Chalkidiki: Blue Lagoon & Ammouliani Island Cruise & Lunch

The best part of this six-hour cruise is the contrast between its two swimming stops: first, a boat-based swim in the clear, shallow waters near Diaporos, then a shore stop at Ammouliani’s beautiful Alikes Beach. Along the way, you look through the glass-bottom keel at yellow corals and watch the Sithonia coastline slide past.

I like the traditional souvlaki lunch, which gives the outing a proper Greek flavor rather than serving only packaged food. I also like the generous swimming time, with about 1.5 hours at each main stop. The main catch is simple: the first swim requires you to jump from the boat into water about two meters deep, so confident swimmers get the most from it.

The cruise is family-friendly, but it can be lively and noisy, especially with a DJ and many children aboard. Strong winds may also force the boat to skip Diaporos and spend more time at Ammouliani instead.

Key points to know before booking

• The first swim is from the boat: You must be comfortable entering water about two meters deep. A beach entry is not provided at Diaporos.
• Ammouliani offers an easier shore stop: The boat anchors at the lagoon port, giving you access to Alikes Beach and its beach bars.
• Lunch is Greek and light: Expect pork souvlaki, Greek salad, tzatziki, bread, wine, and children’s beverages.
• The boat has more than a glass floor: You also get a DJ, a VIP deck, seats on several levels, and drinks and snacks for purchase.
• Weather can change the plan: Strong winds may cancel the Diaporos stop and replace it with time at Ammouliani’s village port.
• Arrive early at Ouranoupoli: The port is by the Tower of Prosforion, and you should arrive about 30 minutes before departure.

This cruise from Eirinikos Glassbottom Cruises is a good way to see several corners of Halkidiki without arranging ferries, taxis, and separate beach visits. For $45.17 per person, you get six hours at sea, two planned swimming stops, a buffet lunch, safety equipment, and entertainment.

That price is particularly fair if you plan to spend the day swimming. A similar outing would require transport to the coast, food, and beach spending on your own. The cost does not cover hotel pickup, extra drinks, snacks, or anything you buy at the beach bars, so keep a little cash or a card available for those extras.

The boat leaves from the main port of Ouranoupoli, beside the Tower of Prosforion. Parking is available on the right as you enter the village. Boarding begins 45 to 30 minutes before the stated 11:00 start, and arriving 30 minutes early is the sensible choice. It gives you time to find the boat, choose a seat, and settle in before the port gets busy.

The exact starting time can vary, so check availability when booking. The activity finishes back at the same port in the evening.

The cruise starts with a look below the boat. Its glass-bottom section lets you see the yellow corals beneath the keel as you pass over one of the area’s best-known reefs. This is not a full snorkeling session, but it adds something special to the first stretch of the trip.

I like this early portion because it gives you a reason to watch the water even before the swimming begins. Children in particular may enjoy looking down for fish and coral, while adults get a quick introduction to the sea around Ouranoupoli.

The boat then heads toward Sithonia, the second peninsula of Halkidiki, passing the beaches around Vourvourou and Diaporos. Keep your camera ready during this section. The views are one of the main rewards of the cruise, with pale beaches and clear water appearing from the deck as the boat moves along the coast.

The trip from Ouranoupoli to the swimming area takes time. One practical note from the experience is that some of the day can be spent sailing to Sithonia and back, leaving less than four hours for swimming, lunch, and the beach stops on certain schedules. If you want a quick transfer and maximum time on land, this is not the right format. If you enjoy being on a boat, the sailing is part of the outing.

The first major stop is in the Blue Lagoon area near Diaporos Island. The boat anchors in clear water about two meters deep, and you get roughly 1.5 hours to swim.

The water is the star here. It is turquoise, clean-looking, and calm enough for jumping from the boat when conditions are suitable. You may also bring your own snorkeling equipment and a personal swimming vest if you prefer extra support.

This stop needs careful planning. The ship’s life vests are for emergencies and are not permitted for ordinary swimming. You should know how to swim before entering the water. If you are not a confident swimmer, you can stay aboard and enjoy a cocktail from the VIP deck instead. That option matters for mixed groups, since strong swimmers can use the water while less confident family members remain comfortable on deck.

You do not swim straight onto a sandy beach at this first stop. The boat is anchored away from shore, so you may need to swim back and forth in open water. One useful extra is a waterproof bag if you plan to swim toward shore with your phone, wallet, or other belongings. Beach shoes are also worth packing because the shore can be rocky or covered with seaweed.

This is a good place to bring your own mask, snorkel, and towel. The boat provides safety equipment, but personal snorkeling gear gives you more freedom and avoids depending on what is available for shared use.

After the first swim, lunch is served aboard. The buffet includes traditional pork souvlaki, Greek salad, tzatziki, and bread. Wine is included for adults, and beverages are available for children.

The meal is best described as light rather than lavish. It is enough to restore your energy after swimming, especially if you eat a solid breakfast, but I would not treat it as the only food you need for the day. Extra snacks are not included, though you can buy packaged snacks and drinks on the boat. Bringing a few personal snacks is a sensible move for children or anyone who gets hungry between stops.

The food works because it suits the setting. Souvlaki, salad, and tzatziki are easy to serve to a group, and the meal feels connected to Greece rather than like generic excursion catering. Vegetarian food can be prepared, but you need to request it at least one day ahead. Do not wait until boarding, particularly if you do not eat pork or meat.

The boat has enough seating for the group, with different areas offering different moods. The upper or front deck is the better choice if you want more air and a clearer view. The lower areas may be more convenient for lunch and shade, but the cruise can become loud when many children are aboard.

The second main stop is Alikes Beach on Ammouliani. Here the boat anchors at the lagoon port, so you can reach the beach more easily than at Diaporos. You have another 1.5 hours for swimming, walking around, or settling into one of the beach bars with a cocktail.

This stop is likely to suit a wider range of people. Confident swimmers can head straight into the water, while those who prefer dry land can spend time at the beach or sit at a bar. The beach itself is one of the prettiest parts of the day, with clear water and a more conventional seaside setting than the boat-only swim at Diaporos.

You may want an umbrella if you do not plan to spend the entire stop at a beach bar. Shade is not guaranteed as part of the excursion, and an hour and a half in full sun can feel long after a morning on the water.

Ammouliani is also the most weather-sensitive part of the plan. If strong winds make the usual route unsafe, the boat may skip Diaporos and stop at the port of Ammouliani’s central village instead. You could then get more swimming time at Ammouliani, but you would miss the Blue Lagoon stop, which is a key reason many people choose this cruise. Weather decisions are made for safety, but you should understand this possibility before paying.

This is not a quiet sightseeing boat. A DJ plays onboard, and the VIP deck provides a place to sit with a cocktail and enjoy the music. The atmosphere can be cheerful and energetic, especially on a sunny day with children and families aboard.

I would choose your seat early. The top or front deck tends to offer cleaner air, better views, and some distance from the loudest family activity. If you want shade, easier access to lunch, or a calmer place to watch the water, look around before the boat leaves and settle in early.

Drinks and packaged snacks are available for purchase. The selection includes mostly savory snacks with some sweet choices, according to the onboard setup described for the cruise. These extras are not part of the ticket price, so include them in your budget if you expect to buy refreshments throughout the day.

The DJ and VIP deck may be a plus for a family group with older children or anyone who wants more than a passive boat ride. It may be less appealing if your ideal day is a silent sail with only the sound of the sea. The cruise aims for fun, not solitude.

Pack lightly, but bring the things you will use repeatedly. You should have swimwear, a towel, sunscreen, and snacks. A waterproof pouch or bag is useful during the first stop, particularly if you swim away from the boat.

I would add beach shoes because the shoreline may be rocky or have seaweed. Bring your own snorkeling mask and swimming vest if you use them. The boat’s emergency life vests are not intended for swimming.

Sunscreen needs regular attention. You will be exposed on deck during the sailing portions, at the swim stops, and on Ammouliani. A hat can also help, though you should keep it secure in the wind.

If you want to enjoy the beach bar at Alikes, bring money for a cocktail or other purchase. The ticket includes lunch, wine, and children’s beverages, but not extra food or drinks.

This outing suits families, couples, and groups who want a full day by the sea without managing their own transport. It is especially good for people who value swimming time and pretty coastal views more than formal sightseeing.

It also works well for a mixed group. Confident swimmers can jump from the boat at Diaporos, while others can stay on the VIP deck. At Ammouliani, nearly everyone gets a more accessible beach stop.

You should think twice if you dislike crowds, loud music, or long stretches on a boat. Children are common, and the atmosphere can become noisy. The cruise is also a weaker choice for anyone who cannot swim and wants two easy beach entries, since the first stop is specifically a boat swim.

The tour is conducted in English and Greek, with an audio guide in both languages. The host or greeter also speaks English and Greek. Cancellation is flexible up to 24 hours before departure, and you can reserve now and pay later, which helps if your Halkidiki plans depend on weather.

For six hours, the fare covers a lot: the glass-bottom boat, two swimming areas, a Greek BBQ buffet, wine, children’s beverages, safety equipment, and music. The included meal is modest, but it is practical and tasty enough for a day in the sun.

The real value comes from access. You reach Diaporos, Vourvourou, Sithonia, and Ammouliani in one outing, with no need to arrange separate boat hire or beach transport. The price becomes less attractive only if wind changes the route and you miss Diaporos, or if you spend much of the day wishing for a quieter boat.

The experience receives a 4.6 rating from 269 ratings, which fits the overall picture: strong organization, friendly staff, tidy boat, good water, and a lively atmosphere, balanced by a light lunch, noise, and weather-dependent stops.

Book it if you want a sociable day on the water with clear swimming spots, a Greek lunch, island scenery, and plenty of time to play in the sea. It is a particularly good pick for families and groups with at least some confident swimmers.

Skip it if you want a peaceful sailing trip, guaranteed access to Diaporos, or a substantial lunch. If you do book, arrive early for a good seat, request vegetarian food at least a day ahead, bring beach shoes and a waterproof bag, and check the wind forecast before setting out.
