Why You Might Encounter River Crossings in Iceland

Iceland is famous for its stunning natural wonders, from cascading waterfalls to geothermal hot springs. Many of these awe-inspiring sites are located off the main roads, accessible via Iceland's "F-Roads"–mountain tracks winding through some of the country’s most remote landscapes. These paths often require drivers to cross rivers to reach their final destination.

For instance, a visit to the renowned Landmannalaugar area in the Icelandic Highlands will often take you across shallow rivers. Similarly, journeys to Þórsmörk or the remote Askja Caldera require traversing river crossings as part of the adventure. Equipped with the right vehicle and knowledge, these tasks become not only manageable but thrilling.

What You Need to Know Before River Crossing

1. Rent the Right Car

When renting a car in Reykjavík, Iceland, choose a 4x4 vehicle specifically designed for highland road conditions. Many standard cars or small SUVs are not equipped to handle river crossings or rugged terrain, and attempting to cross in an unsuitable vehicle can lead to damage or dangerous situations.

Pro Tip: Look for rental options specifically marketed as F-road-approved, such as rugged Land Cruisers or Defenders. Rental providers like Höldur often feature vehicles explicitly tailored for Iceland’s unique environment.

2. Assess the River Depth

Not all rivers in Iceland are the same. Some can be shallow and easy to cross, while others are wide and fast-flowing, requiring serious caution. To gauge whether it’s safe to drive through a river, park your vehicle and observe the water’s movement. Fast-running water is typically more challenging. Use landmarks, such as rocks or foliage, to visually estimate the depth.

If still unsure, you can walk into the river (only if it’s safe to do so) to test the depth and current strength. Be cautious, as cold water and slippery rocks can pose additional risks.

3. Check Road Conditions in Advance

Before heading into the wilderness, visit Iceland’s official road condition website (www.road.is) or review updates from the Icelandic Road and Coastal Administration. Certain F-roads or river crossings may be closed depending on seasonal weather or recent conditions.

It’s also helpful to ask locals, such as park rangers or rental car professionals, for the latest advice and tips.

How to Safely Cross Rivers in Iceland

Step 1. Stop and Assess the Situation

When approaching a river, never rush into a crossing. Stop your vehicle at a safe distance and assess the terrain, current, and depth as mentioned earlier. Check for signs of other crossings and examine tire tracks left by other vehicles to gauge the safest path.

Step 2. Engage Low Gear and Drive Slowly

Select low-range gear (L or 1) if your 4x4 vehicle allows it. This will give you more control and power when navigating uneven terrain. Enter the water at a slow and steady pace. Avoid accelerating too quickly, as this can create unnecessary waves and increase water resistance.

Step 3. Cross Diagonally and Downstream

Drive diagonally across the river, heading slightly downstream. This technique reduces the amount of water resistance pushing directly against the front of the vehicle. Keep a steady speed without stopping in the middle of the river.

Step 4. Avoid Deep Patches in the River

Keep an eye out for deep hollows or dips in the riverbed. The clearest water generally indicates shallower patches, whereas dark areas may be deeper.

Step 5. Exit Slowly and Check Vehicle Condition After Crossing

Once you’re clear of the river, drive a short distance before stopping to check your vehicle. Look underneath for any potential damage caused by water pressure or debris.

FAQ About Driving Safely in Iceland

Do I need a permit to drive on F-roads in Iceland?

No, but you need a four-wheel-drive (4x4) vehicle, as driving on these roads in regular cars is illegal and unsafe.

Not necessarily. Some rivers are too wide or turbulent for safe crossing. Avoid crossing during heavy rain or after sudden glacial melts.

Should I trust GPS routes that lead to river crossings?

Always cross-check GPS routes with reliable road guides and updates from www.road.is. GPS systems may sometimes recommend risky or unverified paths.

What should I do if my car gets stuck in the river?

If your vehicle stalls in the water, never attempt to restart the engine immediately, as this can flood the engine. Call emergency services or your rental car provider for assistance.

What time of year is best for river crossings in Iceland?

The summer months (June to September) are ideal for driving on F-roads since rivers are usually at their shallowest after the snowmelt stabilizes.

What about vehicle insurance and river crossings?

Damages caused by driving in or across rivers or any kind of waterways is not covered by any insurance. Such driving is totally the responsibility of the renter.
