Nestled among New Zealand’s Southern Alps is one of the most breathtaking experiences the country has to offer—the overnight hike to Mueller Hut in Aoraki/Mount Cook National Park. This awe-inspiring alpine trek boasts stunning 360-degree views of glaciers, ice cliffs, and New Zealand’s tallest peaks, making it a bucket list item for nature lovers and adventure seekers alike.
While Mount Cook may look and is tantalisingly close from the western side of the Southern Alps, particularly from Fox Glacier (just down the road from Ribbonwood Retreat in Franz Josef Glacier), the drive through Haast Pass to reach the eastern side is around 6.5 hours. But trust me, every second of the drive, especially in good weather, is worth it.
If you’ve been staying at Ribbonwood Retreat in Franz Josef Glacier or exploring the wonders of Glacier Country, this hike is the perfect complement to your trip over all New Zealand trip—offering a closer view of Aoraki (Mount Cook), New Zealand’s tallest mountain, from the eastern side.
The Journey to Aoraki/Mount Cook National Park
The drive to Mount Cook Village is part of the adventure. Once you round the stunning glacial blue waters of Lake Pukaki, the massive peaks of the Southern Alps dominate the skyline. The road to the national park dead-ends at White Horse Hill carpark, which serves as the starting point for not just the Mueller Hut hike, but also other popular trails like the Hooker Valley Track.
Be sure to stop at the Aoraki/Mount Cook Visitor Centre before your hike to collect hut tickets, get the latest weather updates, and sign your intentions in case of emergencies. Safety in remote alpine conditions is paramount, as the weather can change rapidly.
The Trail to Mueller Hut – A Challenge Worth Every Step
The hike to Mueller Hut is steep, gaining nearly 1,000 meters in elevation over 5.2 kilometers. Although the route is well-marked and accessible in summer conditions for experienced hikers, the gradient and terrain can be challenging, particularly above Sealy Tarns. Expect a combination of wooden steps, rock hopping, and scrambling over scree slopes on your way to one of New Zealand’s most iconic alpine huts.
Trailhead to Sealy Tarns (2 hours)
The first half of the hike consists mainly of steps—lots of steps. Known as the "stairway to heaven" by those who've braved it, this section involves climbing through a steep gut that rewards hikers with jaw-dropping views of the valley below. Sealy Tarns is the perfect spot to catch your breath and take in the reflections of Mount Sefton’s icefalls in the tranquil alpine tarns.
Sealy Tarns to Mueller Hut (2-3 hours)
Past Sealy Tarns, the marked path transitions into a rugged alpine route. Here you’ll traverse scree slopes and boulder fields, with the occasional pause to admire the avalanche sounds echoing across the valley. Reaching the ridge line delivers your first glimpse of the hut. From there, it’s about 30 minutes of boulder-hopping to Mueller Hut’s distinct red corrugated iron exterior.
Dropping Your Pack and Climbing Higher
Once at Mueller Hut, the reward of making it to 1,800 meters above sea level sinks in. After settling into the hut and taking a moment to rehydrate, head further up the rocky ridge behind the hut for even more spectacular views. This area, stripped of vegetation and dusted with snow, reveals a stark, almost otherworldly alpine plateau surrounded by towering peaks like Aoraki/Mount Cook and Mount Tasman, New Zealand's second-highest mountain.
This optional climb adds another elevation gain but delivers an unparalleled perspective—where you feel as though you’re standing at the edge of the world.
Overnight at Mueller Hut
The night at Mueller Hut is an experience in itself. Gaze at the star-studded southern sky, listen to the rumble of distant avalanches, and witness Aoraki glowing at sunrise. The 28-bunk hut is comfortable, with mattresses, gas cookers, and solar lighting. Do pack your own bedding, plenty of water, and food.
The hut brings together like-minded adventurers from across the globe, fostering a sense of camaraderie as you share stories, play card games, or simply marvel at the glaciers from the hut's deck.
The Descent
The following morning, after enjoying a hearty breakfast while soaking in the beauty of the mountains, prepare for the trek back down. Descents can put pressure on your knees, so take your time on the steep stair sections. Once you return to White Horse Hill carpark, you’ll feel a renewed appreciation for flat ground and the comforts of civilisation.
Planning Your Mueller Hut Hike
When To Go
The hike is most accessible in summer (November to April), as snow and ice add significant challenges during cooler months. Alpine experience is required if you plan to hike in winter conditions.
What To Bring
Pack plenty of water, layers for unpredictable weather, sunscreen, and sturdy hiking boots. Don’t forget snacks and high-energy foods like trail mix or chocolate.
Fitness Level
You don’t need to be an ultra-marathon runner, but this hike is particularly challenging due to its steep elevation gain. Some basic preparation, like walking stairs or hill training, can help.
Book Early
Bookings are essential for summer months. The hut itself fills up quickly, so reserve your spot as early as possible.
Explore Mount Cook, Then Return to Franz Josef
Though Aoraki/Mount Cook and Franz Josef Glacier stand just 40 kilometers apart as the crow flies, the dramatic Southern Alps make exploring both a longer but worthwhile adventure. The drive back to Ribbonwood Retreat through the Haast Pass is another stunning part of your trip, with opportunities to stop and enjoy lush rainforest walks, waterfalls, and lakes.
Back in Franz Josef, you’ll appreciate the cosy comfort of Ribbonwood Retreat, surrounded by its serene native bush and birdsong. Relax, reflect on your hike, and share stories with other travelers. If you gaze south toward Fox Glacier on a clear day, you can feel a sense of connection to Aoraki/Mount Cook—it’s right there across the divide, now a cherished memory from your incredible alpine adventure.
