Tremola (the historic switchback road) on Passo del San Gottardo is a dramatic serpentine climb with stone walls, hairpin turns, and moody mountain skies. Photograph the road layers disappearing into fog or sunlight; winter snow and autumn larches add strong seasonal drama. Access is straightforward by car from Airolo; check road closures and weather at the pass.
