The stretch of north-western coast in Sardegna between Alghero and Bosa calls for careful planning to balance sightseeing hours, drives, and cliffside parking. Choosing your stops wisely prevents rushing and leaves plenty of time for the scenic coastal road and the steps leading down to the sea.
In terms of timing, shoulder seasons such as May, early June, September, and early October are ideal. The weather is warm, the sea is perfect for swimming, and the towns are free from peak-summer crowds. To travel between stops, a hire car is practically essential.
A practical two-day itinerary
Day 1 — The Alghero coast and Capo Caccia
Morning
Start the day in Porto Conte at Spiaggia delle Bombarde, a cove of pale sand and crystal-clear water. Arrive early to beat the crowds and secure a good spot. By mid-morning, head towards Capo Caccia to explore Grotta di Nettuno ed Escala del Cabirol, a karst marine cave reached either by boat or by tackling the 654 steps carved into the cliff. Keep in mind that booking a time slot online is always mandatory if you plan to walk down.
Afternoon
Heading back towards town, spend an hour at the Museo del Corallo, housed in an Art Nouveau villa that traces the heritage of harvesting and working red coral, long the civic symbol. A short stroll away in the historic centre of Alghero stands the Cattedrale di Santa Maria Immacolata, a Catalan-Gothic cathedral: a visit takes around 30 minutes and lets you climb the bell tower for sweeping views across the old town.
Evening
Sunset is the best time for a stroll along the Bastioni e Centro Storico di Alghero. Walking along the ramparts (Bastioni Marco Polo and Magellano) takes between one and two hours. For dinner in the historic centre, Trattoria Caragol is an authentic spot loved by locals, renowned for its agliata algherese and maccarones de busa with clams. For fresh daily catch paired with homemade pasta, Trattoria da Mirko is another excellent choice.
Day 2 — The coastal drive and the Temo river
Morning
In the morning, head south along the Strada Panoramica Alghero-Bosa (SP 105 / SP 49), hugging the western coastline. This 45 km stretch of road winds above pink trachyte cliffs and takes just over an hour at an easy pace. Once in Bosa, make your first stop on Colle di Serravalle at Castello Malaspina (Castello di Serravalle), a 12th-century medieval stronghold that still houses its frescoed palatine chapel.
Afternoon
Walk down from the castle through Borgo Sa Costa, Bosa's historic centre. This maze of cobbled lanes is lined with brightly painted houses clinging to the hillside. Spend the rest of the afternoon unwinding on Spiaggia di Bosa Marina, a wide, sheltered sandy beach watched over by the 16th-century Aragonese Torre dell'Isola Rossa. If staying overnight here, the nearby Hotel Baja Romantica is just steps from the marina.
Evening
As dusk falls, head back towards the centre of Bosa to photograph Ponte Vecchio e Lungofiume Temo. Built from red trachyte, the bridge spans the island's only navigable river and offers a great vantage point in the evening light. For dinner, options include Locanda di Corte in the historic centre for Planargia specialities, Trattoria Sa Nassa facing the bridge for land and sea dishes, or Ristorante Pizzeria Sa Pischedda by Ponte Vecchio, a historic venue serving sea urchin pasta and wood-fired pizzas.
