Sonfjället is not only one of Sweden's oldest national parks, it is a symbol of the untouched Härjedalen. As you approach the massif, you will see its characteristic, round silhouette dominating the horizon long before you reach the park boundary. This is a landscape shaped by the ice sheet, characterized by vast boulder fields, lichen-covered mountain heaths and one of the country's densest bear populations.
Hiking here requires a different approach than in the more accessible tourist resorts. Here, nature's conditions apply. The terrain is rocky, the weather changes without warning, and the encounter with the wilderness is more tangible. For the prepared hiker, Sonfjället offers one of the most authentic mountain experiences in the southern mountains.
The Bear's Kingdom – Myths and Pragmatic Security
Many visitors come to Sonfjället with a mixture of fascination and concern for bears. It is true that the area is one of Sweden's most bear-dense, but the chance of actually seeing a bear during a day hike along the marked trails is small. The bear is a shy animal that has usually heard or smelled you long before you even suspect its presence.
From a pragmatic perspective, safety in bear country is about common sense rather than drama:
- Make noise: You don't have to scream, but a normal conversation or the sound of hiking poles against rock is enough to not surprise an animal.
- The dog on a leash: This is non-negotiable. A loose dog running up to a bear and then running back to its owner is the most common cause of problematic encounters.
- Cooking: If you are camping, keep cooking away from the tent and store food tightly. The inhabitants of nature should not get used to people being food.
Respect for wildlife is part of the charm of Sonfjället. Knowing that you are walking in an area where predators actually live gives the hike a nerve that is missing in many other parks.
Strategic starting points and leadership choices
Sonfjället offers everything from short family trips to demanding full-day projects. The choice of starting point determines the character of your day.
Nyvallen – The living shack
Nyvallen is the most popular starting point and one of the few places where you can experience an active fäbod culture. Several of the classic trails start from here.
- Lillfjället (4 km): An excellent "introductory" hike for those who want to experience mountain terrain without investing a whole day. The views are rewarding in relation to the effort.
- The summit hike: From Nyvallen, the trail goes steeply up towards the highest point of Sonfjället (1,278 m above sea level). It is a physically demanding hike that requires good fitness and stable shoes as the surface often consists of loose stones and boulders.
Nysätern and Dalsvallen
For those looking for a little more privacy, Nysätern or Dalsvallen are good alternatives. From here you can quickly reach the central parts of the massif and can plan longer tours that take you around the entire mountain (about 18–20 km). Such a tour gives a complete picture of the park's variety, from the lush mountain birch forests to the barren, high-alpine environments of Södödalen.

Equipment Strategy: Function Over Trends
When packing for Sonfjället, you should start from a hierarchy of importance. It's easy to get caught up in the details of small things, but in the mountains, it's the big choices – the "big three" (tent, sleeping bag, backpack) and your shoes – that determine whether the trip will be a success or a trial.
The mountains rarely punish those who pack logically. A backpack with the correct carrying system and good ventilation against the back is crucial when climbing the steep slopes from Nyvallen. If the pack starts to sway or press incorrectly, the hike becomes unnecessarily tiring and the focus shifts from nature to your own pain.
Footwear and protection in rocky terrain
The terrain in Sonfjället is notorious. Large parts of the trails go over boulder ground – areas covered with rocks of varying sizes. Here, light trail shoes are often a risky choice for the unaccustomed. A stable boot with a torsionally stiff sole provides the support the ankle needs when the rock underfoot moves.

A detail that is often forgotten but is invaluable in the Härjedalen terrain is a pair of sturdy gaiters. Even if it is sunny, the ground can be wet and muddy in the lower forest areas. Gaiters not only protect against moisture but also prevent gravel and small stones from finding their way into your boots during the rocky sections. It is a simple accessory that significantly increases your comfort during a full day's hike.
Sleep is your most important recovery
If you plan to spend the night in the national park, your choice of tent and sleeping bag will be critical. The peaks of Sonfjället do not protect against the wind; on the contrary, it can whip through the valleys. A stable mountain tent with a low profile is preferable to taller structures that trap the wind.

When it comes to insulation, there is a constant trade-off between weight and warmth. Many people today choose lightweight down sleeping bags to keep the weight down in their backpacks, which is wise as long as you understand what you are buying. The quality of the down (CUIN) and the down to feather ratio determine how effectively the bag traps heat.

Remember that ground chill (cold that rises from the ground) is often the biggest culprit in a bad night's sleep. A good sleeping pad is as important as the sleeping bag itself. Without recovery, the next day's climb will be significantly harder.

Safety and mountain logic
The weather at Sonfjället can change in minutes. A clear blue morning can quickly turn into fog and strong winds. Mobile phones don't work everywhere here, and blindly relying on GPS apps is a beginner's mistake. A map and compass should always be with you and you should know how to use them before visibility disappears.
Ask yourself before the trip: What is the worst that can happen and do I have the equipment to handle it?
- If I sprain my foot: Do I have extra clothes to keep warm while I wait for help?
- If the fog comes: Can I navigate back without seeing the trail?
- If the rain is pouring: Will my shell clothes keep me dry enough to avoid getting chilled?
Closing Thoughts: The Balance Between Lightweight and Safety
Hiking in Sonfjället is a lesson in humility. It's a place where you quickly realize that trendy gear means little if it doesn't work when the clouds roll in. Aim to pack light, but never compromise on safety or your ability to get a good night's sleep.
When you stand there at the top and look out over the endless forests and mountains of Härjedalen, knowing that the bears are moving somewhere down in the valley, then you understand why Sonfjället is so special. It is true wilderness – raw, beautiful and absolutely wonderful for those who are well prepared.
Plan your trip, double-check the map and make sure your equipment is ready for the task. The mountain awaits.
