Athens, Nea Makri: Guided Small Group Snorkeling Boat Trip

The best part of this outing is its small scale. From Nea Makri, you head by speedboat toward the quiet bays of Marathon Cape, then stop at Schinias Bay for clear water, a sandy beach, and a slower afternoon by the sea. Dimitris gives clear instruction and stays close in the water, which matters if you are new to snorkeling.

I like the two-stop plan: you get a proper snorkeling session at Marathon Cape and another chance to swim at Schinias Bay. I also like the friendly extras, including water, juice or tea, biscuits or fruit, and photos and videos. The main drawback is simple: the snorkeling itself may total about an hour, with the rest of the four hours spent cruising, taking a break, and enjoying the beach.

Quick takeaways

• Two coastal stops: Snorkel at Marathon Cape, then swim and explore around Schinias Bay.
• Very small group: The boat carries no more than seven participants, so Dimitris can offer personal help.
• Good for beginners: Equipment, basic instruction, and close support are included, but you must be a swimmer.
• A protected setting: Schinias Bay sits within Schinias National Park, away from the busiest parts of Athens.
• Useful comforts: Bottled water, juice or tea, biscuits or fruit, and trip photos are provided.
• Flexible booking: You can cancel up to 24 hours ahead for a full refund, and poor weather brings a choice of another date or a refund.

From Nea Makri to Marathon Cape by speedboat

Your meeting point is Kanelakis Diving Experiences at Frinis 20 in Nea Makri. If you are staying in Nea Makri, pickup from your hotel is available if you arrange it in advance. That is a useful touch, since getting to the starting point is easier when you do not need to work out local transport first.

The boat ride toward Marathon Cape takes about 20 minutes from Marathon Beach. The trip is part of the experience, not just a transfer. You will have open views across the water, a breeze off the coast, and time to settle into the outing before putting on your mask and fins.

The group limit of seven makes a real difference. You are not being moved through the water in a large line, and Dimitris can spend time showing you what to look for. His style, based on the details available for this trip, combines practical safety advice with stories about Greek history and the Marathon area.

The boat is described as a small motorboat, so expect a personal, fairly simple outing rather than a large cruise with extensive facilities. If you are sensitive to motion, the speedboat ride and wind are worth considering. Weather also affects the route. On one occasion, strong wind meant the boat could not go out, so the instructor used a shore-based snorkeling spot instead. The alternative still included sea life, snacks, water, and juice, but the change shows why the weather rule matters.

Marathon Cape: the first hour in the water

The first main stop is Marathon Cape, where you receive guidance before entering the water. You do not need previous snorkeling experience, but you do need to be comfortable in the sea. The trip is not suitable for non-swimmers, and children must be at least six years old and accompanied by an adult.

For a beginner, Dimitris is the most important part of this stop. He explains how to use the mask and fins, helps you feel at ease, and points out marine life rather than leaving you to search without direction. Several specific creatures have been seen on these outings, including starfish, octopus, sea cucumbers, and sea urchins. Sightings can never be promised, but the clear water gives you a fair chance to notice small life below the surface.

I would especially value the guidance if someone in my group was nervous. One family described an instance when a beginner became worried in the water, and Dimitris calmly helped and reassured her. That kind of attention is more useful than a polished speech before departure. It means the instructor is watching the group while also making the activity enjoyable.

The first snorkeling session lasts about an hour. That is enough time to learn the equipment, look around at a relaxed pace, and get a feel for the local sea. It is not a full-day water expedition, and experienced snorkelers who want several hours in the water may find it short.

The underwater setting is attractive, but you should set your expectations sensibly. The water has been praised for its clarity, and the area can offer interesting creatures close to shore. It is not necessarily comparable with the coral reefs or tropical fish of the Pacific Islands. This is a Greek coastal snorkeling trip, with its own appeal: rocky bays, Mediterranean sea life, and a guide who can explain what you are seeing.

A 15-minute break with simple Greek hospitality

After the first water session, there is a 15-minute break. Local snacks are included, usually biscuits or fruit, along with bottled water and either juice or tea. These are modest provisions, but they are exactly the sort of thing that helps after swimming, especially outside the hottest summer months.

One useful detail is that tea has been offered on colder outings. Sea temperatures can feel chilly in April and January, even when the air is pleasant. Bring a towel and dry clothes for the ride, and do not assume that summer clothing alone will feel comfortable after you leave the water.

This pause also gives the group a chance to talk. Since there are no more than seven people, the atmosphere should feel more like a shared outing than an organized beach crowd. Dimitris may also use this time to answer questions about the marine life, the coast, or the history of Marathon.

Schinias Bay and the protected coast

The second main stop is Schinias Bay. The program allows about an hour here for sightseeing, swimming, and snorkeling, followed by a 30-minute cruise back toward Nea Makri. The bay is known for its clear water and broad sandy beach, giving you a change of pace after the first snorkeling site.

This is where the trip works well for mixed groups. A keen snorkeler can look for marine life, while someone who has had enough time in the water can swim or sit on the sand. You are not locked into constant activity, which makes the outing easier for families and for people with different energy levels.

Schinias is also part of a protected natural area. That does not mean you should expect a completely untouched coast or a wilderness trip. It does mean the setting has more breathing room than a crowded city beach, and the beach stop adds a sense of place beyond simply checking off a snorkeling site.

One four-star assessment of the outing made a useful point: the beach and water were beautiful, with very few people around, but the participant would have preferred to keep snorkeling after the break instead of spending as much time swimming and looking around the beach. I think that is the key tradeoff here. If you want a balanced sea day, the plan is well judged. If snorkeling is your only goal, you may wish the water time were longer.

What Dimitris adds to the experience

Dimitris is repeatedly described as friendly, patient, and attentive. More important than general warmth, though, is the way he works in the water. He points out creatures, explains local wildlife, and helps participants use the equipment correctly.

He also brings in the wider setting. The outing can include stories about Greek myths, the history of Marathon, and significant events connected with the area. That gives the boat ride some substance. You are not just moving from one swimming point to another; you are getting context for the coast you are seeing.

The language options are English and French. That is helpful for French-speaking visitors, and the available feedback specifically notes that Dimitris was able to conduct the trip in French. His English has also been described as clear.

A particularly nice detail is that he does not appear to cancel the water experience simply because a booking is small. On one outing, only two people had booked, but he still took them snorkeling. The group size may vary, though the maximum is seven, so do not assume every departure will be private.

Is $100 a fair price?

At $100 per person, this is not the cheapest way to reach a beach near Athens. You are paying for a four-hour guided outing, speedboat transport, snorkeling equipment, instruction, refreshments, and photos and videos. Hotel pickup in Nea Makri is also available on request.

I think the price makes the most sense if you value guidance and convenience. Buying or renting equipment, arranging a boat, finding suitable bays, and planning transport to two coastal areas would take time and still would not give you Dimitris’s local help. The small group is another part of the value, especially for first-time snorkelers or families.

The price is harder to justify if you are an experienced snorkeler who mainly wants long periods in the water. The schedule includes boat rides, a snack break, and beach time, while one assessment found the total snorkeling time shorter than hoped. Those who want an intensive underwater session may prefer a trip built around more water time.

For a visitor based in Athens, the outing also offers a break from the city. It takes you toward the Marathon coast without the feel of a large organized excursion. That change of scene is part of what you are buying.

Who should book this boat trip?

I would recommend it most strongly to:

• Beginners who want instruction and someone nearby in the water
• Families with children aged six or older, provided the children can swim and remain with an adult
• Couples and small groups looking for a relaxed coastal outing
• French-speaking visitors who want help in French
• Anyone staying in Nea Makri who wants a simple half-day plan
• Snorkelers who enjoy learning about local animals and the area as much as swimming

I would be more cautious if you are a non-swimmer, want a long technical water session, or expect tropical reef conditions. The trip is not suitable for non-swimmers, and the sea life and underwater scenery are Mediterranean rather than Pacific-style.

Bring swimwear and a towel. I would also pack dry layers for the boat ride, particularly outside the warmest summer months. The operator supplies the mask, fins, water, snacks, and drinks, so you do not need to bring your own snorkeling kit.

The minimum age is six, but the adult in charge remains responsible for children. If anyone in your group is anxious in the water, tell the instructor early. The small group format gives Dimitris a good chance to offer extra support.

Weather, timing, and practical details

The trip lasts four hours, with starting times depending on availability. The schedule includes roughly 30 minutes of cruising toward Schinias Beach, an hour at Marathon Cape, a 15-minute break, an hour at Schinias Bay, and about 30 minutes cruising back. The exact order and timing may shift with sea conditions.

Weather is an important factor. If poor conditions make the boat trip unsafe or unsuitable, you will be offered another date or a full refund. Strong wind has previously led to a shore-based alternative rather than a normal boat departure. That is a reasonable safety decision, but keep some flexibility in your schedule.

Free hotel pickup is limited to hotels in Nea Makri and requires prior contact. If you are staying elsewhere, confirm how you will reach Frinis 20 before booking. Returning to Athens by taxi may require planning. A local restaurant has helped arrange a taxi in the past, but you should not treat that as guaranteed transport.

Cancellation is flexible up to 24 hours before departure for a full refund. You can also reserve and pay later, which helps if your Greek itinerary is still changing.

Should you book it?

Book this trip if you want a friendly, small-group introduction to Greek coastal snorkeling, with two swimming areas and plenty of help from Dimitris. The strongest reasons are the personal instruction, calm support for beginners, clear water, and the chance to see creatures such as octopus, starfish, sea cucumbers, and sea urchins.

Skip it if your priority is maximizing snorkeling minutes or finding tropical-style underwater scenery. The beach stop and boat cruising are genuine parts of the experience, not filler, but they mean less time in the water. For most visitors based in Nea Makri, I think the mix is a good value and a pleasant way to reach the Marathon coast without joining a large group.
