Tunneler
There are 19 tunnels on this route. Most are short, straightforward and sit on very quiet stretches of road. The notable ones are highlighted on the route map. Four tunnels are long enough to feel like a proper event: Sjonatunnelen (2796 m), Silatunnelen (2882 m), Straumdalstunnelen (3200 m) og Storvikskartunnelen (3100 m). You must ride through the first three — there’s no alternative — but they’re surprisingly quiet and almost enjoyable once you settle in. For Storvikskartunnelen, you can take the old mountain road, but in reality, it’s easier and quicker to ride through the tunnel.

The only tunnels I’d call unpleasant are grouped together about 100 km south of Bodø: Skauvolltunnelen (247 m), Vindviktunnelen (980 m) og Sundsfjordtunnelen (772 m). They sit on the RV17, which can have short bursts of traffic depending on ferry arrivals. They’re safe enough, but not exactly enjoyable if you happen to share the tunnel with cars.

Tips: Long tunnels (2–3 km) can be shockingly cold once you’re deep inside. Put on a layer before entering and keep gloves handy;  your fingers will thank you.

Travle veier
There are very few genuinely busy sections on this route. The ferry network naturally regulates traffic: every few hours a convoy of 20–30 vehicles will pass, then the road returns to near-silence. The only stretch that consistently feels a bit unpleasant is that same RV17 section roughly 100 km south of Bodø. Apart from that, the riding is calm.

Været
Summer conditions vary hugely. You can have warm, bright days where the sun never really sets, beautiful, but draining. With 24-hour daylight, tents heat up fast, often turning into ovens by 05:00 or 06:00. Sunscreen is essential from morning to evening. When Atlantic low-pressure systems arrive, temperatures can drop sharply, even in peak summer. Expect cold rain, mist and stubborn headwinds on exposed coastal stretches. Parts of the route are wide open to the sea, so wind direction can make or break your day.
