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.

Options include day trips, 2 days / 1 night and 3 days / 2 nights. Please be at the port at least one hour before departure for check-in and passport procedures, and follow any earlier reporting time stated on your ticket.

The Greek island facilitated-entry visa scheme is intended for eligible Turkish citizens travelling by sea from Türkiye to participating Greek islands. It requires an application and approval; it is not a visa that every traveller can obtain simply by arriving at the port.

Contact GÜVENTUR before booking to confirm whether the scheme is operating for your travel dates, the permitted stay, fees, required documents and submission deadline. Prepare your passport copy, biometric photographs, financial documents, return ferry booking and accommodation details as requested. Entry remains subject to the Greek authorities’ decision.

Browse the Lesvos tours or ferry tickets on the GÜVENTUR website. Open the product details, choose an available date and departure port, and review the programme, inclusions and conditions before completing your booking.

For help choosing a trip or checking availability, contact GÜVENTUR through the website’s contact or WhatsApp options. Your booking confirmation will include the relevant travel and document instructions.

The file generally includes a valid passport and copy, recent biometric photographs, the completed and signed application form, financial documents, a return ferry booking and accommodation confirmation. Additional documents may be required for your circumstances.

Ask GÜVENTUR for the current checklist and submission deadline before preparing your file. Passport validity, blank pages, photograph requirements and supporting documents must meet the Greek authorities’ current rules. Submitting documents does not guarantee visa approval or entry.

Travellers must carry a valid passport and meet the entry requirements applicable to their nationality and passport type. Turkish citizens holding ordinary passports generally need a valid Schengen visa or an approved visa under the Greek island facilitated-entry scheme, where available.

Visa exemptions apply to certain Turkish special, service and diplomatic passport holders. These rules do not apply automatically to travellers of other nationalities. Confirm your eligibility and current document requirements before booking; GÜVENTUR can assist with document checks and the application process.

GÜVENTUR can help arrange car rental on Lesvos. Port or hotel collection may be available, depending on the rental company, vehicle availability and your booking.

Book in advance, especially in busy periods. Before confirming, check the accepted driving licence, minimum age, deposit, insurance, collection point and return conditions with the rental provider. Turkish-language support is available through GÜVENTUR.

GÜVENTUR offers day trips, 2-day tours with 1 night and 3-day tours with 2 nights on Lesvos. Day trips usually return on the same day; overnight programmes allow more time to explore the island.

Depending on the itinerary, visits may include Molyvos, Petra, Plomari or Agiasos. Not every programme visits every destination. Check the selected tour page for the exact itinerary, accommodation, departure times and included services.

Children and infants need their own valid travel documents and must be included in the ferry booking. Visa requirements depend on the child’s nationality and passport type; being a child does not by itself create a visa exemption.

Child and infant fares, age limits and any visa-related charges vary by operator and programme. Check the selected trip and contact GÜVENTUR about the documents needed for minors, including any consent or accompanying-adult requirements.
