Best Hiking Trails in Piopiotahi – Milford Sound

Piopiotahi – Milford Sound is often celebrated for its cruises and scenic flights, but it’s also a place where some of Aotearoa’s best hikes begin. From legendary Great Walks to short half-day adventures, the trails here lead you through ancient rainforest, across alpine passes and to lakes that feel untouched by time. If you’re ready to lace up your boots, these are the best hiking trails in Piopiotahi – Milford Sound.

Milford Track – The Finest Walk in the World

The Milford Track is a true icon, often called the finest walk in the world. This 54 km journey takes 4 days and climbs 1,773 m, leading you from Lake Te Anau across the dramatic Mackinnon Pass to finish at Sandfly Point on the edge of Piopiotahi – Milford Sound. Along the way you’ll discover lush rainforest, glacial valleys and the thundering Sutherland Falls.

• 🥾 Distance: 54 km point-to-point
• ⏱️ Duration: 4 days, 3 nights
• 🏕️ Bookings: Required with DOC huts in season

Camping isn’t allowed, so walkers stay in the three DOC huts — Clinton, Mintaro and Dumpling. Facilities include bunks, toilets and wardens during the Great Walks season (late October–April). Outside of this, huts are first-come, first-served and conditions are far more challenging.

Routeburn Track

The Routeburn Track is known as the ultimate alpine adventure. While the full track takes 2–3 days, the Fiordland side from Lake Mackenzie Hut to The Divide is a perfect one-day section. At 11.4 km with 332 m of elevation, it’s a moderate walk that passes alpine meadows and the spectacular 174 m Earland Falls.

• 🥾 Distance: 11.4 km point-to-point
• ⏱️ Duration: 3–4 hours
• 🏕️ Bookings: Required for huts and campsites in season

This track finishes at The Divide Shelter on the Milford Road, making it one of the most accessible ways to experience the magic of the Routeburn.

Key Summit Track

Starting at The Divide, the Key Summit Track is an 8 km out-and-back hike that’s perfect for a half-day adventure. It climbs gently through mossy rainforest to reveal panoramic views of the Humboldt and Darran Mountains, with a lookout toward Lake Marian.

• 🥾 Distance: 8 km out & back
• ⏱️ Duration: 3 hours return
• 🏕️ Bookings: Not required

Boardwalks across alpine wetlands add to the charm and the steady ascent makes this hike suitable for families. On a clear day, the summit views are nothing short of unforgettable.

Lake Marian Track

Tucked in a hanging valley above the Hollyford Road, the Lake Marian Track is short, steep and breathtaking. The 6 km return trail climbs 400 m through lush beech forest, across swing bridges and past waterfalls before arriving at a stunning alpine lake surrounded by jagged peaks.

• 🥾 Distance: 6 km return
• ⏱️ Duration: 3 hours return
• 🏕️ Bookings: Not required

The track is rough underfoot with tree roots and muddy sections that can be slippery when wet. Good boots are a must but the reward — mirror reflections of snow-capped peaks on calm days — makes every step worthwhile.

Kepler Track – A Fiordland Classic

The Kepler Track is a 58 km loop starting in Te Anau, designed to showcase Fiordland’s best scenery. Over 3–4 days you’ll pass lakeside beaches, climb into alpine ridgelines and take in jaw-dropping views across the national park. With 2,178 m of elevation gain, this Great Walk is challenging but unforgettable.

• 🥾 Distance: 58 km loop
• ⏱️ Duration: 3–4 days
• 🏕️ Bookings: Required in season

Most trampers walk anti-clockwise, staying in DOC huts or designated campsites. In the Great Walks season (late October–May), bookings are essential. Outside this, the track is only suitable for experienced trampers due to avalanche and weather risks.
