Athens, Nea Makri: Guided Small Group Snorkeling Boat Trip

The best part of this four-hour boat trip is the change of scene. From Nea Makri, you ride out toward Marathon Cape, swim in clear water, then spend time on the sandy shore at Schinias Bay. It feels far removed from central Athens, even though the outing is easy to fit into a day near the capital.

I like the small groups of no more than seven and the calm, attentive way Dimitris works with beginners. I also like that the price includes the full kit, water, juice or tea, snacks, and photos and videos. The main drawback is simple: this is a pleasant Greek coastal snorkeling trip, not a tropical reef adventure. One recent participant also wanted more time in the water instead of time on the beach.

Key points to know before booking

• Dimitris leads the trip: He provides safety guidance, explains how to use the equipment, and points out sea life and local history.
• Two water stops: You snorkel near Marathon Cape, then spend more time swimming or snorkeling at Schinias Bay.
• Limited to seven people: The small boat and group make it easier to ask questions and get help.
• About one hour of snorkeling at each main stop: The schedule also includes boat rides, a short snack break, and beach time.
• All basic equipment is supplied: Bring only swimwear and a towel, though you may want extra sun protection.
• Weather can change the plan: Strong wind has sometimes prevented the boat trip, with a shore-based alternative or another date offered instead.

A coastal escape from Athens

Nea Makri sits on the eastern coast of Attica, in the wider Marathon area. That location matters. You are not simply standing on a crowded city beach for a quick swim. You are heading along a stretch of coast tied to the Marathon story, with open water, small bays, and the protected setting of Schinias National Park.

The trip begins at Kanelakis Diving Experiences on Frinis 20. If you are staying in Nea Makri, free hotel pickup is available by prior arrangement. That can save you a taxi ride and removes some morning fuss, but you need to contact the operator before the day of the trip.

The boat ride from Marathon Beach toward the first snorkeling area takes about 20 minutes. The speedboat gives the outing a little energy without turning it into a full-day cruise. You get views of the coast, a breeze across the water, and time to settle into the rhythm of the trip before putting on your mask and fins.

The pace is one of the strongest features. You are not rushed from one photo stop to another. About four hours allows enough time for two water sessions, a beach stop, and the return ride, while still leaving you part of the day for lunch or other plans.

What happens near Marathon Cape

The first main stop is around Marathon Cape, where the guide chooses a suitable bay for swimming and snorkeling. The water is described as clear, and the sheltered coves can offer good conditions for seeing smaller marine life close to shore.

Dimitris gives basic instruction before you enter the water. That is useful if you have snorkeled only once or twice, since a poorly fitted mask or uneasy breathing can spoil an otherwise lovely outing. The equipment is supplied, and the guide remains involved rather than sending everyone off alone.

The sea life mentioned on this trip includes starfish, sea cucumbers, sea urchins, octopus, and fish. You might not see every creature on every departure, since underwater visibility and conditions change. Still, the guide’s habit of pointing out small animals is important. A sea cucumber or tiny octopus is easy to miss when you are looking only for large fish.

Dimitris also adds information about the area, Greek history, and local sea life. His English is described as strong, and he can also lead the trip in French. For you, that means this is not just time in the water. You receive enough explanation to understand what you are seeing and where you are.

The first snorkeling session lasts about an hour. That is a generous block for a short coastal tour, especially if you are a beginner who needs time to adjust. Some people may find the pace ideal. Strong swimmers who want constant time in the water may wish the program stayed wet for longer.

The 15-minute break and small touches

After the first water stop, the boat pauses for about 15 minutes. Biscuits or fruit, bottled water, and juice or tea are included. These are small provisions, but they matter after swimming, especially if you are traveling with children old enough to join the trip.

One especially useful detail is the hot, sweet tea provided on colder days. A spring or winter outing can be much cooler than the Greek summer suggests, and the water may feel cold even when the sun is bright. The trip has operated in January and April, so do not assume this is only a July and August activity. If you go outside the warmest months, bring a towel and use the break to warm up.

The boat is not presented as a luxury vessel. Its appeal is its size and function. With a maximum of seven participants, you have room to talk with the guide and to get help with your mask or fins. It also avoids the impersonal feel of a large excursion boat.

Schinias Bay and the protected coast

The second major stop is Schinias Bay, beside Schinias National Park. The bay combines a sandy beach with clear water, so you have a choice. You can snorkel again, swim, or simply sit on the beach and enjoy the coast.

This is where the outing becomes more relaxed. The first stop focuses on getting into the water and seeing marine life. Schinias gives you time to slow down. If your group includes mixed ages or mixed swimming ability, that flexibility is helpful. One person can rest on the sand while another spends more time in the water.

The beach is described as clean and lightly used during the excursion, though conditions and crowds can vary. The setting is a protected natural area, not a private beach reserved for the tour. You should therefore expect a natural coastal stop rather than beach-club service, loungers, or a full range of facilities.

A useful point of honesty: snorkeling quality here is good for a Mediterranean coastal outing, but it should not be compared with the coral reefs of the Pacific or Caribbean. You can see interesting creatures and enjoy clear water, but the attraction is the whole combination of boat ride, quiet bays, guide, beach, and local setting.

The second water session is scheduled for about an hour. Afterward, the boat cruises back toward Nea Makri for roughly 30 minutes, with scenic views along the way. The ride home is a pleasant way to finish, though anyone prone to seasickness should be aware that a speedboat can feel lively in wind or waves.

Why Dimitris makes a difference

The guide is central to the quality of this experience. Dimitris is repeatedly described as friendly, patient, and careful about safety. That shows in practical ways: he explains the gear, stays attentive in the water, answers questions, and helps people who feel nervous.

One beginner had a moment of panic in the water and received calm reassurance. That detail matters more than a long list of qualifications. Snorkeling requires you to breathe through a tube while your face is in the water, and not everyone finds that natural. A guide who remains close and composed can turn an uncomfortable moment into a manageable one.

Dimitris also takes time to show what he finds. He has pointed out small creatures, including octopus and sea stars, and has explained local history along the coast. He may even bring an animal close enough for you to see clearly, but you should treat sea life gently and follow his instructions.

The language options are English and French. If you are more comfortable in French, that can make the safety briefing and explanations easier to follow. The group size also means you are not lost in a crowd if you need to ask for a mask adjustment or a repeat explanation.

The real value of the $100 price

At $100 per person, this is not the cheapest way to reach a beach near Athens. The value comes from what is included and from the structure of the outing.

You receive:

• Speedboat transportation during the activity
• A guide and snorkeling instruction
• Mask, fins, and other needed snorkeling equipment
• Bottled water
• Biscuits or fruit
• Juice or tea
• Photos and videos from the trip
• Hotel pickup in Nea Makri, if arranged in advance

If you rented equipment, arranged a boat, paid for instruction, and bought refreshments separately, the costs would add up quickly. The small group is also worth considering. A seven-person maximum gives you a much more personal outing than a large boat cruise.

The price is easier to justify if you are staying in Nea Makri or the Marathon area and want a guided half-day on the water. It is less compelling if you are staying in central Athens and only want a quick swim, since you must first reach the departure area and return afterward.

Past participants have sometimes paid for a taxi between Athens and Nea Makri. The exact fare can vary, and arranging the return ride may take effort. If you are not staying locally, plan your transport before the morning begins. The operator’s free hotel pickup applies to hotels in Nea Makri, not automatically to central Athens.

Who should book this outing

This trip suits beginner and intermediate snorkelers who want guidance rather than a self-guided beach stop. The instructor can explain the equipment, stay near the group, and help you notice small animals.

It also works well for families with children six and older, provided the children are accompanied by an adult and can swim comfortably. A 12-year-old has enjoyed the trip, and the beach break gives younger participants a chance to rest. Children under six cannot join, and the outing is not suitable for non-swimmers.

Couples and small groups will appreciate the intimate format. If only two people book, the trip may still go ahead, as has happened before. That can make the boat feel almost private, though you should confirm the operating arrangements when booking.

This is less suitable if you want a serious underwater sports session, long uninterrupted snorkeling, or dramatic tropical coral. It is also not the right pick if you dislike boats or are uneasy in open water. The outing depends on safe weather, and the route can change when wind affects the sea.

Weather, seasons, and what to pack

The boat trip is subject to favorable weather. Strong wind has prevented the boat from going out on some occasions. In that case, the operator may offer another date or a full refund. At times, the instructor has instead taken the group to a shore-based snorkeling site, where sea life such as starfish and sea cucumbers could still be seen.

That flexibility is useful, but you should not book this as your only fixed activity on a tight schedule. Leave room for a weather change, especially outside summer.

Bring swimwear and a towel. You should also think about sun protection, though the supplied information specifically requires only those two items. The boat and beach provide sun exposure, so a hat, sunscreen, and a cover-up are sensible additions.

The water temperature can vary sharply by season. April and January departures have been possible, but colder months may require a more determined approach to swimming. The included tea and snacks help, yet you should choose the season based on your comfort in cool water, not just the air temperature.

Cancellation is free up to 24 hours before the activity, and you can reserve now and pay later. Those terms are helpful when your Athens plans depend on weather or transport, but they do not remove the need to check the start time and arrange your route to Frinis 20.

My verdict: a good half-day by the sea

I would book this trip if I wanted a personal introduction to the coast east of Athens, especially while staying in Nea Makri. The combination of two snorkeling locations, a quiet beach, local stories, and a guide who pays attention to nervous beginners gives the outing real substance.

I would not book it expecting a world-class reef. The sea life is interesting, the water can be beautifully clear, and the coastline is appealing, but the Mediterranean setting has limits. You may spend nearly as much time cruising and resting as snorkeling, which is a benefit for some people and a drawback for others.

The strongest reason to choose it is Dimitris. His calm instruction, safety focus, French and English language skills, and habit of showing you small creatures make the experience easier and more rewarding. If you are comfortable with the $100 price and can reach Nea Makri without a transport headache, this is a friendly, well-paced way to spend half a day on the Marathon coast.
