[Countrywide] Tunnels as attractions: which long/undersea/unusual tunnels are actually fun (or mind-blowing) to experience?

[EIA_Ask_NO]

Some tunnels are so long, deep, or unusual that they become an experience — but visitors also worry about comfort and safety (especially if you’re not used to long tunnels).

If you recommend one, please share:

• What makes it special (length, undersea depth, design/lighting, “this feels unreal”)
• Driving reality: steep grades, ventilation feel, traffic, stress level
• Any nearby safe stop to rest before/after
• Tips for nervous drivers (music/offline maps, breaks, timing, staying calm)
• Anything to watch for (speed controls, sudden weather outside, queues)

Which tunnel felt the most memorable — and what advice would you give a first-timer?

For tunnels as attractions, the Lærdal Tunnel is the one that genuinely messed with my sense of reality in a good way, mostly because it just keeps going and then politely changes color like you’re inside a Scandinavian screensaver. From what I’ve seen, driving it is surprisingly calm—wide lanes, steady grades, decent ventilation—and the lit caverns give your brain a break before it spirals into “how am I still underground?” mode. I stopped before and after just to reset, which I’d recommend if long tunnels make you tense, and downloading music is non-negotiable unless silence is your coping strategy. Am I the only one who found this weirdly enjoyable, or did someone else have a tunnel experience that was even more mind-bending?

The tunnel that really messed with my sense of scale was the Lærdal Tunnel. Driving into it feels normal for the first few minutes, and then you realize you’re still underground… and still underground… and it just keeps going. What makes it fun rather than stressful are those blue-lit caverns where you can mentally reset — they genuinely help with fatigue. The grades are gentle, traffic is calm, and ventilation never felt claustrophobic to me. I pulled over in Lærdal afterward just to stretch and let my brain recalibrate. My tip for first-timers is simple: put on familiar music, don’t rush, and trust the engineering. Are you hitting it as part of a fjord route, or just using it to save time between regions?
