Athens, Nea Makri: Guided Small Group Snorkeling Boat Excursion

The best part of this four-hour outing is the change of pace. From Nea Makri, you leave the shore by speedboat and reach the quiet waters around Marathon Cape and Schinias Bay, where the day is shaped by clear water, rocky seabeds, sandy coves, and long stretches of open sea. Dimitris, the guide most often named by guests, leads the snorkeling and points out fish, anemones, sponges, starfish, and, if conditions cooperate, even an octopus.

I like the small maximum group of seven, which gives you real contact with the guide instead of a crowded, follow-the-leader swim. I also like the useful inclusions: masks, fins, wetsuits, life jackets, flotation noodles, bottled water, tea, fruit juice, snacks, and sometimes underwater photos. The main consideration is physical ability. Basic swimming skills are required, and one group found the boat and water time more demanding than expected, especially for older people and children.

Key points to know before booking

• Maximum of seven people: The small boat makes it easier for Dimitris to help with equipment and keep an eye on different skill levels.
• Two main water stops: Expect a rocky snorkeling area near Marathon Cape, followed by a calmer sandy beach area around Schinias Bay.
• A 20-minute speedboat ride: The trip begins from Marathon Beach and quickly carries you away from the built-up shore.
• Gear is supplied: Wetsuits, masks, fins, life jackets, and flotation noodles are available, but bring your own towel and swimwear.
• Good for beginners with basic swimming ability: Patient instruction is part of the outing, but this is not a passive sightseeing cruise.
• Weather matters: Wind and water temperature can affect comfort, visibility, and how enjoyable the swim feels.

Leaving Nea Makri by speedboat

The outing starts at Kanelakis Diving Experiences on Frinis 20 in Nea Makri, postal code 190 05. The activity ends back at the same meeting point. The tour information also highlights convenient hotel pickup and drop-off, so confirm the exact arrangement for your booking, especially if you are staying in central Athens rather than Nea Makri.

Once you have your equipment, the boat ride takes about 20 minutes. That short run is one of the pleasures of the trip. You get a fast, breezy look at the coast before stopping in the Marathon Cape area, rather than spending the whole afternoon beside the same beach.

The boat is a small speedboat, not a large excursion vessel. That keeps the group personal and makes it possible to reach smaller coves and quieter stretches of water. It also means you should be ready for a more active ride. Wind can make the trip feel rougher, and one account described a particularly windy day where the guide searched for a sheltered cove.

I would bring a light layer for the ride, even on a warm day. After swimming, the wind can feel cool when you are wet. You should also have dry clothes ready for the ride back or for lunch afterward.

Marathon Cape and the first snorkeling stop

The first water stop is the stronger choice for people who want to see marine life. The rocky seabed has anemones, sponges, fish, and other small creatures. Dimitris swims with the group and shows you what to look for, which matters in Mediterranean water where much of the interesting life is small and easy to miss.

This is not the sort of snorkeling where you float over a giant tropical reef. The appeal is subtler. You may notice an anemone tucked between rocks, a fish moving through seagrass, or the shape of a sea creature camouflaged against the bottom. Clear water helps, and the guide’s local knowledge adds purpose to the swim.

The boat remains nearby, and equipment is fitted before you enter the water. Wetsuits are supplied, along with masks and fins. Life jackets and noodle floats are available for people who need extra support. One particularly useful detail is that Dimitris has taken underwater photos during the swim and sent them afterward, although you should confirm whether this is included on your particular departure.

For a beginner, the first few minutes can feel like the hardest part. Adjusting to a mask, breathing through a snorkel, and swimming in open water takes a little calm practice. Dimitris has been praised for patient instruction, and the group size gives him time to help, but you still need basic swimming skills.

The water temperature deserves attention. On a mid-April trip, adults found wetsuits comfortable, while several children became cold after only a few minutes. Conditions will change with the season, but the lesson is simple: children who are new to snorkeling may need encouragement, shorter swims, or a warm-up on the boat.

Dispa Island and the quieter side of the coast

The route includes Dispa Island, one of the scenic points named for the trip. Depending on sea and wind conditions, the boat may use the island area as a calm place to enjoy the water and look below the surface.

The island stop adds variety. You are not spending all four hours at one beach, and the speedboat lets you see more of the coastline than a standard shore-based snorkeling session. Some people have described the area as peaceful and isolated, with good views into the water and room to relax on board.

The exact order of the stops can vary. The available details describe a rocky snorkeling area and a later beach stop, but do not promise a fixed sequence for every departure. That is normal for a small boat trip. The guide may choose a more sheltered cove if the wind picks up or conditions make another area less comfortable.

This flexibility is a strength, but it also means you should not expect a tightly scripted sightseeing tour. The day is built around safe water conditions, visibility, and the best available place to swim. If you want a fixed list of landmarks and timed photo stops, this may feel informal. If you like a guide who adapts the route, it works well.

Schinias Bay, sand, and time to slow down

Schinias Bay is the gentler half of the outing. The bay is part of a protected Natura 2000 area, known for clear water, sandy beaches, and a quieter natural setting. After the more focused snorkeling around rocks, this stop gives you time to swim, sit in shallow water, sunbathe on the boat, or simply rest.

The beach area is particularly useful for families and less confident swimmers. One family found the first rocky section too cold and intimidating for some children, but the kids later enjoyed swimming to the sandy beach and playing in the shallows while the adults snorkeled nearby. That is a good picture of how the stop works: it is less about spotting rare creatures and more about easy water time.

You may still see fish and seagrass in this area, but the marine life is less obvious than at the rocky stop. You need to look closely, and the main attraction is the calm setting. I would treat Schinias Bay as a relaxing beach break with some snorkeling, not as the main wildlife section.

The bay can also make the trip feel longer in a good way. Rather than rushing from one swim to the next, you have time to dry off, eat a snack, and enjoy the coast. Several people stayed close to an hour at the sandy stop. The precise timing can change, but the format allows for a proper pause.

What Dimitris adds to the outing

The guide is a major part of the value here. Dimitris has been described as friendly, patient, attentive, and comfortable explaining both the equipment and the local sea life. He also answers questions about the area and, during the boat ride, may share information about the coast and local history.

That personal attention is easier to provide with seven people than with a large boatload. If you are new to snorkeling, you can ask for help with the mask seal, fins, or breathing technique. If you already know what you are doing, you can spend more time looking around without a long line of swimmers in front of you.

The group size does not remove every challenge. The same outing may include children, first-time snorkelers, strong swimmers, and older adults. One disappointing experience came from a mismatch between the group’s ages and abilities and the level of effort expected in the water. Be honest about your comfort level before booking, and tell the guide if you need a slower pace or more flotation support.

Dimitris has also gone beyond the water in practical ways. Individual equipment, snacks, and drinks are provided, and some people received help with onward transport or a restaurant recommendation in Nea Makri. Those touches are not the central reason to book, but they make the day easier.

Equipment, snacks, and what to pack

The tour supplies the equipment you need for snorkeling. That includes masks, fins, and wetsuits, plus life jackets and noodle floats for extra support. The fitting process is part of the beginning of the activity, and the guide gives an explanation before you go out.

Bring your own towel. You should also arrive with swimwear already available and pack dry clothes for afterward. The boat has snacks and drinks, including bottled water, tea, fruit juice, fruit, and biscuits according to the details provided.

I would not count on the snacks as a full meal. They are useful after swimming, especially because several hours in the sun and water can leave you hungry, but you may want to plan lunch in Nea Makri after the tour. The area around the boat storage has restaurants, and Nea Makri itself offers a convenient place to eat after returning.

If you have a preferred mask or snorkel, you can ask whether bringing it is suitable, but supplied equipment is part of the service. Children can use flotation noodles, though they still need to be comfortable in water and accompanied by an adult.

How difficult is the snorkeling?

The operator lists basic swimming skills as a requirement, and that should be taken seriously. You do not need advanced snorkeling experience, but you should be able to manage yourself in the water with guidance and equipment.

The trip is best for people who want an active half-day, not for someone who wants to remain on the boat. You may spend around two hours in the water across the stops, with time split between snorkeling, swimming, and relaxing. Wind, waves, water temperature, and your own comfort can change how strenuous that feels.

Children must be at least six years old and accompanied by an adult. The minimum age does not mean every six-year-old will enjoy the outing. Young children who have never worn a snorkel mask may resist the first swim, especially in cool water. A confident child who likes swimming may have a great time, but I would prepare younger children for a new sensation rather than promising an easy pool-style activity.

The tour can work for older participants too, provided they can swim and are comfortable getting in and out of a small boat. If anyone in your group has limited mobility, serious water anxiety, or difficulty with boat movement, contact the operator before booking. The available information says most people can participate, but it does not promise a specialized accessible setup.

Is $102.80 a fair price?

At $102.80 per person, this is not the cheapest way to visit a beach near Athens. The value comes from what is bundled into the four hours: a small speedboat, an instructor, snorkeling equipment, wetsuits, water time at several coastal locations, snacks, drinks, and the chance to ask questions throughout the trip.

A larger boat tour might cost less per person, but it would not offer the same level of personal attention. A private boat charter would normally cost much more, so this small-group format sits between a mass excursion and a fully private trip.

The price makes the most sense if you are staying in or near Nea Makri, want a guided introduction to Mediterranean snorkeling, and value a compact group. It is less attractive if you only want a quick swim or if getting to Nea Makri from central Athens takes a large amount of your day.

The trip is often booked about 30 days ahead, so I would not leave it until the last minute during a busy season. Confirmation is sent within 48 hours, subject to availability. Free cancellation is available until 24 hours before the start time. Inside that window, refunds are not offered, and weather or minimum-group cancellations are handled with a new date, another experience, or a full refund.

Who should book this Nea Makri boat trip?

I would recommend it to:

• Couples who want a half-day on the water away from central Athens
• Families with children who already have basic swimming skills
• First-time snorkelers who want patient instruction
• Experienced snorkelers who prefer a small group and local guidance
• People staying near Nea Makri, Marathon, or the northeast Athens coast
• Anyone who likes combining a short boat ride, wildlife viewing, and beach time

I would think twice if you dislike speedboats, get cold easily, cannot swim, or want a guaranteed large concentration of marine life. The sea is natural, not a controlled aquarium. You may see fish, anemones, sponges, starfish, seagrass, and an octopus, but sightings and visibility depend on conditions.

Final verdict: book it if you want personal guidance

I would book this outing if my priority were a friendly, small-group day on the Aegean with a real guide rather than a crowded boat and a quick swim. Dimitris receives especially strong praise for patient teaching, clear explanations, and thoughtful help before and after the water time.

The best plan is to arrive prepared for an active afternoon: bring a towel, swimwear, dry clothes, and realistic expectations about cool water and changing wind. If your group includes children or mixed swimming abilities, contact the operator ahead of time and explain your needs.

Choose this trip for its personal scale, flexible route, and mix of rocky snorkeling and sandy-bay relaxation. Skip it if you need a completely effortless activity or a guaranteed reef-style display of sea life.
