The Blue Eye of Theth (Syri i Kaltër) is one of the valley's most rewarding walks — an intensely blue karst spring pool hidden in a forested gorge down the valley. This is a complete guide to reaching it, what to expect, and one important thing to get straight before you go. For the valley's other walks, see our best-hikes guide.
First: which Blue Eye?
There are two Blue Eyes in Albania, and they are often confused. This one is the Blue Eye of Theth, a spring pool in the Theth valley in the Albanian Alps. It is a completely different place from the far better-known Blue Eye near Sarandë in southern Albania. If you are in Theth, you cannot pop down to the southern one — they are at opposite ends of the country. This guide is about the Theth Blue Eye.
What it is
The Blue Eye is a karst spring — the intense blue colour comes from the depth and clarity of the water welling up through the rock. It sits along the Black River drainage, reached from the hamlet of Nderlysa down the valley. The draws are the vividly blue pool, the little waterfall that feeds it, and the clear stream running through the gorge. Some visitors brave a swim in the icy water — but it is genuinely cold, so most just look. The forested walk in is part of the experience.
How to get there
Most people reach the trailhead at Nderlysa first, then walk the final stretch — you cannot drive all the way. Practical points:
- Get to Nderlysa about 7 km down the valley — 15–20 minutes by car, or by shared minibus from Theth (~20 minutes, around €5 each way); ask your guesthouse to arrange a seat.
- From the Nderlysa car park it is a walk of about 40–50 minutes to the pool — roughly 2 km, and steep uphill in places — on rough mountain paths, so carry water and wear sturdy shoes.
- If you drive, a small parking fee applies at the Nderlysa trailhead (around 150–200 LEK / €2, cash); the Blue Eye itself is open access and free, deep in nature with no facilities.
- With the transfer, the walk and time at the pool, it makes a relaxed half-day outing — start earlier if you want it quieter.
When to go & tips
Like the rest of the valley, the Blue Eye is a summer outing (roughly June–September), when the trails are clear and guesthouses are open — see our best-time-to-visit guide. Start early for the walk, bring layers and water, and check conditions with your guesthouse before setting out; mountain weather changes fast. For how to reach the valley itself, see our getting-to-Theth guide, and our practical info for what else to pack.
