F333 (Haukadalsvegur) is a scenic journey located in the Southern Region of Iceland. It's only suitable for 4x4 vehicles with very high ground clearance: along the way there is a small river crossing a few km north of the Haukadalskirkja Church.
The road runs from Road 35 towards F338 (Skjaldbreiðarvegur), a road along powerlines. 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. Expect large potholes, many ruts and large boulders on their surface. Next to the very popular Geysir geothermal area, this road is not for people that are afraid of heights. Driving in a small passenger car is simply and plainly irresponsible and can be very dangerous.
Located in the central Highlands, in a sparse but beautiful forest, 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. The drive offers breathtaking landscapes. It’s one of the famous F Roads of the country.
