Review · SEA CAVE AND GROTTO BOAT TOURS
From Vis: Speedboat tour – Vis, Biševo & Blue Cave (shared)
The best thing about this small-group speedboat tour is its range. In about six and a half hours, you see Vis from the water, visit Biševo’s famous Blue Cave, swim at several coves, and enter a former military tunnel. Local skipper Luka gives the day a personal feel, adding island stories and adjusting the timing to avoid the worst crowds.
I especially like the priority Blue Cave entry and the long stops for swimming. Stiniva gets about an hour, and the boat also reaches places larger vessels cannot. The catch is simple: this is a fast boat, so expect wind, spray, and a lively ride. It is not suitable for pregnant women or people with back problems.
Key points at a glance

- Priority access to the Blue Cave: The local operator uses a fast-entry card, helping you avoid the long waits common at this popular stop.
- A proper swimming day: You get time at Pritišćina, Stiniva, Green Cave, Budikovac, and sandy Smokova beach.
- Local guidance from Luka: He shares facts about Vis, its military past, rock formations, sea life, and personal island memories.
- Small boat, broad route: The RIB can reach narrow coves, a submarine tunnel, and beaches that larger boats may skip.
- Cave tickets cost extra: Blue Cave and Green Cave admission is separate, so budget for those charges and carry cash.
- Bring your own lunch: Water is included, but the long route is built around swimming stops rather than a full restaurant meal.
Why this Vis boat tour covers so much

Vis is best appreciated from the sea. From the boat, steep rock faces, sheltered bays, old military sites, and small islands line up in a single day. You do not spend the morning waiting for road transfers or hiking down to every beach. You step off the boat straight into clear water.
The tour starts at 8 in the morning from Vis town marina. Pickup is available anywhere inside the Vis marina, and it may be possible to collect you farther along the route if that fits the day’s plan. Look for the approximately 7.5-meter RIB with NEMO stickers.
The listed price is $117 per person. For a 390-minute outing, that is fair value if you want several swims and the Blue Cave in one booking. The price includes the skipper, fuel, bottled water, snorkeling masks and snorkels, insurance, an onboard refrigerator, and marina pickup and return.
It does not include entry to the Blue Cave or Green Cave. That separate payment gives you the choice to skip either cave and remain on the boat, but most people will want to budget for both. The Blue Cave ticket is bought by the skipper using the operator’s priority card, while Green Cave admission is paid to the cave team. Carry cash, since one practical reminder sent to participants specifically advises it.

The Blue Cave first, before the crowds build

The first major stop is the Blue Cave on Biševo, reached after roughly 30 minutes by speedboat. The cave is famous for the blue light that fills the interior when sunlight enters through an underwater opening. The visit inside lasts about 20 minutes, and the Blue Cave crew conducts the actual cave ride.
The smart part of doing this stop early is timing. Blue Cave queues can eat up a large part of a day, especially in high season. As a carrier from Vis, this tour uses a fast-entry card, so the skipper can buy the tickets and move the group through more quickly. Several participants describe getting in and out in around 30 minutes, including the waiting and cave visit.
That advantage matters. You are not paying only for a famous photograph. You are also protecting the rest of your day for swimming and smaller sites. Still, keep expectations sensible. The cave is a short, tightly managed visit, not a private exploration. You cannot swim inside the Blue Cave, and the time there depends on sea conditions and the official cave operation.
The boat may be one of two listed models, a Bat Arctic 745 with a Suzuki 250-horsepower outboard or a RIS Marine Scorpio 300 with an inboard engine. Both are equipped with a sun canopy, sun deck, and sea ladder. The exact boat can vary, but the setup is designed for quick movement between islands and easy water access.
Military tunnels and the quieter side of Vis

After the Blue Cave, the route turns back toward Vis and its less polished side. A stop at a former military tunnel in Parja Bay gives you a look at the island’s strategic past. Vis was once heavily controlled for military reasons, and this old coastal infrastructure feels very different from the postcard beaches.
The tour also includes a secret or lesser-known stop for about 30 minutes, along with scenic passes and photo points. The exact order can change. That flexibility is useful because Luka adjusts the route for weather, sea conditions, and crowd levels. One particularly strong feature of his guiding is knowing when a bay will be at its best, not merely following a fixed clock.
You should not expect a long guided museum visit at the military site. This is a boat-based look at the tunnel and surrounding coast. The value is in seeing how Vis combines natural shelter with military history, then moving on before the day becomes repetitive.
Pritišćina is made for the first swim

Pritišćina is scheduled for about 45 minutes of free time. This is where the day shifts from sightseeing to swimming. You can use the supplied masks and snorkels to look for marine life, climb back aboard for water, or simply sit on the boat and enjoy the cove.
The snorkeling equipment includes masks and snorkels, but not fins. If you like to swim farther from the boat, bring your own fins. A sea ladder makes getting back aboard easier, though you should still be comfortable entering open water from a boat.
Pritišćina is one of the places where the small boat matters. The tour can stop in coves and narrow coastal spaces that are less practical for large group boats. Do not expect an organized beach club or a long list of facilities. That is part of the appeal, but it also means you should bring sun protection and anything else you need for a swim.

Stiniva Cove gives you the longest beach stop

Stiniva is the emotional center of the route for many people. Its narrow entrance opens into a sheltered cove with a beach backed by steep stone walls. From land, reaching it involves a demanding hike down and back up. By boat, you arrive directly at the water, which is a major practical advantage.
The tour allows at least one hour here. You can swim, snorkel, sunbathe, have coffee or a beer at the beach bar, or take photos from the water. That hour is long enough to enjoy the setting instead of treating Stiniva as a rushed photo stop.
The beach is not large, so do not expect solitude in the middle of summer. The boat approach avoids the hike, but it does not make the cove private. The shore can feel busy, and the water around the boat may have regular movement from other craft.
Still, Stiniva is exactly the sort of place where a planned hour pays off. You get a famous site plus time to use it. If you want to swim, bring your suit under your clothes and keep your towel close. The tour is built around repeated water stops, so changing facilities are not the main feature.
Green Cave on Ravnik lets you swim inside

The Green Cave, on the small islet of Ravnik, offers a different experience from the Blue Cave. Here, you can enter by boat or swim into the cave, depending on the conditions and your comfort in the water. The stop lasts about 30 minutes and includes time for photos, sightseeing, snorkeling, and wildlife viewing.
Admission is separate. After the skipper moors near the cave, anyone entering pays the Green Cave team directly. You can also stay aboard if you prefer not to pay or do not want to swim into the opening.
This stop suits confident swimmers best. The cave is not simply a viewpoint from a boat. The chance to enter the water makes it more active, but it also means you should take the safety briefing seriously and follow the skipper’s instructions. Conditions can change, and the boat’s schedule must continue.
Budikovac brings a calmer lagoon stop

The Budikovac Blue Lagoon follows the Green Cave, only about five minutes away by boat. You get around 45 minutes here for swimming, snorkeling, and a break. The sheltered water makes this one of the more relaxed stops on the route.
The lagoon is a good place to slow the day down. By this point, you have already seen the Blue Cave and Stiniva, so Budikovac gives you room to float, look into the clear water, and enjoy the boat without another major sightseeing demand.
The phrase Blue Lagoon can make a place sound completely untouched, but this is still part of a popular island route. In peak season, other boats may be nearby. The benefit is not guaranteed solitude. It is having a planned swim in a sheltered setting with equipment and water already on board.
Smokova beach ends the day on sand

The final substantial stop is Vela Smokova, a sandy beach where you get about 45 minutes for swimming, snorkeling, photos, and rest. Sand is a welcome change after the rocky coves and stone beaches found around much of the coast.
Smokova also has a personal connection for Luka, who grew up near this beach. That detail gives the final stop more meaning than another generic swim. You can ask about the area and hear how the coast looked before it became a regular stop on boat routes.
For many people, this is the easiest place to simply enjoy the water. You do not need to turn every stop into an activity. Sit on the sand, use the shade from the boat’s canopy when needed, or take one last swim before the return to Vis.
After Smokova, the boat passes a viewpoint for about five minutes, then returns toward Parja and the military tunnel area before reaching Vis marina. The listed return sequence includes another 25-minute visit at Parja, though the captain may adjust the order to suit the day.
What the boat ride feels like

This is a speedboat excursion, not a slow coastal cruise. The journey between stops ranges from about five to 30 minutes. That lets you cover a lot of water, but the ride can feel bumpy when the sea is rough.
The boats have a bimini for shade, a sun deck, and a sea ladder. The small-group setup is usually capped at around 10 people, and some departures have had only seven passengers. On a busy date, the operator may use a second boat to keep the group comfortable.
That group size is one of the tour’s strongest practical features. Luka can speak with people directly, help with baggage, and make small adjustments. One participant even described being transferred to a beach in a small dinghy instead of swimming all the way in. That kind of flexibility is useful, but it depends on the conditions and the group.
Bring a towel, sunglasses, a hat, sunscreen, and a waterproof phone pouch. The boat has a refrigerator and bottled water, but lunch is not listed as included. Pack something to eat, especially if you prefer not to rely on the coffee and beer stop at Stiniva.
Who should book this tour
I would choose this outing if you have only a few days on Vis and want to see the island’s main coastal sights without arranging separate boat trips. It suits active couples, families with older children, and small groups that want regular swims rather than a full day of sitting on a boat.
It is also a strong choice for anyone who wants Stiniva without the land hike. The route includes several chances to snorkel, though the supplied gear has no fins, and the water stops require basic comfort around a boat.
I would think twice if you have back trouble, are pregnant, or dislike fast boat travel. You should also skip it if your ideal island day means one quiet beach and no schedule. This route is well paced, but it is still a full itinerary with many stops.
The guide makes a real difference. Luka’s local background, personal stories, knowledge of the coast, and attention to timing are repeatedly singled out. He has also contacted people before departure when a date looked likely to have poor weather, suggesting a practical approach rather than a rigid one.
Is the $117 price worth it?
At $117, the tour gives you a long day on the water, fuel, equipment, a professional skipper, pickup and return inside the marina, and access to a route that would be difficult to reproduce independently. The priority Blue Cave entry is especially valuable during the summer rush.
You still need to add cave tickets, and that makes the final cost higher than the headline price. Even so, the price compares well with the time covered and the number of places visited. You are paying for transport between islands, local route planning, and a small boat that can reach narrow bays.
The value drops if you do not plan to swim or if you want a slow, private charter. For most people seeking a broad introduction to Vis by sea, the combination of Blue Cave, Stiniva, Green Cave, Budikovac, Smokova, and the military tunnel makes the cost reasonable.
Should you book it?
Book this tour if you want the full coastal sampler of Vis in one day, especially with a local skipper who can manage the timing. The priority Blue Cave entry, direct boat access to Stiniva, and long swimming stops are the strongest reasons to choose it.
Skip it if fast boats bother you, you need a very gentle ride, or you want to spend the day in one place. For an active first look at Vis and nearby Biševo, this is a well-rounded choice. Just bring lunch, cash for the caves, sun protection, and a willingness to get wet.
