Monterosso is the largest of the five villages and is divided into two distinct parts: the old town and the new town. The old town, with its narrow streets and historic buildings, is characterized by its medieval architecture and charming atmosphere. The new town, on the other hand, has a more modern feel with hotels, restaurants, and shops lining the waterfront. Monterosso is known for its beautiful sandy beach, making it a popular destination for sunbathing and swimming.
