Boat Trip: Grotta del Fico, Cala Mariolu, Gabbiani & Biriala
Book on Viator →Operated by Explorando Supramonte · Bookable on Viator
If you like sea views and real local know-how, this boat day delivers. What makes it special is the Grotta del Fico part: you get the cave tickets included, and your time inside comes with a guided visit featuring rock formations, underground rivers, and sea siphons. Add 100% local guidance and you’ve got more than just a sun-and-splash itinerary.
Two things I especially like are the early start for a calmer route and the pacing that keeps you from feeling yanked around. The guide (Francesco is one of the names you might meet) also focuses on timing so you reach key stops early when possible. One thing to plan for: the itinerary can shift day to day under August 2025 visitor-flow rules, so stops besides Cala Mariolu can depend on what spots the municipality assigns that day.

Key Highlights You Should Know Before Booking

- Grotta del Fico tickets included: one of the very few trips with guaranteed cave admission as part of the tour.
- Early 8:30 departure helps: you’re on the water before many crowds settle in.
- Cala Mariolu is always guaranteed: the beach stop won’t be cut, even when other stops change.
- Other beach stops depend on daily municipality spots: Cala dei Gabbiani, Biriala, and Sisine are subject to availability.
- Swim stops at anchor are short and sweet: you’ll get quick dips at Piscine di Venere and Cala Goloritze.
- Small group size (max 12): easier movement and a calmer feel on a long day.
Why This Baunei Coast Boat Day Feels Worth It

This is the kind of Sardinia day that stays simple and effective: boat ride along the coast, then multiple set pieces where you actually get time in the water or on a beach, plus a cave visit that isn’t just a drive-by. The cave is a big deal here because you’re not scrambling for separate entry. When you’re paying for a boat tour, that kind of included access matters.
You also get a guided experience rather than only being dropped off. The cave portion is guided, and the rest of the day is framed with information about points of interest as you go. If you care about understanding what you’re seeing, it’s a more satisfying way to do the coast than a self-guided boat hop.
The raft-style boat also changes the feel. It’s not about luxury or quiet captions. It’s about getting you close to the shoreline for the stops that make this coast famous.

August 2025 Updates: What’s Guaranteed vs What Can Change

There’s a real-world rule behind the scenes, and it affects your expectations. Due to a new ordinance from the Municipality of Baunei for visitor flow management, the itinerary can change daily.
Here’s what stays the same:
- Cala Mariolu is always guaranteed.
Here’s what can vary depending on availability assigned that day:
- Cala dei Gabbiani
- Cala Biriala
- Cala Sisine
- Other beach stops may be substituted depending on daily assigned spots.
This is not a bait-and-switch situation. It’s how the operator is responding to crowd levels and access control. You’ll still get the core rhythm of the day—boat stops plus swim time—but you should be mentally flexible on which exact beaches you’ll land at, besides Cala Mariolu.
Getting On Board in Santa Maria Navarrese (and How Timing Helps)
You start at 8:30 am at Explorando Supramonte, Porto turistico, 08040 Santa Maria Navarrese (NU), Italy, and you return to the same meeting point at the end.
A few practical points make this more comfortable than it sounds:
- Mobile ticket: less fuss when you arrive.
- Max 12 travelers: the group stays small enough that boarding and movement feel manageable.
- Early start: you’re on the water before the day gets loud. One of the best tips I can give is to treat the early departure as part of the value, not just a schedule inconvenience.
The guide’s pacing also matters. In particular, you’ll likely get better beach time when you reach a stop early, and Francesco is known for keeping the rhythm so you don’t feel rushed through the good parts.
Cala Mariolu: Your 1-Hour Beach Reset

Your first stop is Cala Mariolu, with a full 1 hour at the beach. You disembark and re-board at the dock.
Why this stop works: it’s the launchpad of your day. By the time you land here, you’ve already started early, so you’re more likely to enjoy the beach without fighting for space. You’ll have enough time to settle in, take a proper dip, and get oriented before the itinerary starts stacking up.
The boat-and-beach flow is also clear here. You’re not trying to guess timing or coordinate with other groups. It’s a straightforward landing at a dock, then back on board.
Cala dei Gabbiani: A Sand-Boarding Stop When Spots Allow

Stop two is Cala dei Gabbiani, and it comes with an important condition: it’s subject to availability. When it’s on the itinerary, you’ll disembark and board directly on the sand, and you’ll get 1 hour.
The sand-boarding detail is more than a technical note. It usually means less friction getting in and out, so you spend more of your hour actually using your time rather than waiting around to transfer.
Because availability depends on daily municipal assignments, this is one of the stops you shouldn’t set your day clock by. If it’s included, great. If not, the operator will still keep the structure of beach time in place while working within what the municipality allows.
Other boat tours in Sardinia
Inside Grotta del Fico: 50 Minutes, 20°C Cave Time, and Sea Siphons

This is the headline portion. Grotta del Fico comes next for a 50-minute guided tour inside the cave.
A few things you should know before you go in:
- The inside temperature is about 20°C, so it can feel noticeably cooler than the sun outside.
- You’ll see rock formations, plus underground rivers and sea siphons.
- You can take pictures and videos inside.
What makes this special is the combination of included entry and guided interpretation. Many coastal trips stop at dramatic views, but this one gives you something different: a below-sea-level world. The guided component also helps you connect the formations to how the cave functions, not just what it looks like.
If you’re the type who likes photos, plan to use your time early. Once you’re inside, you’ll follow the guide’s pacing, and the cave is structured so everyone moves together. Wearing comfortable clothes helps because you’ll be in cave space long enough that you’ll want to feel good, not just look good.
Cala Biriala: When You Get It, You’ll Appreciate the Beach Time

Next is Cala Biriala, again subject to availability, with a 1-hour beach stop. When it’s included, you disembark and board directly on the sand.
This stop is often where the day starts to feel like vacation, not logistics. A key advantage is the pacing the guide aims for. One of the best pieces of advice I can offer is to lean into the early timing of the whole trip, because it can translate into quieter beach time when you arrive first.
Even if your specific stop sequence shifts due to visitor-flow rules, the operator’s goal is still the same: protect beach time and avoid making you feel like you’re sprinting from one point to another.
Piscine di Venere and Cala Goloritze: Quick Anchor Swims With Big Visual Payoff

After the beach stops, the itinerary switches gears to two shorter swim moments at anchor.
Piscine di Venere (20 minutes, free)
You stop for a swim at anchor for 20 minutes. The color of the sea bottom is described as stunning, and that matches what this stop is known for: short time, but enough to enjoy the water and look down into the shallows.
Cala Goloritze (20 minutes, free)
You also get 20 minutes to swim at anchor in front of Cala Goloritzè. There’s an important access note: there is no access for boats there, so it’s reachable only by feet. Practically, what that means for you is that your time is about swimming and taking in the view from the sea, not about walking around the famous cove itself.
These anchor swims make the day feel varied. You’re not stuck only on docks. You’re also not stuck only in a cave. You get sea time in two different flavors: one more about colors at shallow depths, the other more about the view and the setting.
Cala Sisine: Final Beach Stop Before the Return
The last beach stop is Cala Sisine, also subject to availability, with 1 hour at the beach.
Like Cala dei Gabbiani and Cala Biriala, this is one of the stops that may be included or adjusted based on daily municipal spot assignments. But if you do get it, it gives you a strong closing stretch to the day.
Because it’s the final beach stop, it’s a good time to be intentional:
- Give yourself enough minutes to actually enjoy the sand and water, not just a quick dip.
- If you’re planning photos, this is often where you’ll want to capture the late-day light vibe, depending on the sun and weather that day.
What You Get for $111.47: Value Breakdown That Makes Sense
At $111.47 per person, this tour is priced like an all-in coast experience, not like a bare-bones boat rental. The value comes from the way the inclusions line up with what can be hard to piece together on your own.
Here’s the value logic:
- Grotta del Fico entrance tickets are included. That’s a major selling point because you’re specifically getting cave admission as part of the trip.
- Municipal beach access fee is included: €3 per person.
- You get admission tickets for included beach stops listed on the itinerary.
- You also get small conveniences: a sun umbrella and fridge bag, if you request them in advance.
- Food and drinks are not included, so plan on bringing your own strategy (or buying on land), but the boat-and-admissions portion is clearly covered.
When you compare this kind of coast day, the cave access and municipal fees are usually where trips start costing real money in extra tickets. Here, those costs are already wrapped into the price. For many people, that alone makes it feel fair.
Tips for Enjoying the Day Without Feeling Rushed
This is an 8-hour boat day, and the stops stack up. The trick is to treat each stop as its own mini-mission.
- Use the first hour well at Cala Mariolu. By then, you’ll know where you want to place yourself for easy swimming and quick photos.
- Bring a light layer for Grotta del Fico. The cave is around 20°C, which can feel cool.
- Plan your swim time at Piscine di Venere and Cala Goloritze. Each is short at 20 minutes, so don’t spend the whole slot faffing.
- Stay flexible about beach stops besides Cala Mariolu. Under the August 2025 visitor-flow ordinance, other beaches can change based on daily assignments.
If the guide suggests a pace, follow it. Guides like Francesco are praised for how they manage timing so you get both views and actual time on the beach.
Who This Boat Trip Suits Best
This trip is a great fit if you want:
- a guided cave experience with included tickets,
- multiple beach stops with real time at each one,
- short anchor swims rather than long, exhausting transfers.
It’s especially worth it for couples and small groups who like a structured day. With a max group size of 12, it also suits people who don’t want a huge crowd vibe.
If you’re the kind of traveler who needs every stop to be guaranteed, keep one thing in mind: only Cala Mariolu is guaranteed under the current rules. Everything else can shift.
Should You Book This Boat Trip?
Yes, I’d book it if Grotta del Fico is high on your list and you want the cave organized as part of a coast day. The included tickets are the standout value, and the overall pacing is built for views plus beach time, not just check-the-box stops.
I’d also book it if you’re okay with mild itinerary changes in August 2025, as long as you’re excited for the idea of reaching at least one guaranteed beach and adding a few additional sand-and-swim moments when permitted.
If you tell me your travel month and what matters most (caves, beach time, or swimming), I can help you judge whether this schedule style fits your pace.
