  • Certificate level,
  • Total logged dives,
  • Health status,
  • Equipment to be rented
  • must be reported accurately.


How is diving safety ensured?

The safety rules shared by Black Rock Dive Centre are compatible with PADI's standard approach to safe diving.

Before every dive, checks are performed together with your dive buddy:

  • BCD and buoyancy system,
  • Weight belt or integrated weights,
  • Straps, buckles, and release mechanisms,
  • Tank, regulator, and alternate air source,
  • Pressure gauge,
  • Mask, fins, snorkel, compass, and dive computer,
  • General equipment layout.

No solo diving is allowed. Every diver goes down with a buddy, and communication is maintained throughout the dive.

Dive depth is determined according to the individual's training and experience level. Fundamental rules include not exceeding an ascent rate of 18 meters per minute and performing a safety stop of at least three minutes at a depth of approximately 5 meters.
