1. Lu Bagnu Beach: Family-Friendly Golden Sands

Golden sand warms your toes as the gentle Mediterranean laps at your feet in this picturesque town in Sardinia on the northern Sardinia coast. I watched local families set up picnic blankets early, before the Blue Flag beach fills with midday laughter and visitors weighing things to see in nearby Sassari and how to get to Castelsardo for a day by the sea. Lu Bagnu Beach is a wide sandy bay stretching about 1 km, ideal for swimming in clear, shallow waters beneath the silhouette of the Castello dei Doria — perfect from June through September.

The Lay of the Land & Local Advice:
Walk past the bustling Piazza del Novecentenario, then down to the promenade lined with seafront pizzerias and gelaterias. The beach’s eastern end has a wheelchair ramp, while the western entrance leads to a quieter stretch near the historic fishing jetty. Locals swear by the tiny kiosk tucked behind the rocks for fresh pane carasau and icy lemonade. Arrive before 10 AM in July or August for a prime spot; parking is easiest at the large lot above the beach, just off Strada Provinciale 90.

  • Pro: Shallow, calm waters and lots of facilities — great for families and anyone wanting hassle-free beach time.
  • Con: Gets crowded in peak summer — arrive early or visit in shoulder season for more space.

Best For: Families, swimmers, and anyone who wants easy access to amenities.
Skip If: You’re seeking wild, untouched nature — head to Baia Ostina or Cala La Vignaccia instead.

2. Baia Ostina Beach: Wild Beauty in a Rocky Cove

The rhythmic crunch of pebbles underfoot mixes with the distant cries of gulls as you descend to this hidden bay outside Castelsardo, a stretch known for beautiful beaches along northern Sardinia. I scrambled over smooth boulders to find a private perch where the water’s clarity stunned me, thinking about nearby beaches toward Santa Teresa and the easy routes from Olbia for day-trippers. Baia Ostina Beach is a small pebble cove framed by dramatic cliffs — the sea here is deep and perfect for a refreshing plunge, best enjoyed from late May to early October, and you won’t need to carry a basket of gear thanks to the short walk and simple access.

On-the-ground Feel & Insider Tips:
Park at the small lot off Strada Statale 134, then follow the rocky path down to the water — sturdy shoes are a must, and plan accommodation logistics before sunset if you’re staying beyond town. There are no sunbeds or bars, so pack a picnic and plenty of water, then visit the small church of Santa Maria delle Grazie in the evening back in Castelsardo. The viewpoint above the bay (ask locals for il belvedere) is a sunset favorite, with panoramic vistas over the Gulf of Asinara and clear sightlines to nearby beaches.

  • Pro: Unspoiled, peaceful, and photogenic — a true escape from the crowds.
  • Con: No facilities and tricky access — not ideal for small children or anyone with mobility challenges.

Best For: Adventurous spirits, photographers, and anyone craving solitude.

3. Marina di Castelsardo Beach: Old Town Charm by the Sea

The scent of salt and frying calamari drifts from the seafront trattorias as you step onto this small beach overlooking the sea beneath the castle walls shaped by the Doria family. I loved sitting on the low wall here at dusk, watching fishing boats bob in the golden light as the maestro di Castelsardo’s legacy echoes through the old lanes carved from roccia. Marina di Castelsardo Beach is a 50-meter stretch of brown, coarse sand right at the foot of the old town, with clear, calm water — ideal for a quick dip from May to September and a scenic pause before exploring Gallura.

Navigating the Neighbourhood & Insider Knowledge:
Emerge from Via Roma into Piazza Cristoforo Colombo, where the beach unfolds just beyond the small harbor. There’s a shower and a couple of shaded spots, but no real infrastructure — you’re here for the atmosphere, not the amenities. The historic center’s alleys, dotted with artisan boutiques and the Museo dell’Intreccio Mediterraneo, are just steps away. Locals love their evening passeggiata along the Lungomare Anglona, the scenic promenade linking the beach to the old town.

  • Pro: Central, atmospheric, and perfect for combining beach time with sightseeing.
  • Con: Small and can feel crowded — better for a brief swim than a full-day outing.

Best For: Couples, culture buffs, and anyone staying in the historic center.
Skip If: You want a classic day-at-the-beach vibe — drive to Lu Bagnu or Pedraladda instead.

4. Pedraladda Beach: Windsurfing and Wide Open Spaces

A steady breeze tugs at your hair as you walk the length of this exposed crescent of sand, a reminder that Castelsardo is a picturesque coastal hub shaped by winds and tradition. I borrowed a paddleboard from a local instructor and skimmed over turquoise rollers, watching serious windsurfers carve the horizon as the maestro di Castelsardo once inspired artisans beneath the bell tower. Pedraladda Beach is a sandy stretch about 500 meters long, favored for wind sports from April to October, when the maestrale wind picks up and arrivals from Alghero-Fertilia or ferries toward Palau find a central location on the north coast.

Atmosphere & A Pro Tip:
Turn off the SS134 onto Via dei Cantoni and park at the edge of the dunes, a straightforward route whether you fly into Alghero-Fertilia or plan coastal drives toward Palau. There are no fixed sunbeds, but a seasonal snack bar pops up in summer, and locals nod to the legacy of Abate as they unroll mats for sunrise yoga on the eastern end. The beach is flanked by wild juniper and myrtle scrub, and locals come here for sunrise yoga sessions on the eastern end where the bell tower silhouette anchors the skyline. It’s a short drive to Sedini, where the Domus de Janas rock tombs make a fascinating side trip, showing why Castelsardo is a central base for day trips.

  • Pro: Reliable winds and space to spread out — a hit with active visitors.
  • Con: Exposed and sometimes windy — not the best for calm swimming or sunbathing purists.

Best For: Windsurfers, kiteboarders, and anyone seeking an energetic beach day.
Skip If: You’re after calm, sheltered waters — opt for Lu Bagnu or Marina di Castelsardo instead.

5. Cala La Vignaccia Beach: Secluded Sunbathing in a Hidden Cove

Pine-scented shade and the soft crunch of golden sand underfoot welcome you to this quiet corner on the northern coast of Sardinia, a serene pause on any visit Castelsardo itinerary. I found a pocket of stillness here one August morning, sharing the cove with just a handful of locals while considering the best things to see in the town of Castelsardo beyond the shoreline. Cala La Vignaccia Beach is a 100-meter sandy cove between rocky outcrops — best from June to September for swimming and snorkeling in clear, protected waters.

The Lay of the Land & Local Advice:
Access is via a short path from the parking area off Strada Provinciale 90, near the turn for Lu Bagnu, making it an easy thing to do in Castelsardo between swims and scenic stops. Bring everything you need, as there are no facilities; the reward is privacy and unspoiled nature that fits the spirit of the best things to see on this coast. The nearby Torre di Punta La Capra, a 16th-century watchtower, offers sweeping views up the coast that frame the wider northern coast of Sardinia.

  • Pro: Peaceful, natural, and rarely crowded — a true hideaway.
  • Con: No services and a bit of a walk — pack light and wear sturdy shoes.

Your footsteps echo as you pick your way over sun-warmed boulders to this secret spot on the northern coast of Sardinia, a quiet highlight to include among the things to see in Castelsardo during any trip to Sardinia. I slipped into the cool water here and spent an hour exploring the rocky seabed with my snorkel, then looked back toward the historic center of Castelsardo rising above the marina. Cala Sant’Antonio Beach is a rocky cove near the marina, with clear, deep water and excellent visibility — prime for snorkeling from late May to early October and an easy short drive from Castelsardo to other coves.

On-the-ground Feel & Insider Tips:
Park near the small harbor and follow the coastal path westward for about 15 minutes; the cove is just past the last houses and a calm detour before you continue to Roccia dell’Elefante. There’s no sand, just smooth rocks and a few natural platforms for sunbathing, so plan your timing mid-morning if you’re combining multiple things to see in Castelsardo. The best time to visit is mid-morning, before the sun gets too intense, and the return walk brings you toward the historic center of Castelsardo for a late lunch.

  • Pro: Crystal-clear water, great for snorkeling and escaping the crowds.
  • Con: Rocky and difficult for small children or anyone needing easy entry.

Best For: Snorkelers, adventurous couples, and fans of wild swimming.

7. Ampurias Beach: Beach Bar Buzz and Lazy Afternoons

The hum of conversation and clinking glasses drifts from the beach bar as you settle into your rented sunbed on the island of Sardinia, a mellow pause in a day exploring sardinia and the islands. I spent a lazy afternoon here, alternating dips in the sea with plates of friselle and cold Vermentino while mapping the best places to wander west of Castelsardo along this easygoing shoreline. Ampurias Beach is a 200-meter stretch of golden sand, with calm, shallow water and a laid-back, social vibe — ideal from late June to early September and a friendly first stop after any airport to Castelsardo transfer.

Navigating the Neighbourhood & Insider Knowledge:
Turn off Strada Provinciale 90 at the sign for Ampurias and park in the small lot; follow the steps down to the beach for one of the best places to enjoy sunset on the northern coast near Lu Bagnu. Sunbeds and umbrellas are available for rent, and the bar serves light snacks and drinks all day, which makes it an easy choice if you arrive directly from an airport to Castelsardo connection.

8. Vela Blu Beach: Natural Oasis with Shallow Waters

The scent of sun-cream and salt mixes with the rustle of seagrass as you wade into ankle-deep turquoise next to the sea, a gentle corner with views of the sea that families love. I watched local kids hunt for crabs in the tidal pools while their parents dozed under rented umbrellas, a simple pleasure that echoes the craft traditions showcased at the museum of mediterranean weaving in the historic center. Vela Blu Beach is a 150-meter stretch of fine sand with exceptionally shallow, calm water — great for families with small children from June to September and a relaxed alternative to busier routes toward Santa Teresa di Gallura.

Atmosphere & A Pro Tip:
Enter from the end of Via Venezia, where a small parking area serves the beach with quick access right next to the sea and wide views of the sea. There are no bars or vendors, so bring snacks and water, then plan a short detour to the museum of mediterranean weaving to connect beach time with local heritage founded by the Genoese Doria influence.

9. Poltu di la Rena Beach: Sandy Solitude with a View

Waves whisper against the shore as you spread your towel on this quiet stretch of golden sand. I had the eastern end to myself one September afternoon, watching fishing boats trawl the horizon. Poltu di la Rena Beach is a 300-meter sandy bay with gentle waves and a view toward the Asinara island — best for swimming and sunbathing from June to September.

10. Punta li Paddimi Beach: Adventurer’s Cove Off the Beaten Track

A narrow goat path winds down to this hidden slice of coast, where waves crash against black volcanic rocks. I scrambled over boulders to find a perfect perch for my book, with only the sound of the sea for company. Punta li Paddimi Beach is a rocky cove with deep, clear water and strong currents — best left to confident swimmers and snorkelers from July to September.

On-the-ground Feel & Insider Tips:
Access is from a discreet parking spot off the road to Tergu, then a 10-minute walk along a rough path — sturdy shoes are essential and the wild feel is worth a visit.

A breeze cools your face as you perch on a rocky ledge, watching sailboats skim the horizon. I loved the sense of height and space here, far from the busier beaches below. Punta la Capra Beach is a series of rocky platforms and tiny coves, with deep, clear water and a sense of adventure — ideal for confident swimmers and sunbathers seeking a view from June to September.

Navigating the Neighbourhood & Insider Knowledge:
