Proti Island: Snorkeling Boat Tour
Clear water, quiet coves, and a shipwreck make this Proti Island boat trip a fine choice for a half-day on Greece’s western Peloponnese coast. From Marathopolis, you head about 2 nautical miles offshore to an uninhabited island with calm water, a sandy cove, and fish-filled snorkeling sites.
I like the small group of up to eight people, which keeps the outing personal and easier to manage. I also like that masks, snorkels, and fins are included, with shorty and full wetsuits available if the water feels cool. The main caution is simple: the afternoon option visits only one snorkeling site, and the seafloor may feel modest if the wreck is your only goal.
The tour is run by Scuba Turtles, with instruction available in English, Greek, and Spanish. Recent feedback praises the friendly staff, good equipment, helpful explanations, and comfortable pace. One useful tip from the equipment experience: make sure you can identify your mask and fins once everyone is back on the boat.
Key points to know before you book

- Vourlia Beach is the main setting: You snorkel in a quiet cove with clear turquoise water and a sandy beach on uninhabited Proti Island.
- The WWII wreck is the star attraction: A 40-meter ship lies at the entrance to the bay, with parts just below the surface.
- Morning gives you two sites: The four-hour morning trip includes about 70 minutes at Vourlia Beach and another snorkeling stop of about one hour.
- Afternoon is shorter: The two-hour option visits only one location, so check the departure details before booking.
- Equipment is included: Mask, snorkel, and fins come with the tour, while 2.5-millimeter shorty and 5.5-millimeter full wetsuits are optional.
- This is for swimmers: Non-swimmers and people with pre-existing medical conditions should not book this activity.
Why Proti Island makes a good snorkeling outing

Proti Island sits just off the west coast of the Peloponnese, roughly 2 nautical miles from Marathopolis. Its uninhabited character is a big part of the appeal. You are not heading to a developed beach resort with rows of facilities. You are going to a quiet island cove where the sea, sand, and underwater sites provide most of the entertainment.
That simplicity suits a snorkeling trip. You spend less time looking for something to do and more time in the water. The boat carries you from the Scuba Turtles Dive Center to two locations on the morning trip, so you get some variety without turning the outing into a long, tiring expedition.
I especially like the scale of this experience. With no more than eight participants, the boat should feel more manageable than a large group cruise. That matters when equipment needs adjusting or when you want clear instructions before entering the water. The staff can provide guidance in English, Greek, or Spanish, which is useful for a water activity where safety instructions need to be understood quickly.
The trip also works well for people who want a structured outing but not a full-day commitment. The morning version lasts four hours. The afternoon version takes about two hours. You can fit either into a larger day around Marathopolis, but the shorter option comes with a clear tradeoff: only one snorkeling site.

Setting out from the Scuba Turtles Dive Center

Your meeting point is the Scuba Turtles Dive Center. Arrive at the stated meeting time, not early, because the center may not be ready to receive you before then. That small timing detail is worth taking seriously. A dive center has equipment to organize and a boat schedule to prepare, so arriving at the right time keeps the start orderly.
You should arrive wearing your swimwear and bring a hat, sunscreen, and water. Snacks are not included, so bring something if you need food during or after the outing. Alcohol, smoking, fishing, littering, and feeding animals are not allowed.
At the center, you receive your mask, snorkel, and fins. A proper fit matters more than it may seem. A leaking mask can ruin a calm snorkeling session, while poorly fitted fins can make swimming tiring. Take a moment to check the seal around your mask and make sure the fins feel secure.
The boat carries a maximum of eight participants, creating a more relaxed setup for equipment checks and boarding. The available reviews describe the staff as kind, welcoming, and professional. They also note that explanations were clear and that the pace felt comfortable rather than rushed.
One practical equipment point deserves attention. On the boat, several sets of fins and masks may look alike, so remember which gear belongs to you. Marking the position of your equipment mentally before getting into the water can save a little confusion later.
Vourlia Beach and the 70-minute snorkeling stop

The first major stop is Vourlia Beach, a sandy stretch tucked into a quiet cove. The water here is described as crystal clear and turquoise, giving you good conditions for looking below the surface. Since Proti Island is uninhabited, the setting feels peaceful and removed from the mainland.
The planned snorkeling period at Vourlia lasts about 70 minutes. That gives you enough time to settle into the water, swim at an easy pace, and look around without feeling that you have only a few minutes before returning to the boat.
The cove is the kind of place where the setting is as important as the marine life. You can look toward the beach, the rocky edges of the bay, and the clear water around you. The trip is not presented as a specialist marine biology excursion, so the value comes from the combination of accessible snorkeling, open sea, and a secluded island stop.
Expectations matter here. One participant found the wreck more memorable than the fish and seafloor, describing the underwater scenery away from the ship as somewhat ordinary. That does not make Vourlia a poor stop, but it does suggest that experienced snorkelers seeking dense marine life may find the natural underwater scenery fairly modest.
The water itself is a major strength. Several comments praise the beauty of the sites and the quality of the snorkeling equipment. The pace also received positive feedback, which matters if you prefer time to look around rather than being hurried from one point to the next.
The WWII shipwreck just below the surface
The wreck is located at the entrance to Vourlia Bay. It is a 40-meter-long WWII ship, with parts of the wreck sitting just below the surface. That shallow position makes it suitable for snorkeling rather than requiring scuba equipment.
For many people, this is the clearest reason to choose the tour. A wreck gives the outing a focal point. Instead of simply looking at the seafloor, you have a recognizable object to explore, with the shape and story of a vessel visible beneath the water.
You should not expect a fully intact ship sitting in deep water. The information provided describes some sections as just below the surface, making them accessible to snorkelers. The appeal is the chance to see a wartime wreck from above and around its shallow remains, not a technical wreck exploration.
One participant said the shipwreck was the highlight and would have been enough on its own. That is useful advice if you are choosing between the two tour lengths. If the wreck is your priority, ask which option includes it and how much time you will spend there. The afternoon trip visits one location, so it may suit someone who wants a shorter outing centered on the main site.
The wreck also adds a bit of historical interest without turning the tour into a formal history lesson. You see a physical reminder of the Second World War in a quiet Greek cove. That contrast, a warship beneath clear water beside a peaceful beach, gives the stop more character than a standard swim break.

The second snorkeling site on the morning trip

After Vourlia Beach and the wreck, the morning boat continues to a second snorkeling location. This stop lasts about one hour. The exact site is not specified, so you should think of it as a second chance to swim and see another part of Proti Island rather than a guaranteed particular attraction.
That extra stop is the main reason to choose the four-hour morning option. It gives you more time in the water and a change of scenery. If you enjoy snorkeling for its own sake, that added hour can make the trip feel worthwhile. You also get more time to use the equipment, swim with fish, and enjoy the island from the water.
The tradeoff is time. Four hours is still a manageable morning, but it takes up more of your day than the afternoon version. If you have limited time in the Peloponnese or want a quick activity before dinner, the shorter trip may be the better fit.
A past participant who spent two hours in the water found that amount sufficient, while another enjoyed the variety of the different sites. These comments point to a personal choice: pick the morning trip for variety, or the afternoon trip for a simpler, shorter experience.
Equipment, wetsuits, and comfort in the water

The tour includes a mask, snorkel, and fins. That is a real part of the value because you do not need to rent basic snorkeling gear separately or pack your own set. Recent feedback describes the gear as good quality overall, though you should still check the fit before leaving the center.
Two wetsuit options are available at extra or optional status: a 2.5-millimeter shorty and a 5.5-millimeter full wetsuit. The thinner shorty gives more coverage while keeping your arms and legs freer. The thicker full suit offers more warmth and protection.
One participant specifically found the wetsuit very helpful. Water temperature can vary by season and personal comfort, so this option matters if you tend to feel cold during extended swims. It may also make the morning trip more comfortable because you spend longer in the water.
You should bring sunscreen, but remember that the tour rules prohibit littering and feeding animals. Use sun protection responsibly and keep all packaging with you until it can be disposed of properly.
Is $58 a fair price?
At $58 per person, the tour sits in a reasonable range for a small-group boat outing that includes snorkeling equipment and access to two offshore locations on the morning version. You are paying for the boat ride to Proti Island, the use of gear, a visit to Vourlia Beach, and the chance to see a shallow WWII wreck.
The value is strongest if you choose the four-hour morning trip. You get two snorkeling locations and more time around the island. The small group also adds practical value, since eight people is a much more comfortable number for a water activity than a crowded boat.
The afternoon option deserves a closer look. It costs the same stated price while lasting about two hours and visiting only one location. That can still be worthwhile if your main aim is a short swim and the wreck, but you should not book the afternoon trip expecting the full two-stop experience.
Snacks are not included, so plan accordingly. You also need to arrange your own way to the Scuba Turtles Dive Center, since no separate transportation service is listed. The ability to reserve now and pay later, plus free cancellation up to 24 hours before departure, gives you some useful flexibility when weather or plans are uncertain.
Who will enjoy this trip most

I would recommend this outing to confident swimmers who enjoy clear water, quiet beaches, and a manageable boat trip. It suits couples, small groups of friends, and solo participants who prefer a personal-scale activity.
It is also a good match if you want to try snorkeling without buying or carrying equipment. The included mask, snorkel, and fins remove one common hassle, while the optional wetsuits help with comfort.
The tour may disappoint you if you want a major reef system, a large variety of marine life, or a full historical presentation about the wreck. The natural seafloor away from the ship may feel fairly plain, and the emphasis is on swimming and viewing rather than formal instruction.
Non-swimmers should not book. The experience also is not suitable for people with pre-existing medical conditions, so check your own health needs before reserving. The staff can explain the activity in three languages, but the physical demands remain the same.
Should you book the Proti Island snorkeling tour?
Book it if you want a small-group boat outing with clear water, an uninhabited island, and an unusual shallow WWII wreck. I particularly like the morning option because the second snorkeling site gives you more for the $58 price and makes the boat ride feel properly worthwhile.
Choose the afternoon trip only if you prefer a shorter schedule or mainly want the wreck and one swim stop. Bring water, sunscreen, a hat, and swimwear, and arrive at the dive center at the assigned time. If you are a comfortable swimmer with realistic expectations about the marine life, this is a friendly, well-organized way to spend part of a day off the Peloponnese coast.
