The triangle in Trollheimen – why the mountain hike is at the very top of Norway

 

Vast mountain ridges, lush green valleys, historic mountain lodges, and panoramic views that stretch for kilometers. The Trekanten (Triangle) hike in Trollheimen is more than just a classic, it is one of Norway's absolute most popular wilderness adventures.

In the summer of 2025, this spectacular route topped the list on UT.no as the country's most searched hiking suggestion, outperforming iconic destinations like Besseggen, Romsdalseggen, and Galdhøpiggen. By the end of the year, the Triangle secured a phenomenal second place overall.

Yet, it isn’t the top rankings that keep people coming back. It is the unforgettable combination of vibrant valleys, magnificent high-alpine terrain, cozy mountain cabins, and the profound feeling of exploring a landscape steeped in living history.

A journey through the heart of Trollheimen

The classic Triangle route connects three iconic DNT cabins: Gjevilvasshytta, Jøldalshytta, and Trollheimshytta, before looping back to Gjevilvasshytta across the Mellomfjell ridge.

Over the course of three to four days, you will experience some of the most diverse mountain scenery Norway has to offer. The landscape constantly shifts character, transitioning from lush river valleys to wide-open plateaus and distinctive, towering peaks like Snota and Trollhetta.

Trollheimen truly lives up to its name ("The Home of the Trolls")—it is wild, welcoming, and full of striking contrasts.

Living valleys and rich traditions

One of the elements that makes the Triangle so unique is the cultural landscape you traverse along the way.

In the Gjevilvassdalen valley, grazing animals still roam freely during the summer months. In Jøldalen, centuries-old farming traditions are kept alive at the Jølsetra mountain pasture, which remains fully operational during the summer season. Livestock also grazes around Trollheimshytta, maintaining the old ways of life.

Throughout the area, historic farm buildings serve as a beautiful reminder of the generations who lived and worked in these valleys long before the dawn of mountain tourism. It adds a rich cultural dimension to the journey.

Around Trollheimshytta, you will also encounter some of Trollheimen's most magical nature: massive, ancient giant pines that give the old-growth forest an enchanting, otherworldly atmosphere.

Three distinct stages, three unique experiences

Stage 1: Gjevilvasshytta to Jøldalshytta

This first leg is considered the gentlest day of the trek, yet it delivers spectacular scenery. The trail winds past the foot of the Høghøa mountain, crosses the Minilla River, and traverses Skrikhøa before opening up to the stunning, wide landscapes of the Jøldalen valley.

Stage 2: Jøldalshytta to Trollheimshytta

This stage offers the greatest variety of the trip, allowing you to choose between three distinct routes depending on your fitness level and mood:

• The High Peaks: For a demanding and exhilarating day, the route over Trollhetta’s three jagged ridges is the ultimate choice.
• The Panoramic Route: The hike over Geithetta is slightly shorter but still rewards you with incredible high-mountain terrain and breathtaking views.
• The Valley Route: If you prefer a more relaxed day, follow the trail through the lush Svartådalen valley. The path runs along a crystal-clear river, offering idyllic picnic spots and the perfect opportunity for a refreshing dip on a warm summer day.

Stage 3: Trollheimshytta to Gjevilvasshytta

The final leg returns over the Mellomfjell ridge. While it is a demanding day with a fair share of elevation gain, it is also one of the most spectacular. For most of the day, you will hike through open, high-alpine terrain with majestic, panoramic views in every direction.

Mountain cabins with history in the walls

The authentic atmosphere of the DNT cabins adds an extra layer of magic to the Triangle.

Trollheimshytta, built in 1890, is one of the oldest tourist lodges in the region. Jøldalshytta (1917) sits nestled in a classic alpine pasture, while Gjevilvasshytta boasts a history that stretches back even further, the timber in the oldest parts of the building dates all the way back to 1739.

Protected by the Directorate for Cultural Heritage, Gjevilvasshytta has previously been voted Norway’s most beautiful serviced DNT cabin.

After a long, rewarding day on the trail, arriving at a warm lounge, a hot shower, a drying room, and a delicious homemade dinner served by welcoming hosts makes all the difference. It is this complete experience that hikers highlight when explaining why the Triangle is a trek they will never forget.

An extra day you won't regret

Many hikers choose to book an extra night at Trollheimshytta to tackle the summit hike to Snota (1,668 masl). This peak is widely considered the ultimate symbol of Trollheimen.

On a clear day, the summit rewards you with endless views far beyond the surrounding mountain ranges, making it a definitive highlight of the entire journey.

Why people return

Norway is home to countless incredible mountain hikes. Yet, there is a distinct magic to the Triangle in Trollheimen that keeps hikers returning year after year.

It is found in the contrasts. The seamless blend of vibrant valleys and raw, magnificent peaks. The historic cabins with centuries of stories in their timber walls.

And the deep connection to the nature and traditions that still thrive here. For many, completing the Triangle is just the beginning of a lifelong love affair with Trollheimen.
