Adventure Dives for Certified Divers in Nea Makri, Athens
The best part of this Athens-area experience is the quick change from city sightseeing to shipwrecks, caverns, and steep underwater walls. From Marathon Beach, a speedboat reaches sites near Platourada Island, Dipsa Island, and Marathon Cape in about 20 minutes.
I like the small maximum of five people, which gives Dimitris room to adjust the pace and help you regain confidence if your certification has sat unused. I also like the practical backup plan: when wind cancels the boat, the team can often shift to a sheltered shore site instead. The main drawback is getting to Nea Makri from central Athens, especially with traffic.
Key points to know
- Speedboat access in about 20 minutes: Sites sit within roughly 6 miles of Marathon Beach.
- Several types of underwater scenery: Expect wrecks, caverns, walls, slopes, and old maritime remains.
- A good refresher for lapsed certified participants: Dimitris can review equipment use, buoyancy, and basic theory.
- Two-outing option with a 1.5-hour surface break: Snacks and drinks are provided between outings.
- Weather can change the plan: A shore outing may replace the boat trip, or the activity may be rescheduled.
- Equipment is supplied: The center uses Cressi buoyancy compensators, regulators, and wetsuits.
From Athens to Marathon Beach in 45 minutes

Kanelakis Diving Experiences is at Frinis 20 in Nea Makri, about 45 minutes from the heart of Athens under normal conditions. That makes this a useful choice if you want time in the water without committing to a full island trip.
The location is also the main practical catch. Nea Makri is not beside the Acropolis or central Plaka. One direct public transport option described by the operator runs from the Nomismatokopia metro area to Nea Makri by KTEL bus. The one-way cost is about $4.50, and the bus ride can take around 45 minutes depending on traffic.
If you are using public transport, allow extra time. One participant arrived late because of delayed transport and traffic, and Dimitris let the couple wait at the center with water and snacks. That is a kind touch, but I would not build a tight Athens sightseeing schedule around the start time.
The meeting point is also the return point. From there, you prepare your equipment before heading to Marathon Beach. The activity lasts about four hours, though exact timing depends on the chosen outing, sea conditions, and whether you do one or two descents.

What the speedboat trip adds

The boat covers the short run from Marathon Beach to sites within a 6-mile radius. The ride to the underwater sites takes about 20 minutes, so you spend more time exploring and less time bouncing across open water.
The three named areas offer different possibilities:
- Platourada Island: A nearby island setting for underwater scenery and marine life.
- Dipsa Island: Another short boat run with access to the gulf’s rock formations and submerged features.
- Marathon Cape: A coastal site where slopes, walls, and maritime remains may shape the route.
The exact site is not fixed in the information provided, and that is important. The guide chooses based on conditions and the type of underwater outing planned. A sheltered area may be the sensible choice on a windy day, while calmer weather can open the way to a more ambitious boat location.
You should expect the guide to brief you before entering the water. The activity is for certified scuba participants, and you must show evidence of certification. A health questionnaire is required before going in. Conditions such as asthma or heart problems may prevent participation, so check with your doctor if you have a medical concern.
Shipwrecks, caverns, and old maritime remains

This is not simply a swim over a sandy bottom. The area is described as having wrecks from different eras, dramatic walls, caverns, and slopes marked by old maritime remains.
That variety matters. You may spend one section following a rock wall, then move toward a cavern or inspect a wreck. The appeal is less about one famous underwater monument and more about having several kinds of terrain within a compact area.
You should keep your expectations sensible. The supplied information does not name specific wrecks, give their dates, or promise a particular ship at every outing. The route depends on conditions and local judgment. Still, the mix of natural rock and human history gives the session more character than a standard open-water practice site.
The water is described as warm, with good visibility and plenty of marine life. Those conditions can make the outing easier to enjoy, especially if you are rebuilding comfort after time away from scuba. You can spend less mental energy fighting the cold and more time watching the rock formations, sea life, and wreck details around you.
A useful refresher for certified participants

You need certification, but you do not need to be a recently active expert. One particularly useful feature is the guide’s willingness to refresh old skills before the outing begins.
Dimitris has helped certified participants review equipment, basic theory, buoyancy control, and fin technique after several years away from the water. That makes this a good fit if your card is current but your confidence is not.
The pace can also be adjusted. On one shore outing, Dimitris continued guiding until the participant reached the agreed air threshold rather than cutting the session short simply to follow a rigid timetable. That suggests a practical approach to air use and personal comfort, though you should still discuss your limits and plan before entering the water.
The small group size helps here. With a maximum of five people, the instructor has a better chance of noticing a nervous participant or answering questions without rushing. It is not a private lesson, but it is a far more personal setup than a large boat carrying a crowd.

One outing or two, with time to reset
You can choose the length of your trip. The double-outing option includes a 1.5-hour surface interval between sessions, with drinks and snacks.
That pause is not wasted time. A proper break lets you warm up, eat, drink, discuss the first route, and decide what you want from the next one. It also supports safe planning between descents. If your first session uses more air than expected or leaves you tired, the interval gives you time to assess how you feel.
The exact snacks and drinks are not specified, so do not treat this as a meal. Bring your own towel and swimwear, as advised. You should also arrive ready for a water-based activity rather than assuming every personal item will be supplied.
A single outing may suit you if you have limited time in Athens or if you are returning to scuba after a long break. Two outings make better value if you want to compare sites and settle into the equipment after the first session.
What happens when the weather turns

The southern Evoikos Gulf can offer sheltered water, but boat plans still depend on the weather. If wind or waves make the original route unsafe, the team may shift to a protected shore location.
That flexibility has real value. One planned two-outing boat trip became a shore outing because of poor weather, yet the participants still received an underwater session and saw the local terrain. Another boat plan was replaced with a single outing in a sheltered bay.
You should not book this if you need a guaranteed boat ride to a particular island. You should book it if you care more about getting safely into the water than about following a fixed route. The fallback is not identical to the advertised boat experience, but it can save the day when conditions change.
If the weather is too poor for the activity, you will be offered another date or a full refund. The same applies if the minimum number needed to run the activity is not reached.
Equipment and preparation at the center

All dive equipment is provided. The center uses Cressi buoyancy compensators, regulators, and wetsuits, and the equipment is described as clean and well maintained.
You should still bring your own towel and swimwear. Evidence of certification is required, and children must be accompanied by an adult. Service animals are allowed, and the meeting point is near public transportation.
Do not plan to fly within 12 hours after the activity. That restriction is especially important if you have a late flight from Athens. Schedule the outing early enough in your trip to leave a safe buffer before flying.
The health questionnaire is not a formality to ignore. Some medical conditions can prevent participation, and the operator specifically advises consulting a doctor about issues such as asthma and heart conditions.
Is $66.01 good value?

At $66.01 per person, this is fairly priced for a roughly four-hour certified scuba outing that includes equipment, a guide, boat transport when conditions permit, and refreshments during the break between two sessions.
The value improves if you need gear. Renting a buoyancy compensator, regulator, wetsuit, and related equipment separately can quickly add cost, while the small group keeps the instruction personal.
The price is less attractive if you only want a guaranteed boat excursion or if reaching Nea Makri requires an expensive private transfer. Public transport can keep the cost down, but the journey takes time and traffic can interfere with a precise schedule.
Compared with the cost of an island excursion from Athens, this is a focused way to get underwater without spending a full day traveling. You pay for access to local sites, not for a broad sightseeing program above the water.
Who should book this experience?

I would recommend it most strongly to:
- Certified participants who have not been underwater for several years.
- People who want a small group and direct guidance.
- Visitors with enough time to travel to Nea Makri and return.
- Scuba participants interested in wrecks, caverns, walls, and marine life.
- Couples or small groups who value a flexible plan.
- Anyone willing to accept a shore outing if weather cancels the boat.
I would be more cautious if you are a beginner without certification, have a flight within 12 hours, or need to return to central Athens at an exact time. The experience is also not ideal for someone who views a shore replacement as a disappointment rather than a sensible safety choice.
Booking, cancellation, and timing tips
Confirmation arrives within 48 hours of booking, subject to availability. The activity is offered in English, and mobile tickets are accepted.
You can cancel for a full refund up to 24 hours before the start time. Cancellations or changes made inside that window are not refunded or accepted. Since weather can affect the boat route, keep your schedule flexible and avoid placing this on the final day before a flight.
The activity is often booked well ahead, with an average booking lead time of about 48 days. That does not guarantee it will sell out, but it is a useful signal if your Athens dates are fixed.
FAQ
Where does the experience start?
You meet at Kanelakis Diving Experiences, Frinis 20, Nea Makri 190 05, Greece. The activity ends back at the same meeting point.
How far is the site from central Athens?
The center is about 45 minutes from the heart of Athens under normal conditions. Public transport from the Nomismatokopia metro area to Nea Makri takes about 45 minutes by KTEL bus, depending on traffic.
Do I need scuba certification?
Yes. You must provide evidence of scuba certification before participating.
How many people can join?
The maximum group size is five participants.
Is equipment provided?
Yes. All dive equipment is provided, including Cressi buoyancy compensators, regulators, and wetsuits.
Can weather change the boat trip?
Yes. Poor weather may lead to a sheltered shore outing, a different date, or a full refund if the activity cannot operate.
Can I fly after the experience?
Flying within 12 hours after the activity is not recommended. Plan your schedule with that restriction in mind.
Should you book it?
Book this if you are a certified scuba participant who wants a practical Athens-area outing with small-group guidance and flexible site choices. The mix of wrecks, caverns, walls, and marine life gives you more variety than a basic practice session, while Dimitris’s patient instruction can help you settle back into the equipment.
Skip it if you need a guaranteed boat route, have little spare time for the trip to Nea Makri, or are flying soon afterward. For everyone else, the $66.01 price is strong value, especially when you count the supplied equipment, boat access, refreshments, and the option to continue from a sheltered shore site when the sea refuses to cooperate.
