F235 (Langisjór) is a very dangerous drive located in the south of Iceland. It's only suitable for 4x4 vehicles with very high ground clearance. There are a number of small streams that need to be crossed.
The road is 25.4 km long. It runs from F208 road to the majestic long deep glacial lake Langisjor. It’s among the clearest highland lakes in the country but hardly known due to its remoteness and notoriously barren climate. It is a rough and challenging road only for a 4 wheel drive vehicle with high clearance. The track is pretty bad, it's not rolling with a lot of big rocks. Driving in a small passenger car is simply and plainly irresponsible and can be very dangerous. If you are comfortable crossing the river at the beginning of the road, the rest of the route is rough in spots but straightforward.
Located in the midst of the Icelandic Highland, within the Vatnajokull National Park, the road is surrounded by lunar landscapes, and is pretty bumpy. It’s only open during the summer months, usually between late June and early September. Expect to be alone, this track is not very busy. It is not recommended to drive unaccompanied. In case of a breakdown, there is very little in the way of passing traffic or inhabitants around, and no cell phone service in parts. It’s one of the highest roads of the country, climbing up to 686m (2,250ft) above the sea level.
Along the route you’ll need to cross a number of small streams. Crossing big rivers requires a bit of experience. Do not attempt to cross with one car, or during heavy rain. It can be treacherous if the water level rises due to lots of rain and warm weather. Only well equipped jeeps and larger vehicles are able to cross the rivers. Please do not attempt to cross this river on a small jeep. This river is not considered safe for anyone but very experienced drivers, that know this river and only in very high ground clearance super trucks. In case you get stuck in the river, call 112. Always check the river to ensure that it's not too deep. Rivers that can change rapidly with rain or change in heat. This road is amazing by day, but can be dangerous during the dark night. Rental car insurance does not cover damages from water, including any damage caused by crossing rivers. It’s one of the famous F Roads of the country.
