Introduction

The Spiral Tunnels are a railway engineering wonder built by the Canadian Pacific Railway to conquer the steep grade of the Kicking Horse River valley. Two tunnels spiral inside the mountain in a figure-eight, letting trains climb or descend in a corkscrew to cross the rugged canyon safely. From the dedicated viewpoint you can see a single train appear at two different heights at once — a must-see for Rockies railway enthusiasts.

✨ Highlights

Train appears twice

The viewpoint faces the tunnel mouths; with luck you see one train at two heights at once.
