Proti Island: Snorkeling Boat Tour
The best part of this outing is the WWII shipwreck at Vourlia Beach. Sections of the 40-meter ship sit just below the surface, so you can see the remains without needing scuba gear. Around you, Proti Island is quiet and uninhabited, with clear water and a sandy cove.
I like the choice of a two-stop morning trip or a shorter afternoon outing. I also like the small group, limited to eight people, and the included mask, snorkel, and fins. The main catch is simple: the afternoon tour visits only one site, and there is no guide in the water, so you need to be comfortable snorkeling independently.
Key points to know before booking

- Vourlia Beach is the main attraction: Swim in a calm cove with turquoise water and a WWII shipwreck near the bay entrance.
- Morning and afternoon options differ: The morning trip lasts about four hours and includes two snorkeling locations. The afternoon trip lasts about two hours and includes one.
- The group is kept small: A maximum of eight participants makes it easier to get equipment fitted and move around the boat.
- Wetsuits are optional: You can request a 2.5mm shorty or 5.5mm full wetsuit, a useful choice for longer swims or cooler water.
- This is for swimmers: The activity is not suitable for non-swimmers or people with pre-existing medical conditions.
- Bring your own basics: Pack water, sunscreen, swimwear, and a hat. Snacks are not included.
Reaching Proti Island from Marathopolis

The tour begins at the Scuba Turtles center in Marathopolis, on the west coast of the Peloponnese. Proti Island lies about two nautical miles offshore, close enough for a practical boat outing rather than a full-day expedition.
I appreciate that the crossing takes you to a genuinely quiet setting. Proti is uninhabited, so there are no cafés, shops, roads, or beach facilities waiting at the other end. That gives the trip a peaceful feel, but it also means you need to bring what you require for the time on the water.
Arrive at the stated meeting time, not earlier. The center specifically asks you not to come ahead of schedule because the staff may not yet be ready to welcome you. This is a small operational detail, but it matters when you are planning your morning.
The group limit of eight is one of the strongest practical features. A smaller boat party usually means less confusion when masks and fins are handed out, and it gives you more room to move between the boat and the water. One useful point from the outing itself is that equipment was fitted before departure, though it was not always obvious on the boat which fins and masks belonged to whom. I suggest remembering your gear as soon as it is assigned.

Choosing between the two-hour and four-hour outings

The morning tour lasts about four hours and visits two snorkeling locations around Proti Island. The first listed stop is Vourlia Beach, with about 70 minutes in the water. After returning to the boat, you continue to a second location for roughly another hour of snorkeling.
The afternoon tour lasts about two hours and visits just one location. That makes it a better fit if you have limited time, prefer a lighter outing, or want to focus on the wreck and the cove rather than spend most of the day around the island.
The difference is important enough to affect your booking decision. The morning trip gives you more time in the water and a second setting, but the longer schedule may feel excessive if underwater scenery is not your main interest. The afternoon outing is more focused, but you give up the variety of a second stop.
Based on the available comments about the sites, the wreck is the clear star. One participant found the fish and seabed less interesting than the ship itself and felt the wreck alone would have been enough. That is useful advice, especially if you are choosing between the two durations. If you mainly want to see the ship, the short outing may suit you well. If you enjoy relaxed swimming and comparing two locations, choose the morning departure.
Vourlia Beach and the shipwreck

Vourlia Beach sits in a sheltered cove on Proti Island. Its sand and clear turquoise water create the most scenic part of the trip, and the setting feels far removed from the mainland even though the island is only two nautical miles away.
The wreck lies at the entrance to the bay. It is a 40-meter-long WWII ship, with some sections just below the surface. That shallow position is what makes the site suitable for snorkeling. You can look down through the water and see parts of the structure without specialized equipment or formal scuba training.
I would set your expectations correctly. This is not a technical wreck excursion, and you should not expect to explore every part of the ship. The attraction is the chance to see a piece of wartime history from the surface while swimming in a quiet cove.
The water clarity should help you make the most of the site, but visibility and marine life can vary. The available feedback praises the surroundings and the wreck, while one outing found the fish and seabed fairly ordinary. If you need a busy reef packed with marine life, this may not be your ideal snorkeling trip. If you like the combination of a wreck, clear water, and an uninhabited island, the site has a strong appeal.
You will spend around 70 minutes snorkeling at Vourlia Beach on the morning schedule. That is enough time to look around the wreck, swim near the beach, and return to the boat without having to rush through the stop. Afterward, you head to the second snorkeling area.
What the second snorkeling stop adds

The second location is included on the morning tour and allows about an hour in the water. The details of the site are not specified, so I would treat it as a chance to enjoy another section of Proti Island rather than book the trip for a particular underwater feature there.
This extra stop matters because snorkeling can feel repetitive when you remain in one small area. A second location gives you a change of view and lets you decide how active you want to be after the first swim. You can spend the first stop concentrating on the wreck, then use the second for open-water swimming and fish watching.
Still, the second site may not impress you as much as Vourlia Beach. The strongest praise is aimed at the beautiful surroundings, the wreck, the helpful staff, and the quality of the equipment. One participant who spent two hours in the water felt that was enough, while another preferred the wreck to the general seabed. I would choose the morning trip for extra time and variety, not because the second site is guaranteed to be the highlight.

Equipment, wetsuits, and comfort in the water
Mask, snorkel, and fins are included in the price. The staff fit the masks and fins before the boat heads out, which is important because poorly fitted equipment can turn a pleasant swim into a constant struggle with leaks or loose straps.
You can also request either a 2.5mm shorty wetsuit or a 5.5mm full wetsuit. The thicker suit provides more warmth and coverage, while the shorty is less restrictive and may be enough for people who do not feel the cold easily. A wetsuit can also make longer periods in the water more comfortable.
One participant specifically found the wetsuit very helpful. I would take that as a practical reason to ask about one, particularly if you choose the four-hour morning outing or tend to cool down during extended swims. The available information does not state whether there is an extra charge, so check that point when arranging your equipment.
The boat is also used by people taking part in scuba activities, and one outing shared the boat with a few divers. That does not change the snorkeling plan, but it explains why the operation may serve more than one type of water activity at the same time.
Staff, languages, and the small-group setup

Scuba Turtles provides instruction in English, Greek, and Spanish. The staff are described as kind, welcoming, and helpful, with clear explanations before entering the water. The equipment and facilities also received positive comments.
There is no guide on the water, so do not expect someone to lead you from one underwater feature to another or provide a marine-life talk while you swim. You receive the boat transport and equipment, but you remain responsible for following the safety instructions and staying within your ability.
That setup suits confident swimmers who like freedom. It is less suitable if you want close supervision or feel uneasy in open water. The activity is expressly not suitable for non-swimmers or people with pre-existing medical conditions.
The small group helps balance the lack of an in-water guide. With no more than eight participants, it should be easier to hear the instructions, ask questions before leaving, and keep track of your personal gear. I would still pay attention when equipment is distributed, since it was not always easy to tell whose mask or fins were whose once everyone was on the boat.
Price and what the $58 covers

At $58 per person, this tour offers reasonable value if you want a boat ride, access to Proti Island, snorkeling equipment, and time at the wreck without arranging each part separately. The morning option gives you about four hours, two water stops, and a visit to Vourlia Beach.
The value is weaker if you are interested only in the shipwreck. Since the afternoon tour visits one location and lasts about two hours, it is the more efficient choice for a focused outing. You are paying for a short boat trip and a chance to snorkel at a notable shallow wreck, rather than for a full day of activities or a guided marine lesson.
Snacks are not included, so bring water and anything else you need for the time out. The island is uninhabited, and you should not expect to buy food or drinks there. Alcohol, smoking, fishing, feeding animals, and littering are not allowed.
Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later. Those terms are useful if your Peloponnese plans may shift, though you still need to check the available start times before choosing a morning or afternoon slot.
Who will enjoy this trip most
I would recommend the tour to confident swimmers, couples, friends, and small groups who want a simple half-day on the water. It is especially appealing if you like unusual swimming spots and prefer a quiet island to a developed beach.
The morning tour is the better choice for anyone who enjoys spending time in the water and wants two locations. You will have room to slow down, look around the wreck, and swim at the second stop rather than treating the outing as a quick photo stop.
The afternoon trip suits people with a tighter schedule or those who want the main attraction without committing four hours. It also makes sense if you know that a long period of snorkeling is not your style.
I would not choose this activity if you want a highly guided underwater tour, a lesson in marine biology, or guaranteed abundant sea life. The experience is centered on clear water, a quiet island, and a shallow historic wreck. Its charm comes from the setting and the freedom to swim, not from a packed program.
Practical packing advice for Proti Island
Bring swimwear, sunscreen, a hat, and enough water. Since snacks are not supplied and Proti is uninhabited, pack any small food item you need before setting out, as long as it fits the operator’s rules and does not create litter.
Wear sunscreen before boarding, then reapply as appropriate. You will be exposed to sun around the boat and while swimming, even if the cove provides some shelter. Keep your belongings organized, and remember which mask and fins were fitted to you.
Do not bring pets, fishing gear, alcohol, or drugs. Smoking is not allowed, and you must not feed the fish or leave rubbish behind. These rules protect the calm setting and keep the boat trip straightforward.
The tour has a rating of 4.8 out of 5 from nine ratings, with especially strong praise for the friendly staff, professional operation, good equipment, beautiful sites, and comfortable pace. The more cautious point is that the underwater scenery beyond the wreck may feel modest. I would book with that distinction in mind.
Should you book the Proti Island snorkeling tour?
Book it if the idea of swimming above a shallow WWII wreck in a quiet island cove appeals to you. The small group, included equipment, optional wetsuits, and choice of duration make it easy to fit into a Peloponnese itinerary.
Choose the morning tour for two snorkeling locations and a slower half-day. Choose the afternoon option if you mainly want Vourlia Beach and the wreck. If your priority is abundant marine life or close underwater guiding, look for a different activity. For a capable swimmer who values scenery, a historic wreck, and a relaxed boat outing, this is a well-priced way to see a less developed side of the coast.
