Lazzaretto Beach is excellent for swimming with calm, clear turquoise waters protected by its cove formation. The rocky seabed and transparent water make it ideal for snorkeling, with opportunities to observe Mediterranean marine life including fish and sea plants. Water depth increases gradually in most areas, suitable for various swimming abilities. The series of small coves means you can find sheltered spots even on windier days. No lifeguards are present, but the generally calm conditions make it a popular family swimming destination.

Visit Lazzaretto Beach from May through September for the best weather and warm water temperatures. July and August are peak season with the warmest water but also the most visitors, so arrive early for parking and space. June and September offer pleasant swimming conditions with fewer crowds, ideal for snorkeling when water clarity is excellent. The beach is accessible year-round, and even off-season visits can be enjoyable for walks and scenery, though swimming is only comfortable in warmer months.

Lazzaretto Beach stands out for its series of small, intimate coves carved into rocky coastline, each offering slightly different character and shelter. The name derives from a historic lazaretto (quarantine station) that once stood nearby. The beach combines sandy patches with rocky areas and exceptionally clear turquoise water that appears almost tropical in sunlight. Its proximity to Alghero yet quieter atmosphere compared to more central beaches appeals to visitors seeking natural beauty without traveling far. The snorkeling conditions are particularly notable for the area.
