How Albania’s Blue Eye was formed – and how to visit responsibly

Widely regarded as one of the Balkans' most striking natural landmarks, the Blue Eye is a natural spring in southern Albania, located between the cities of Saranda and Gjirokaster. Named after the surreal colour and exceptional clarity of water, the constant flow of crystal-clear water creates a mesmerising visual effect, giving the impression of a giant eye looking up from beneath the surface.

Underground water systems and limestone geology

The Blue Eye was formed within a karst landscape, where water gradually dissolves limestone, creating underground caves and fissures. Water flows through these underground channels, resulting in pressure forcing water upward. This process, known as a karst resurgence, produces the Blue Eye's continuous flow of impressively clear water.

Why the water looks so intensely blue

Its remarkable colour is a result of light refraction, mineral composition, and water clarity and depth. As sunlight hits the crystal-clear water, it's scattered in a way that enhances blue wavelengths, creating beautifully vibrant shades of turquoise and deep sapphire. The spring's great depth intensifies this effect, while the low levels of sediment and impurities allow light to travel through easily, contributing to its transparency.

How deep is the Blue Eye?

Divers have descended beyond 50 metres without reaching the bottom of the spring, suggesting it's deeper than what's visible from the surface. Due to strong underwater currents and limited access to deeper sections, the exact depth of the Blue Eye remains unknown. This uncertainty has added to the attraction's sense of mystery and intrigue, with speculation surrounding what lies beneath the blue waters.

The Blue Eye is much more than just a tourist attraction in southern Albania; it's a delicate freshwater ecosystem sustained by a karst spring system. It supports limited aquatic life, mainly small invertebrates and microorganisms adapted to cold, oxygen-rich karst spring conditions. Surrounding woodland and riparian habitats support local biodiversity, providing shelter for birds, insects, and plants reliant on stable freshwater.

However, increasing tourism pressure has placed strain on this fragile system. For instance, large visitor numbers, littering, and unsupervised access can degrade water quality and disturb surrounding habitats. Human contact with the Blue Eye can introduce pollutants, disrupt sediment balance, and damage underwater structures. To help combat this, swimming restrictions have been introduced to protect both visitors and the ecosystem.

Without careful management, overtourism can be damaging, as visitor numbers may exceed the environment's capacity to recover. Even small ecological changes can accumulate, affecting water clarity and flow stability. Balancing tourism with conservation is now essential to ensure the Blue Eye remains accessible and protected for future generations.

The best time to visit the Blue Eye

We recommend visiting the Blue Eye in the early morning when temperatures are cooler and visitor numbers are lower. Shoulder seasons (the travel period between peak and off-season), such as spring (April–June) and early autumn (September–October), are an ideal time to travel. If possible, avoid visiting at midday in the summer, as this tends to be the busiest period. Planning your trip outside of these peak times not only helps reduce congestion but also supports sustainable tourism.

Experiencing the Blue Eye

With forest surroundings such as shaded trails and greenery, the air is noticeably cooler than nearby lowland areas, particularly in the summer months. The sound of rushing water adds to the immersive experience of visiting the Blue Eye, building anticipation as visitors approach the spring. The water temperature is around 10° Celsius/50° Fahrenheit year-round, which can cause a brief temperature shock when touched!

Access and local facilities

The Blue Eye is accessible via woodland, enhancing the overall visitor experience. Conveniently, you'll find basic facilities nearby such as cafés and refreshment spots, as well as designated viewing points where the spring can be observed safely. Responsible tourism etiquette is important, so don't forget to stay on marked paths, avoid littering, and respect swimming restrictions to protect the fragile ecosystem.

The Blue Eye is a convenient base for exploring nearby cultural highlights. Saranda, a coastal town which can be found along the Albanian Riviera, is only a short drive away. Just south of this is Butrint, a UNESCO-listed destination and one of the greatest archaeological sites in the Balkans.

Stretching along the Ionian coast, the Albanian Riviera gives you a true sense of Albania's incredibly diverse landscape. Inland, mountain villages featuring traditional architecture stand in contrast to beaches and tourist hotspots, showcasing Albania's understated beauty.
