Fairly large rest hut with a fireplace and toilet. It needs a broom, though.

Directly at the large sinkhole with the waterfall, a staircase leads down into the cave. After a few meters, however, standing is no longer possible. From here on, the cave may only be entered with a guide. Tours are currently available on Tuesdays and Saturdays. A phone number is posted on the information board at the parking lot. The price is 1,200 kroner.

Beautiful walk with starting point along the famous Vildmarksvägen at the Ankarvattnet. You mainly walk on boardwalks until you reach the waterfall. The water disappears into the cave system and here is also the entrance to the famous Koralgrottan. The cave system is almost six kilometers long and also the longest in Sweden. It is NOT allowed to enter the cave without an experienced guide. This is only possible in the summer period. A few minutes further up there is a hut with barbecue facilities where you can perfectly rest.

A very welcome rest stop. It blends in perfectly with the surroundings. Please take your trash with you after your rest.

A hike almost entirely on wooden planks is worthwhile because of the very beautiful waterfall, even without a guide and direct access to the cave.

At six kilometers long, the Coral Cave is Sweden's longest known underwater cave: it covers 26 square kilometers of narrow passages, enormous cave halls and there is even a waterfall at the entrance. The cave can only be entered during the summer months as part of guided tours.

Bjurälven is renowned as Scandinavia's largest karst landscape, offering a truly distinctive hiking experience. You'll encounter geological formations like crater-like pits, a partially underground river known as the "invisible river," and the wide, treeless Blinda Dalen. The high lime content in the soil also supports a diverse and beautiful array of flora.
There are 5 hiking trails available in Bjurälven, ranging from easy to moderate difficulty. These routes have been explored by over 500 hikers using komoot.
Yes, Bjurälven offers routes for various abilities. For an easier walk, consider the View of the River – Path to Korallgrottan loop from Korallgrottan, which is 6.8 km long. Moderate options include the Lillälven Shelter – View of the Coloseum Valley loop from Bjurälven, a 10 km trail exploring the karst landscape.
Hikers can explore the dramatic karst landscape with its unique pits and formations. A major highlight is the Bjurälven river itself, known as the "invisible river" because it flows partially underground, sculpting gorges along its course. The Bjurälven Grotto is where the river disappears, and the distinctive Blinda Dalen (Blind Valley) is also a notable feature.
A common starting point for hikes into the karst area is from the parking lot at Leipikvattnet farm. From there, marked trails lead directly into the nature reserve.
The region is quite remote, and direct public transport options to the Bjurälven Nature Reserve are limited. It is generally recommended to travel by car to reach the main parking areas and trailheads.
The best time to hike in Bjurälven is typically during the warmer months, from late spring to early autumn, when the trails are clear of snow and the unique flora is in bloom. This allows for optimal exploration of the karst landscape and river features.
Yes, some trails are suitable for families. The area features constructed bridges, boardwalks, and stairs to make navigation easier. An easy route like the View of the River – Path to Korallgrottan loop from Korallgrottan could be a good option for families.
Bjurälven is a nature reserve, and while dogs are generally permitted on trails, they must be kept on a leash to protect wildlife and other visitors. Always check local regulations at the trailhead for any specific seasonal restrictions.
There is a rest cabin at Lillälven, approximately 3 kilometers into the main hiking trail that follows the Bjurälven river. This provides a convenient spot for a break during your hike.
The area is highly rated by the komoot community, with an average score of 4.7 stars from over 100 reviews. Reviewers often praise the unique geological formations, the fascinating 'invisible river,' and the well-maintained trails that allow access to this special natural environment.
