Athens, Nea Makri: Guided Small Group Snorkeling Boat Excursion

The best part of this four-hour outing is its setting: a small speedboat carries you from Marathon Beach to clear coves, rocky shallows, and the protected waters of Schinias Bay. Dimitris, the guide most often named by guests, teaches beginners patiently and points out anemones, sponges, fish, starfish, and sometimes an octopus.

I like the maximum group size of seven, which gives you real contact with the instructor instead of a crowded-water outing. I also like the mix of active snorkeling and quiet boat time, plus wetsuits, masks, fins, snacks, drinks, and children’s float aids. The main caution is that this can feel strenuous for weak swimmers or anyone expecting a gentle sightseeing cruise. Basic swimming skills are required, and spring water may be cold.

Key points to know before you book

• Two different water stops: Expect a rocky area with marine life, followed by a shallower sandy beach in Schinias Bay.
• Small boat, small group: The boat carries no more than seven people, allowing close instruction but limited room to move around.
• Dimitris leads the water time: He helps fit equipment, explains the local sea life, and guides beginners through the snorkeling.
• Gear and refreshments are included: Wetsuits, masks, fins, life jackets, noodle floats, water, tea, juice, biscuits, and snacks have been provided on past trips.
• Bring your own towels: Swimwear, dry clothes, and a towel are not supplied.
• Meet in Nea Makri: The stated meeting point is Kanelakis Diving Experiences, Frinis 20, Nea Makri. Confirm any hotel pickup before booking.

A half-day on the Marathon coast

This is not a long cruise around the Saronic Gulf. It is a focused morning or afternoon on the coast northeast of Athens, built around two things: snorkeling and time on the water.

You meet at Frinis 20 in Nea Makri, at the Kanelakis base. The excursion lasts about four hours and ends back at the meeting point. The advertised highlights include Dispa Island, Marathon Cape, and Schinias Bay, while the practical water itinerary centers on a rocky snorkeling area and a sandy beach stop.

The trip begins with roughly a 20-minute speedboat ride from Marathon Beach. That short run matters. You get a quick burst of open-water speed, then reach quieter places that would be harder to access from shore. The boat is small, so you should expect a direct, informal outing rather than the facilities of a large day cruise.

A certified instructor helps you choose and fit the mask, fins, and wetsuit. Dimitris has been singled out for patient instruction, friendly communication, and his habit of pointing out small creatures below the surface. If you have never snorkeled before, that personal guidance is one of the strongest reasons to choose this trip.

The first stop: rocky water near Marathon Cape

The first snorkeling area is usually the more interesting stop for marine life. Expect rocky seabed, anemones, sponges, fish, and other small creatures. With good visibility, you may be able to examine details that disappear in deeper or murkier water.

This is also the part most likely to test your comfort in the sea. You enter from the boat rather than simply walking into shallow water from a beach. Life jackets and noodle floats are available, but you still need basic swimming ability.

Dimitris guides the group in the water and helps identify what you are seeing. His explanations add value because Mediterranean snorkeling is often about noticing small things: an anemone tucked among rocks, a starfish resting on the seabed, or fish moving through seagrass. This is not a tropical reef trip, and you should not book it expecting clouds of colorful fish. The appeal is closer inspection of local coastal life in clear water.

The time in the water can be substantial. One account describes about an hour at the first anchorage, while the full trip may allow roughly two hours in the water across both locations. The pace depends on the group, conditions, and comfort levels.

Dispa Island and the boat ride between bays

Dispa Island is included among the excursion’s featured places. The exact amount of time spent there can vary, but the island helps give the outing a sense of discovery beyond a single beach swim.

The boat ride itself is part of the attraction. You see the coast from low on the water, with rocky edges, small coves, and open views around Marathon Cape. Wind can affect the ride and the snorkeling conditions. On a windy day, the crew may choose a more sheltered cove, which can mean a calmer swim but a change from the planned setting.

The vessel is a compact speedboat. That makes it nimble and well suited to reaching small bays, but it also means the ride may feel exposed and active. Bring a light cover-up or dry clothes for the return ride, especially outside the hottest summer months.

The second stop: Schinias Bay and its sandy beach

The Schinias stop changes the mood. After the rocky snorkeling area, the boat heads toward shallow water and a sandy beach in the protected Schinias Bay area.

This is the easier part for children and first-time snorkelers. The water near the beach is shallower, and you can swim, wade, relax, or simply sit on the sand while others snorkel nearby. Seagrass beds may be visible, though the marine life can be less obvious than at the rocky stop. You might need to look carefully rather than expect an instant show.

Plan on a long, restful pause here. Past outings have spent close to an hour at the beach. That gives you time to warm up, settle down, and enjoy the surroundings without being rushed from one activity to the next.

Schinias is part of a protected Natura 2000 area. The value is not just the water clarity. The bay offers a quieter natural setting, with sandy shore and open space that feels far removed from central Athens. If you want nonstop snorkeling, this beach stop may seem slow. If you like combining sea time with an easy swim and sunbathing, it is a welcome balance.

What the equipment and instruction are really like

The price includes the basic equipment needed for the activity: wetsuit, mask, snorkel, and fins. Life jackets and noodle floats are also available, including float aids suitable for children.

The wetsuit is useful even when the air feels warm. Water can be chilly in April and during windy periods, and several people have found the water cold despite wearing wetsuits. Children may feel the cold faster than adults. If your child is new to masks or uncomfortable in open water, prepare for a slow start rather than assuming they will immediately enjoy the first stop.

Dimitris’s instruction is a strong feature for beginners. He explains how to use the equipment, stays involved in the water, and points out sea life rather than leaving you to search alone. Some outings have also included underwater photos that were sent afterward, though you should confirm current photo arrangements before relying on this.

A small group makes a noticeable difference. With no more than seven people, the guide can watch the group more closely and answer questions without shouting across a crowded boat. The tradeoff is that the activity is shared, so the pace cannot be tailored completely to one person. If one person wants to keep snorkeling while another wants to rest, the guide has to balance both needs.

Is this suitable for children and less confident swimmers?

The minimum age is six, and children must be accompanied by an adult. Most people can participate if they have basic swimming skills, but this is not a pool lesson or a boat ride where you stay seated throughout.

For children, the sandy Schinias stop is likely to be the easiest success point. The rocky first stop can feel cold, unfamiliar, or intimidating, especially when a child has never used a snorkel mask. Float noodles and shallow water help, but they do not remove the need for confidence in the sea.

I would book this for adventurous children who are comfortable swimming and happy to try new equipment. For a cautious six-year-old, I would discuss expectations clearly before booking. The first stop may be better treated as optional, with the beach stop as the relaxed family highlight.

Adults should also be honest about their ability. One unusually critical account described the trip as more strenuous than expected for a mixed-age group. That is useful advice. The guide can support beginners, but you still need to enter and move through the water. If you want a completely effortless outing, choose a beach-based activity instead.

Weather, water temperature, and comfort

The trip depends on good weather. If poor conditions cause a cancellation, you are offered another date or a full refund. Wind can alter the feel of the speedboat ride and may affect which cove works best for snorkeling.

Water temperature is worth considering. A mid-April outing had cold water and strong wind. Adults found wetsuits helpful, while several children became cold after only a few minutes. Summer should generally feel more comfortable, but the supplied information does not promise a particular water temperature.

Pack a towel, swimwear, and dry clothes. The towel is specifically not supplied, and dry clothing is useful after the final swim. You may also want a simple layer for the boat ride back, since wet skin and wind can make the return feel cooler than expected.

Snacks and drinks are provided. Past trips have included bottled water, tea, juice, biscuits, and fruit such as cherries. These are welcome after time in the water, but they do not replace a full meal. Nea Makri has beachside restaurants, and the area works well for lunch after the excursion.

Getting to Nea Makri from Athens

The stated meeting point is Kanelakis Diving Experiences, Frinis 20, Nea Makri 190 05. The tour information also highlights convenient hotel pickup and drop-off, but the meeting-point details say the activity begins and ends in Nea Makri. I would confirm the exact transport arrangement when you book, especially if you are staying in central Athens.

Nea Makri is not as convenient as a central Athens departure point. One outing required extra effort to get there, but the town’s beaches and restaurants made it worthwhile afterward. If your schedule is tight, allow plenty of time for the trip to and from Nea Makri instead of treating this as a quick add-on between major Athens sights.

The area can make a good half-day escape from the city. After snorkeling, you can stay near the beach for food and a slower afternoon. Some guides have also helped visitors with bus stops or taxi arrangements, but transport help should be viewed as a kindness rather than a guaranteed part of the package.

Is $102.80 good value?

At $102.80 per person, this is not the cheapest way to get into the water. The price makes more sense when you count the small group, speedboat, instructor, snorkeling equipment, wetsuit, refreshments, and access to several coastal locations within four hours.

You are paying for more than a mask rental at a beach. The boat reaches places that are not as simple to visit independently, and the instructor adds both safety support and local knowledge. For a first snorkeling experience, that guidance can be worth the extra cost.

The value is weaker if you are already comfortable snorkeling and only want a quick swim. You might spend less by renting equipment from a beach operator, although you would lose the boat ride, the guide’s explanations, and the chance to visit the two different settings.

The price also works best when you use the whole outing. Stay for the beach stop, enjoy the boat ride, and plan lunch in Nea Makri afterward. That turns a four-hour activity into a satisfying half-day away from central Athens.

Who should book this excursion?

I would choose this trip if you want a personal introduction to Greek coastal snorkeling rather than a large boat party. It suits couples, families with confident swimmers, and small groups who value direct contact with an instructor.

It is especially useful for beginners. Dimitris’s patient approach, equipment help, and explanations make the first step less daunting. The small group also means you can ask questions and get help without feeling lost in a crowd.

I would think twice if you dislike speedboats, get cold easily, have limited swimming ability, or expect tropical-style marine life. The sea can be chilly, the first stop can feel physical, and the creatures may be small and scattered. This is a local Mediterranean snorkeling outing, not a coral reef safari.

Cancellation is free up to 24 hours before the start time. Inside that window, the payment is not refunded and changes are not accepted. Confirmation is sent within 48 hours, subject to availability. Service animals are allowed, public transportation is nearby, and most people can participate if they meet the swimming and age requirements.

My verdict: book it for the guide and the setting

I would book this excursion if you have four hours to spare in Nea Makri and want a calm, personal way to reach the Marathon coast. The guide, small group, and mix of rocky snorkeling with a sandy beach give it more character than a simple equipment rental.

Go in with sensible expectations. Bring a towel, expect some cold water, and understand that snorkeling may require real effort at the first stop. If you do that, the speedboat ride, clear coves, Schinias Bay, and close attention from Dimitris add up to a strong half-day experience at a fair price.
