Travel Experience
We started climbing almost immediately and it didn’t take long before the scenery turned from green valleys into bare rock and water reservoirs.
At one stop near a dam there were a few cars parked and people mostly just standing around looking down at the water. It felt more functional than scenic, but we still stopped anyway.
There were long stretches of sharp bends where the road clung to the mountainside. We didn’t really talk much, just focused on the driving and the constant change in direction.
We stopped for a quick coffee in a small building that felt more like a utility stop than a typical mountain café. Nothing memorable happened, just a short break from the constant switching between corners.
By the end of the Grimsel Pass, it felt less like a picturesque alpine route and more like a raw mountain corridor shaped as much by engineering as by nature, with water, rock, and road all tightly intertwined.
