Pounamu was more than decoration. In Maori culture, greenstone carried spiritual authority - it was used for weapons, tools, and ornaments that marked rank and connection to the land. The West Coast rivers where it was found lay on the far side of the Southern Alps from the Canterbury settlements, making the mountain passes vital arteries of trade and cultural exchange. Lewis Pass, as the northernmost of the three main crossings, connected the Ngai Tahu communities of Canterbury with the pounamu sources in the Maruia and Grey River catchments. The route demanded fitness and knowledge of the mountains - alpine weather in this part of the Southern Alps is notoriously fickle - but it was lower and gentler than Arthur's Pass to the south, making it the preferred crossing for traders carrying heavy loads of stone.

Henry Lewis was working for the Nelson Provincial Survey Department when he and Christopher Maling crossed the pass in 1860. Their documentation opened the route to European use, though it would be decades before a proper road followed. State Highway 7 now traverses the pass, but the road was not officially opened until 30 October 1937 - seventy-seven years after Lewis's survey. That long gap speaks to the difficulty of building through this terrain and the lower priority given to this northern crossing compared to Arthur's Pass, which connected directly to Christchurch. For years, a regular bus service carried passengers over the pass, linking the West Coast to Canterbury via Waipara. That service has since been replaced by a seasonal shuttle operated in conjunction with East West Coaches, a reminder that even in the twenty-first century, crossing the Southern Alps remains a logistical challenge shaped by weather, distance, and small populations.

What distinguishes Lewis Pass from the other main alpine crossings is its forest. The highway passes through extensive stands of unmodified native beech - Nothofagus species that have grown here since before human settlement. Unlike much of lowland New Zealand, where logging and pastoral farming stripped the original bush, the forests around Lewis Pass survived intact, their remoteness and the difficulty of the terrain serving as protection. The Lewis Pass National Scenic Reserve, gazetted in 1981, now safeguards this canopy. Walking through these beech stands feels like entering a building: the trunks rise in columns, the canopy closes overhead, and the understory dims to a green half-light filtered through millions of small, rounded leaves. In autumn, red beech turns the hillsides copper and bronze. In winter, snow loads the branches until they creak. The short Alpine Nature Walk near the summit saddle loops through an alpine wetland and tarn, offering a taste of the high country without demanding the commitment of longer tramping routes like the St James Walkway.

Lewis Pass lacks the drama of Arthur's Pass and the coastal grandeur of Haast Pass, and that is precisely its appeal. At 907 meters, it sits between the two in elevation - slightly lower than Arthur's Pass, higher than Haast. The small spa settlement of Maruia Springs lies just over the saddle on the West Coast side, offering hot pools fed by natural mineral springs. The pass serves as an alternative route between Christchurch and Nelson, avoiding the ferry crossing at Picton or the longer coastal drive. Drivers who choose it find a road that winds through river valleys and forested gorges without the white-knuckle switchbacks of SH73. The traffic is lighter. The scenery is quieter but no less beautiful - a landscape of deep greens, river stone, and mountains that recede in soft blue layers to the horizon. For those who prefer their Southern Alps without crowds or adrenaline, Lewis Pass delivers.
