Exhilaration and/or sheer terror can strike in a Malaga gorge, writes Philipp Laage.
The guide is sympathetic as the walkers head off up one of the scariest hiking trails in the world, telling them his own little secret: "If you're afraid of heights, that's fine. I'm scared of heights too."
The adventurers are walking the Caminito del Rey — the king's little pathway — in Spain's Andalusian province of Malaga. The trail is often billed as "the most dangerous in the world," as falling off its ledges leads to certain death.
After fatalities, it was blocked off from the public for 15 years before being reopened in a safer form in 2015.
The morning autumn air quickly warms the day in southern Spain, and there's a pungent smell of pines. From the car park in the small town of Ardeles, it's about a 30-minute walk to reach the official starting point of the Caminito del Rey. There, each visitor is registered and handed a helmet. Not only can walkers slip, but there is real danger of rocks falling on them.
