The single most common packing mistake on any of our three routes has nothing to do with clothes people forgot — it’s clothes people brought too much of, in the wrong form, for a day that’s actually going to swing 15-20 degrees Celsius before dinner.
Why the swing is bigger than people expect
A day that starts at sea level or a resort pool and ends at 2,500+ meters isn’t a gradual transition — on Timmelsjoch, Grossglockner, or Teide, the climb happens over a couple of hours, and the temperature drop tracks it closely. Base-of-the-mountain shorts weather can become genuinely cold, windy conditions at a summit viewpoint within the same drive, and the return descent reverses the whole thing just as fast.
Layers, not one heavy coat
The single biggest upgrade over a first-timer’s instinct: a breathable base layer, a packable mid layer (fleece or a light sweater works better than something bulky you can’t easily remove in the car), and a wind- and water-resistant outer shell. This combination covers a 20-degree swing without ever requiring the one thing a single heavy coat forces on you — either wearing it uncomfortably at the base or leaving it behind and regretting it at the summit. All three layers, folded, take up less trunk space than one proper winter coat.
Footwear matters more than people expect
A firmer-soled shoe gives noticeably better pedal feel in a high-performance car than the average sneaker most people default to for travel — not essential, but a real, felt difference on a technical mountain road where fine throttle and brake control actually matters. Pack one pair specifically for driving days if you have them; regular travel shoes are fine for everything else.
Sun protection at altitude, not just at the beach
UV exposure increases meaningfully with altitude, and it’s easy to underestimate on a driving day since the car’s windscreen and the cooler air both mask how much sun exposure is actually happening. Sunglasses matter more at a 2,500-meter summit than they do at sea level, and sunscreen is worth applying even on a day that starts overcast at the base.
Gloves, even in summer
If your route includes a high pass and you’re driving with the roof down, a light pair of driving gloves earns their trunk space — not for grip on a dry road, but for the wind chill at altitude that a bare hand feels far more than the rest of the body does inside a jacket.
What not to overpack
Beyond the layers above, resist the instinct to bring a second heavy jacket “just in case” — the layering system covers the realistic range, and most of our routes’ luggage space, particularly in the two-seat exotic fleet, is genuinely limited. A weekend bag that closes properly matters more on a driving tour than it does on almost any other kind of trip.
This kind of temperature swing is a real feature of the Porsche Europe Road Trip, the Supercars Rally Monaco’s Col de Turini day, and the Mustangs Tenerife’s Teide crossing. Get in touch if you have questions about what to pack for your specific route.
