Deep within the majestic Lyngen Alps of Northern Norway lies a natural wonder that feels plucked straight from a fairy tale: Blåvatnet. Often referred to as Norway’s hidden blue lake, this glacial basin is famous for its impossibly bright, neon-turquoise water that contrasts sharply against the jagged, dark peaks of the surrounding mountains. For hikers and outdoor enthusiasts, reaching this remote location is a bucket-list experience that rewards physical effort with scenery that defies belief. In this guide, we will explore everything you need to know about trekking to this shimmering jewel of the North.
The Geological Wonder of Blåvatnet

What makes Blåvatnet stand out from the thousands of other lakes in Norway is its unique, electric blue color. This phenomenon is not magic, but rather the result of glacial flour—finely ground rock particles created by the movement of glaciers against bedrock. As the glacier melts, these particles flow into the lake, remaining suspended in the water column. When sunlight hits these particles, the water absorbs all other light colors and reflects back a stunning, vibrant blue that remains vivid even on overcast days.
The Source of the Color
The water quality at the lake is pristine, sourced directly from the Lenangsbreen glacier located at the head of the valley. Because it is fed by glacial melt, the water remains incredibly cold throughout the year, even in the height of summer. The combination of the sheer mountain walls, the retreating ice, and the silent valley floor creates an atmosphere of deep tranquility that visitors rarely forget.
Planning Your Journey to the Lyngen Alps

Getting to the starting point of the trail requires some logistical planning, as it is located in the beautiful, rugged region of Troms. Most travelers base themselves in Tromsø, the largest city in Northern Norway, before heading east toward the Lyngen Peninsula. You will need to take a ferry, usually from Breivikeidet to Svensby, to reach the heart of the Lyngen Alps.
Getting There from Tromsø
Once you arrive in the Lyngen area, you should drive toward the village of Lenangsbotn. The trailhead is easily accessible by car, with a designated parking area located near the end of the public road. It is highly recommended to rent a car, as public transportation options in the remote valleys can be limited and infrequent, which might leave you stranded if you do not time your return perfectly.
The Hiking Trail: What to Expect

While the hike to Blåvatnet is not considered an extremely technical climb, it is certainly a challenging trek. The route is approximately 8 to 10 kilometers round-trip, depending on the exact starting point and your path choices. The terrain consists largely of a rocky moraine, which requires a good sense of balance and sturdy hiking boots.
Terrain Difficulty
The first part of the trail follows a fairly flat path through the valley, offering pleasant views of the surrounding flora. As you get closer to the lake, the landscape becomes much rockier, and you will find yourself navigating large boulders and loose gravel. This section demands careful foot placement, especially if there has been recent rain, as the rocks can become slippery.
Safety and Preparation Tips

Safety is paramount when hiking in the Norwegian wilderness, especially in a region as wild as the Lyngen Alps. Even in summer, the weather in the mountains can change in a matter of minutes. You might experience bright sunshine one moment and a cold, driving rain the next, so dressing in layers is absolutely mandatory for a successful trip.
Essential Gear Checklist
- Sturdy, waterproof hiking boots with ankle support.
- A windproof and waterproof outer shell jacket.
- A base layer made of moisture-wicking wool or synthetic material.
- A navigation app or paper map, as GPS can sometimes be unreliable in narrow valleys.
- Sufficient water and high-energy snacks for the day.
- A first-aid kit, including blister plasters for the long rocky sections.
It is also wise to inform someone of your planned route and expected return time. While the trail to Blåvatnet is marked, it is not an “easy” stroll, and fatigue can set in quickly when navigating the boulder fields.
The Best Time to Visit
Timing your visit to Blåvatnet is essential to getting the full experience of the lake’s color. The ideal window for this hike is between late June and early September. During these months, the snow has mostly melted from the valley floor, making the trail accessible without needing specialized snow gear or crampons.
Mid-Summer vs. Late Season
Visiting in July provides you with the benefit of the Midnight Sun, allowing you to hike at 10:00 PM in broad daylight if you wish to avoid crowds. If you prefer a more autumnal atmosphere with crisp air and fewer hikers, late August and early September are perfect. Be aware that as winter approaches, the sun sets rapidly, and the temperatures drop well below freezing, even during the daytime.
Capturing the Beauty: Photography Advice
Photography enthusiasts will find endless opportunities at Blåvatnet. To capture the true blue of the water, try to use a circular polarizer filter on your lens; this will reduce glare on the surface of the water and make the turquoise tones pop even more against the dark rock.
Finding the Best Angles
Don’t just stay at the edge of the lake where the trail ends. Walk along the shoreline to find different perspectives. Getting low to the ground near the water’s edge can create a powerful foreground, especially if you can capture the reflection of the surrounding peaks in the still, blue water.
Respecting the Nature of Norway
Norway operates under the “Allemannsretten,” or the Right of Public Access, which allows everyone to explore the wilderness. However, with this right comes the responsibility of “Leave No Trace” ethics. Because the ecosystem around Blåvatnet is fragile, it is vital that you carry out everything you carry in.
Why Conservation Matters
The vegetation in this high-altitude region grows very slowly. Stepping off the marked path can damage delicate mosses and flowers that might take decades to recover. Stay on the marked trail, do not disturb wildlife, and ensure that your visit leaves the landscape exactly as pristine as you found it for the next hiker to enjoy.
Conclusion
Blåvatnet is more than just a destination; it is a testament to the raw, untamed beauty of Northern Norway. Whether you are seeking a challenging hike, a stunning photography subject, or simply a quiet moment in nature, this hidden blue lake provides an experience that stays with you long after your boots are cleaned and your bags are unpacked. If you find yourself in the Troms region, prioritize a day for this incredible trek. Pack your gear, respect the wilderness, and get ready to witness one of the most remarkable natural sights in all of Scandinavia. Start planning your Norwegian adventure today and put the magical Blåvatnet at the top of your list!
