Five days is enough time to get a real feel for Northwest Sardinia without rushing from place to place. This itinerary is built around Alghero and the Northwest as a single, comfortable base, with day trips that fan out to the coast, the countryside and one of the island’s most memorable natural landmarks. It’s designed to connect naturally with everything else we’ve covered in this region, without repeating it.
Below you’ll find the full day-by-day plan, honest notes on driving times and reservations, and an alternative pace for travelers who prefer to slow down and split their stay.

Why Base Yourself in Alghero
Alghero sits close to almost everything in this itinerary. The historic center is walkable, several beaches are a short drive away, while Capo Caccia typically takes around 35–45 minutes to reach, depending on traffic and your starting point, and Bosa is reachable in a morning. Basing here means you unpack once and spend your time seeing Sardinia rather than moving between hotels. It also puts you within easy reach of Alghero’s own historic center and Bastioni, which are worth returning to more than once, especially in the evening when the ramparts are at their best.
Do You Need a Car?
A rental car is strongly preferable. Alghero’s old town itself is entirely walkable, and some beaches near the city are reachable by local bus in high season, but Capo Caccia, Neptune’s Grotto and Bosa all require a car to do comfortably. It’s possible to cover this itinerary using a combination of buses, boat excursions and organized day tours instead, but that route requires more advance planning, ties you to fixed departure times, and gives you far less flexibility to change plans around weather, especially for the cave visit, which depends on sea conditions. A rental car gives you the freedom to adjust course if the day doesn’t go as expected.
The Itinerary at a Glance
- Day 1: Arrival and Alghero’s historic center and Bastioni
- Day 2: Beach day near Alghero
- Day 3: Neptune’s Grotto and Capo Caccia
- Day 4: Bosa day trip via the scenic coastal road
- Day 5: Flexible day — choose your pace
Day 1: Arrival and Alghero’s Historic Center
Use your first day to settle in and get oriented rather than packing in a full agenda, especially if you’ve just landed. Alghero’s old town rewards slow wandering more than a checklist: its Catalan-influenced streets, the sea walls, and the golden light along the Bastioni at sunset are best experienced without a schedule. We’ve covered the neighborhood in detail in our Alghero destination guide, including how the different quarters of the historic center connect and where the ramparts offer the best evening views. A relaxed dinner near the old port is a good way to close out the day and get your bearings for the rest of the trip.

Day 2: Beach Day Near Alghero
Dedicate a full day to the coastline. The beaches around Alghero vary quite a bit in character, from wide sandy stretches to smaller coves, and which one suits you best depends on whether you’re after calm water, space to spread out, or a livelier atmosphere. Rather than repeat those details here, our guide to the best beaches near Alghero breaks down the options so you can pick based on your own priorities. In peak summer, arriving earlier in the day makes a real difference, both for parking and for finding a comfortable spot before the midday crowds settle in.
Day 3: Neptune’s Grotto and Capo Caccia
This is the day built around Northwest Sardinia’s best-known natural landmark. Capo Caccia’s cliffs and the cave system at Neptune’s Grotto are genuinely dramatic, but the visit is worth planning around rather than assuming it will simply happen. Access depends heavily on the weather and sea conditions. Rough seas can suspend boat service, while unfavorable conditions can also close the cave to land visitors. The stairs should not be treated as a guaranteed backup. It’s worth building in some flexibility on this day rather than scheduling something tight immediately afterward. Our full Neptune’s Grotto and Capo Caccia guide goes into the access options, the stairway versus boat trade-offs, and the mandatory land-reservation process and current access procedures, so we won’t repeat that here. Allow at least half a day, or longer if you want to explore more of Capo Caccia and Porto Conte.

Day 4: Bosa Day Trip via the Scenic Coastal Road
The drive from Alghero to Bosa along the coastal road is one of the most memorable in the region, and it’s a big part of the day, not just a way to get somewhere. The road hugs the cliffs with almost no development along the way, which makes for slow, winding driving rather than a quick hop between towns. Realistically, budget more time for the drive than the distance on a map would suggest, and be cautious about tackling it after dark or in poor visibility. In peak summer, this road can also see meaningful traffic, particularly around midday, so an earlier start tends to make for a more relaxed drive in both directions. Once in Bosa, the pace shifts entirely, from colorful riverside houses to the hilltop castle. We cover the full route, stops along the way and what to do once you arrive in our Bosa day-trip guide.

Day 5: Flexible Day — Choose Your Pace
By day five, most travelers fall into one of two camps: those who want one more substantial outing, and those who’d rather slow down before departure. Both are reasonable choices, so this day is left open rather than fixed.
- For archaeology: Nuraghe Palmavera and the Anghelu Ruju necropolis are both close to Alghero and offer a look at Sardinia’s prehistoric past without a long drive.
- For nature: Porto Conte Regional Natural Park offers a slower, greener side of the region, with coastal trails and open landscape rather than structured sightseeing.
- For a slower finish: a return to whichever Alghero-area beach you liked best on Day 2, followed by a final evening on the Bastioni, closes the trip on familiar, unhurried ground.
Alternative: The Split-Stay Version for Slower Travelers
If you’d rather not treat Bosa as a single long day trip, consider splitting your stay: three nights in Alghero covering Days 1 through 3 as above, then relocating to Bosa for the final two nights instead of driving back and forth. This removes the return leg of the coastal drive from your schedule entirely, lets you experience Bosa in the early morning and evening once the day-trip crowds have thinned, and generally suits travelers who prefer fewer transitions and more downtime over covering more ground. The trade-off is one additional check-in and check-out, and slightly less proximity to Alghero’s own beaches and historic center on your last days.
Practical Notes: Traffic, Reservations and Timing
A few honest planning notes worth keeping in mind as you build out the specifics:
- Summer traffic: July and August bring noticeably heavier traffic on the roads to Capo Caccia and along the Bosa coastal road, particularly midmorning through early afternoon. Earlier starts consistently make for a smoother day.
- Weather-dependent access: Neptune’s Grotto’s boat access can be suspended in rough seas, and the cliffside stairway isn’t guaranteed to be open either. Treat this day as flexible rather than fixed, and have a backup plan in mind.
- Reservations: Land access to Neptune’s Grotto requires a mandatory reserved time slot. Boat transportation is arranged separately and may also require advance planning, especially in summer. Other popular sites can require advance booking during peak season too, so it’s worth checking current requirements shortly before your trip rather than assuming availability on arrival.
- Parking: Alghero’s historic center has limited parking directly inside the walls, so many visitors park just outside and walk in.
Bringing It All Together
Used together, these five days give you a genuine sense of Northwest Sardinia: a walkable historic town, its beaches, one of the island’s standout natural sights, and a beautifully situated neighboring town, all without feeling rushed.
