Where is Peña Angulo?

Okay, picture this: Burgos, Spain. You're up in Castile and León, practically spitting distance from the Basque Country. We're talking Peña Angulo, a mountain pass topping out at 735 meters (2,411 feet).

Now, there *used* to be this killer old road, part of the BU-550, snaking its way through here. For ages, it was the lifeline connecting the Basque region to Burgos. Think gorgeous scenery, but also… constant rockfalls and seriously sketchy slopes. Like, edge-of-your-seat stuff.

Eventually, they wised up and built a safer, modern bypass with a tunnel in the early '90s. Smart move! The old road? Officially closed. Blocked off with mounds of earth and plenty of warning signs.

But here's the thing: that abandoned stretch is only about a kilometer long. It starts in a shaded forest and then BAM! You're clinging to the side of a gorge, the views are insane. You can see where they tried to reinforce things with stone walls and bolts. Thing is, chunks of the pavement have collapsed, and in one spot, half the road is just GONE. Old guardrail bits, missing signs, and broken asphalt mark the end of the line, right before the new tunnel.

Basically, it's a snapshot of a road battling nature... and losing.
