Iceland is known for its breathtaking landscapes, winding gravel roads, and countless rivers that must be crossed to reach some of its most remote locations. However, one river stands out as particularly treacherous: Krossá, the final major crossing on the route to Þórsmörk. Many experienced drivers, tour guides, and locals strongly warn against attempting this crossing due to its unpredictable nature. If you are planning a trip to Þórsmörk, here's everything you need to know about Krossá and the safer alternatives available.
Krossá is not just any river crossing; it is one of the most dangerous in Iceland. Unlike smaller rivers you might encounter on the way to Þórsmörk, Krossá is deep, fast-flowing, and has an unstable riverbed. The current can be strong enough to sweep vehicles away, and the depth varies drastically depending on recent rainfall and glacial melt. Even experienced drivers have found themselves in trouble here, with multiple incidents of cars being stranded, overturned, or even lost to the river.
The safest way to visit Þórsmörk is to park before Krossá and use the pedestrian bridge. This allows you to explore the area without risking your vehicle. There is a designated parking area just before the river, where many hikers and visitors leave their cars before crossing on foot.
If you want to avoid river crossings altogether, taking a highland bus is a great option. These buses are operated by companies specializing in Iceland’s rugged terrain and use large, high-clearance vehicles designed for river crossings. They depart from Reykjavik, Hella, and other key locations, providing an easy and stress-free way to reach Þórsmörk.
For those looking for an adventure but lacking a suitable vehicle, Super Jeep tours offer a safe way to experience Iceland’s highlands. These specially modified vehicles, driven by experienced guides, can handle deep river crossings and rugged terrain with ease.
Even before reaching Krossá, there are several deep and challenging river crossings along the F249 road leading into the valley. These should not be underestimated. The difficulty of each crossing depends on recent weather, water levels, and your vehicle’s capability.
Not all 4x4 vehicles are suitable for Icelandic river crossings. If you plan on driving into the highlands, including towards Þórsmörk, you should have:
For most travelers, the answer is no. Crossing Krossá is highly risky, even for experienced drivers with the right vehicle. With a convenient footbridge, highland buses, and Super Jeep tours available, there’s no real reason to put your vehicle (or yourself) in danger. Instead, enjoy a stress-free trip to Þórsmörk by choosing one of the safer alternatives.
Iceland’s rivers can be unpredictable and unforgiving, but with proper planning and smart decisions, you can still experience the magic of the highlands safely. If you’re ever in doubt, don’t risk it—take the bridge, the bus, or a guided tour instead!
