Outside, it’s 20°C and rising, but I’m in the heart of a mountain and shivering in my shorts. I’m on a newly launched experience in the northern Italian region of Trentino, learning how the apple harvest, cheese, and even a data centre is kept chilled in a vast cave complex.

“In here we have a steady temperature of 10°C all year.” The voice of Eva, my guide, echoes off the tunnels’ high ceilings.

The offbeat, hour-and-a-half in the Heart of the Dolomites tour (£19pp; visitvaldinon.it) was launched in April by Melinda – the consortium that oversees apple production in Trentino’s Val di Non.

The tour has already attracted thousands of visitors from Italy and Europe, including Italian Prime Minister Giorgia Meloni. However, I can’t help glancing over my shoulder at the glowing circle of sunlight at the tunnel’s entrance, yearning for the surface.
