Key takeaways
- The catamaran visits coves and sea caves along the Gulf of Orosei, with the exact lineup determined by wind, weather, and access permits issued daily.
- Plan for roughly 30-45 minutes at each anchorage, depending on conditions and how many coves the captain includes on the day's route.
- Some beaches near Arbatax allow you to step ashore; others are anchor-only due to environmental protection limits and visitor quotas enforced by permit.
- Several stops feature sea caves you can swim into and explore, though entry depends on sea state and whether that day's permit allows the stop.
- The Baunei coast sits roughly 20-30 kilometres south by sea, reachable comfortably within the 8-hour sailing window from Arbatax.
The Sailing Route from Arbatax North
Your catamaran departs Arbatax and heads north along the Baunei coastline, one of Sardinia's most dramatic stretches of Mediterranean water. The journey covers approximately 20 nautical miles of open sea, with the red granite cliffs rising vertically from the water. The route takes you past the Gulf of Orosei, where the terrain shifts from sandy beaches near Arbatax to increasingly rugged limestone formations as you venture deeper into protected waters. Depending on sea conditions and wind direction, the captain plots a course that typically takes between 1.5 and 2 hours to reach the first major stop. Along the way, you'll pass smaller coves and rocky outcrops that serve as waypoints for the day's navigation.
The coastline itself tells a geological story. Near Arbatax, the beaches transition from sand to pebble, then to smooth rock platforms as you move north. Many of these formations sit at the base of caves near Arbatax, where millennia of wave action have carved openings directly into the cliff face. The captain maintains radio contact with other vessels and shore stations to monitor changing conditions, as this northern approach can become choppy when northwesterly winds pick up in the afternoon.
Candidate Coves and What You'll Find There
The catamaran typically considers four or five major stops, each with distinct characteristics. Cala Luna features a sandy crescent beach backed by a freshwater spring, where you can swim and rest on soft ground. Cala Sisine offers a pebbled shore and sits at the mouth of a river canyon, creating a freshwater pool near the water's edge where visitors often rinse salt from their skin. Cala Biriola presents a more intimate rocky cove surrounded by high walls, with a small sandy patch perfect for brief swimming stops. Cala Goloritzè is perhaps the most famous, though access here follows a strict environmental permit system rather than unlimited landings.
Each cove presents different swimming and beach conditions. Some offer shallow water close to shore, ideal for entering gradually, while others drop off quickly. Rocky coves demand careful entry and water shoes are worth considering, though they're not provided as part of the tour. The sand at Cala Luna is notably finer than at other stops, making it popular when sea conditions permit a longer stay there.

Sea Caves You Can Swim Into
Several stops feature sea caves accessible directly from the water. At Cala Goloritzè, a large grotto sits at water level, and swimmers often paddle into the cave entrance to experience the interplay of light on water and stone. The cave mouth is wide enough for several swimmers to enter simultaneously, though the captain assesses conditions before allowing water entry. At Cala Sisine, smaller cave openings punctuate the cliff face, and depending on water level and wave action, you may swim near these formations. The caves near Arbatax further south are less frequently visited by this tour but represent the geological origins of the entire region.
Cave exploration depends entirely on sea state. Calm, glassy conditions allow swimmers to venture into cave mouths and observe the cathedral-like interiors lit by daylight filtering through the entrance. When swells build, even experienced swimmers stay clear of cave entries due to the compression and release of waves within confined spaces. The captain makes these decisions in real time based on atmospheric pressure, wind direction, and sea state observations.
Why the Itinerary Changes Day to Day
No two days on this catamaran tour follow identical routes. Wind direction is the primary driver of these changes. When northwesterly winds blow, the captain may skip exposed northern coves and instead favor the more sheltered bays closer to Arbatax. Southeasterly winds open up different possibilities, allowing access to coves on the gulf's western flank. Wave height, swell period, and underwater currents all factor into the captain's decision-making. A forecast that calls for afternoon wind strengthening might push the departure earlier and compress the number of stops.
Seasonal variations also reshape the itinerary. Summer sees more stable weather patterns and longer stretches at each cove, while spring and autumn bring more variable conditions that may shorten stops or eliminate certain locations entirely. The captain communicates the day's plan to passengers during the morning departure briefing, explaining which coves are feasible and why others have been ruled out. This flexibility is not a flaw but a safety feature that prioritizes passenger wellbeing over rigid scheduling.
Environmental Limits and the Access Permit System
Cala Goloritzè and several other prime locations operate under an environmental protection regime that limits daily visitors. Permits are allocated to boats based on capacity and time of year, with the catamaran receiving a fixed allocation for each sailing date. When permits are exhausted, no additional visitors can land at that cove, even if weather permits. This system emerged from decades of erosion and vegetation damage caused by overcrowding. The captain understands these constraints and plans accordingly, sometimes arriving at a cove early to secure a time slot or pivoting to alternative stops if permits have been issued to other operators.
This environmental contribution system means that not every passenger on every tour reaches the most famous coves. If you've booked expecting a specific beach visit, the captain will explain the permit situation and offer alternative experiences of comparable quality. The permit system represents a broader commitment to preserving these ecosystems for future visitors, and the limitation actually enhances the experience by preventing the overcrowding and degradation seen at some Mediterranean destinations.
Time at Each Stop and Swimming Duration
Swimming time varies between 30 and 90 minutes depending on the cove, sea conditions, and permit availability. Larger, more popular beaches like Cala Luna typically receive longer allocations, while smaller coves or those with environmental restrictions may see shorter stops. The captain anchors in water deep enough to allow safe exit via the catamaran's swim platform or tender access. Before dropping anchor, crew members brief all passengers on water safety, sea conditions, and the expected duration of the stop.
Most swimmers enter and exit within the first 20 minutes, leaving 10 to 60 minutes for actual water time depending on the stop. Sunbathing on small beaches or relaxing in the water accounts for the bulk of time at each location. The captain signals when the stop is ending, and passengers should return to the boat promptly to avoid delaying the day's subsequent activities and to respect the permit windows at protected coves.
Sandy, Pebbly and Rocky Shores Explained
The geology of the Baunei coastline creates diverse beach types within a short distance. Cala Luna's sand is the product of river erosion and coastal drift, creating a soft, comfortable beach suitable for families and anyone sensitive to rocky terrain. Cala Sisine's pebbles range from marble-sized to egg-sized stones, rolled smooth by decades of wave action but still uncomfortable for bare feet over extended periods. Cala Biriola transitions between rock platforms and small sandy pockets, requiring careful navigation but rewarding explorers with dramatic formations. Rocky coves like those near the cave formations offer no sandy beach at all, instead providing smooth or rough stone platforms where swimmers enter and exit the water.
The type of shore at each stop matters for comfort and safety. Sandy beaches allow extended lounging and suit those who dislike sharp stones. Rocky coves suit photographers and adventurous swimmers but demand water shoes or caution. Most swimmers bring flip-flops and rinse their feet during stops with freshwater access, such as Cala Sisine. The catamaran carries fresh water on board for rinsing salt after swimming, and crew members point out the best entry and exit points at each cove based on that day's water conditions.
