Christchurch to Greymouth over Arthur’s Pass by Campervan

Quick summary: Arthur’s Pass is the shortest and most dramatic campervan and motorhome route across the Southern Alps, linking Christchurch with the West Coast in around 240 km. It crosses the Canterbury Plains, climbs through high-country stations and the giant limestone boulders of Castle Hill, reaches the alpine village of Arthur’s Pass in the heart of a national park, then plunges down the steep Otira side to the rainforest and rivers of the West Coast. It can be driven in an afternoon, but deserves a full day or two.

Why drive Arthur’s Pass?

Because it shows you the whole width of the South Island in a single day. You start on the flat, golden Canterbury Plains, climb into a high, dry basin of tussock and limestone, cross the Main Divide among snow-capped peaks, and descend into the dense, green rainforest of the West Coast. The change in landscape, and in weather, from one side of the pass to the other is astonishing.

The road is also an engineering marvel. The original pass was a coach road built in the gold-rush era, and today’s route includes the Otira Viaduct, a curving bridge that carries the road across an unstable mountainside on the steep western side of the pass.

Castle Hill/Kura Tāwhiti

Castle Hill is a landscape of enormous grey limestone boulders scattered across the tussock hills, a place of spiritual significance to Ngāi Tahu and a favourite with climbers and photographers. A short walk from the car park leads among the boulders; it is an easy, magical place to stretch your legs.

Cave Stream

At Cave Stream Scenic Reserve, a stream flows through a 362 m limestone cave. Adventurous visitors walk through it, waist-deep in cold water, with headlamps; it is a genuine adventure and should only be attempted when water levels are low and with proper preparation. Everyone else can enjoy the walks above the cave entrance and exit.

Arthur’s Pass village

The village sits at around 740 m, surrounded by the peaks of Arthur’s Pass National Park. Visit the DOC visitor centre, then take the walk to Devils Punchbowl Falls, a 131 m waterfall reached in about an hour return. Arthur’s Pass is also one of the best places to see kea, the world’s only alpine parrot. They are intelligent and curious, and they will investigate your motorhome; admire them, but never feed them.

The Otira Viaduct

Just west of the summit, the road descends steeply into the Otira Gorge and crosses the Otira Viaduct. The lookout above the viaduct gives a superb view of the curving bridge and the gorge below.

Lake Brunner

A detour south from the highway leads to Lake Brunner and the small settlement of Moana, a peaceful lakeside spot known for trout fishing, with walks and camping.

What tours and experiences are available along this route?

• The TranzAlpine train. One of the world’s great train journeys runs between Christchurch and Greymouth over the same mountains, through tunnels and viaducts the road can’t reach. Some travellers ride it as a day trip from Christchurch before or after their campervan trip.
• Guided walks and climbs in Arthur’s Pass National Park.
• High-country station experiences, including farm stays, horse trekking and four-wheel-drive tours in the Craigieburn and Castle Hill areas.
• Skiing in winter at the club and commercial ski areas near Porters Pass and Craigieburn.
• Fishing on Lake Brunner and the high-country lakes.
• Glowworm walks and history at Greymouth, including Shantytown Heritage Park.

Where can you stay overnight on this route?

• DOC campsites in the high country around Lake Pearson and in Arthur’s Pass National Park offer simple camping in spectacular alpine settings.
• Arthur’s Pass village has accommodation and some parking for motorhomes.
• Lake Brunner has a lakeside holiday park and camping.
• Greymouth has holiday parks with full facilities.
• Freedom camping is limited inside the national park, even for self-contained vehicles; use DOC campsites, and see our freedom camping guide.

What are the driving conditions like?

The road is sealed throughout, but this is a true mountain road. From Christchurch, the climb over Porters Pass is steady with some steeper sections. The Arthur’s Pass summit is reached gently from the east, but the western descent through the Otira Gorge is one of the steepest stretches of State Highway in New Zealand, with sharp bends and grades that demand a low gear. Drivers heading east climb the same steep grades, so allow time and keep an eye on engine temperature.

Weather changes quickly in the mountains. Snow, ice, high winds and heavy rain can affect the pass, particularly in winter and spring, and the road is occasionally closed. Check road conditions before you set off, and see our winter campervanning guide. Some rental agreements have specific guidance for alpine passes; see our guide to roads to check in your rental terms.

Where are fuel, supermarkets and dump stations?

Stock up in Christchurch or on the outskirts before you leave; Springfield has a small store and fuel. Services are very limited between Springfield and the West Coast, with Arthur’s Pass village offering only basics. Greymouth has supermarkets, fuel and dump stations. See our dump stations and water guide.

Should you drive Arthur’s Pass east or west?

Either works. Driving west from Christchurch, you descend the steep Otira side, which most drivers find easier than climbing it in a heavy vehicle, and you arrive on the West Coast ready to head south to the glaciers. Driving east, you finish a West Coast loop by returning to Christchurch. Many South Island loops use Arthur’s Pass as the final leg back to Christchurch.

Can kea damage a parked RV at Arthur’s Pass?

They can. Kea are curious, strong-beaked parrots known for pulling at rubber window seals, wiper blades and anything left outside. Keep windows and doors closed, pack away outdoor gear, and never feed them, as human food harms them and encourages the behaviour.

Which routes connect to this leg?

• Before: start from Christchurch.
• Next, south: the West Coast glaciers from Hokitika, around 40 km south of Greymouth.
• Next, north: Buller and Paparoa in reverse, via Punakaiki and Westport to Nelson.

This leg features in our South Island 10-day loop and South Island in 14 days itineraries.
