Practical Information

Location

Bosa and Alghero are two stunning coastal towns located in Northern Sardinia, Italy’s second-largest island, nestled in the heart of the Mediterranean Sea—just south of Corsica and west of mainland Italy.

Transportation & Exploration

✈️ By Plane: You can easily reach Northern Sardinia via Alghero🔗 or Olbia🔗 airports.

👉 Alghero is especially convenient if you're heading to the northwest coast

🚐 By Car: The best way to explore the region—including scenic routes like the coastal road between Alghero and Bosa—is by renting a car. This gives you the freedom to visit remote beaches, colorful villages, and panoramic viewpoints at your own pace.

👉 I book my rentals on Booking🔗, where I’ve been finding the best deals lately

 🚆Public transportation: While buses do connect the main towns, public transport is relatively limited and not the best option if you want the freedom to make spontaneous stops or explore more off-the-beaten-path spots. 

👉 Ferries are also widely available and offer an easy way to reach nearby islands, including the stunning La Maddalena archipelago, making island-hopping a convenient addition to your itinerary.

Alghero

Alghero, known as “Barceloneta” for its Catalan influence, is one of Sardinia’s most charming coastal towns, blending history, culture, and natural beauty.

What you can't miss in Alghero:

• Historic center: where cobblestone streets lead to medieval walls, colorful piazzas, and landmarks like the Cathedral of Santa Maria and Torre di Sulis. Stroll along the Bastioni Marco Polo, a picturesque promenade offering stunning views of the sea, especially at sunset.
• Neptune’s Grotto🔗: a spectacular sea cave located at the base of Capo Caccia cliffs. Accessible by boat or the thrilling Escala del Cabirol staircase, this adventure rewards you with views of stalactites, stalagmites, and underground lakes. I opted for the stairs but consider that they are quite long.

As the sun begins to dip, the sky transforms into a canvas of vibrant hues—gold, orange, and pink—casting a warm glow over the cliffs and the endless expanse of water. The atmosphere is serene, with the sound of waves crashing below and the occasional call of seabirds echoing in the distance.
