Stirling Falls is a spectacular 151-metre (495-foot) waterfall located in Milford Sound, Fiordland National Park, New Zealand. Fed by rainfall and snowmelt, it cascades directly into the fiord from hanging valleys above. The falls are a prominent feature visible during boat cruises and are named after Captain J.G. Stirling.

Explore Milford Sound walks to discover other spectacular trails and viewpoints in this remarkable fiord.
While Milford Sound has several waterfalls, Stirling Falls stands out because of its consistent flow and the way cruise boats can approach it safely. Unlike Bowen Falls, which you can hike to on land, Stirling Falls exists in that magical category of wilderness that’s only accessible from the water. There’s no walking track, no viewing platform, no cafĂ© nearbyâjust raw nature doing its thing.
The falls drop from a hanging valley, which is geology-speak for a valley that got left high and dry when glaciers carved the main fiord deeper during the ice ages. These hanging valleys are everywhere in Fiordland, but Stirling’s particular setup creates this perfect vertical plunge that never touches rock on the way down. In full flow after heavy rain, the water column becomes so thick with volume that you can barely see through the spray.
Here’s what the brochures don’t tell you: not all cruise operators approach Stirling Falls the same way. Some boats get close enough that you’ll need to stash your phone in a waterproof bag (and yes, you absolutely need one). Others maintain a more respectful distance for those who’d prefer to stay dry while getting photos.
The smaller vesselsâkayaks and small tour boatsâcan get closest, though kayakers need to be cautious of the turbulent water near the base. I’ve watched kayakers get absolutely drenched paddling underneath, which looks exhilarating but also slightly terrifying. The downdraft created by the falling water can push boats around, so captains approach at an angle rather than head-on.
If you want the full sensory experience, position yourself on the bow of the boat rather than inside the cabin. Bring a towel. Seriously, bring a towel. Your waterproof jacket will help but won’t save you from a proper soaking. Some people treat it like a ride at a theme park and deliberately stand where they’ll get drenched. Others hide behind the cabin and still end up wet.
The lighting at Stirling Falls can be tricky. The fiord walls create deep shadows, especially in the middle of the day when the sun is overhead. Early morning or late afternoon cruises often provide better light, though honestly, the falls photograph well in almost any conditions because of the dramatic contrast.
Use a fast shutter speed if you want to freeze the water droplets, or slow it down to 1/30th of a second or slower for that silky smooth effect. The boat will be moving though, so you’ll need steady hands or accept a bit of artistic blur. Polarizing filters help cut through the mist and enhance the dark water.

Wide-angle lenses capture the scale better, but don’t discount a telephoto for detail shots of the water crashing into the fiord. The impact zone creates fascinating patterns and sometimes you’ll catch rainbows in the spray on sunny days.
Protect your gear. Even if you’re not getting directly sprayed, the mist permeates everything. A simple plastic bag or rain cover will save you from a ruined camera. Lens cloths are essentialâyou’ll be wiping spray off your lens constantly.
Stirling Falls changes personality with the seasons and weather. After heavy rainfall (which is often in Fiordlandâit’s one of the wettest places on Earth), the falls can swell to an absolutely thunderous torrent. The usual elegant ribbon transforms into a raging white column that you can hear from hundreds of metres away.
During drier periods in summer, the flow reduces but never disappears entirely. Even in the “dry” season, Milford Sound receives substantial rainfall, so you’ll rarely see Stirling Falls as anything less than impressive. Winter brings snow to the peaks above, which feeds the falls as temperatures rise during the day. The surrounding cliffs sometimes have additional temporary waterfalls creating a spectacular cascading effect.
The water colour changes too. After heavy rain, it can carry glacial silt and appear milky grey. In calmer conditions, it runs clearer and you can see the dark tannin-stained water of the fiord more clearly.
| Waterfall | Height | Access | Flow Consistency | Best Feature |
|---|---|---|---|---|
| Stirling Falls | 151m | Boat only | Permanent | Close boat approach |
| Bowen Falls | 162m | Walking track + boat | Permanent | Can hike to base |
| Lady Bowen Falls | 162m | Boat only | Permanent | Twin falls effect |
| Fairy Falls | Various | Boat only | Temporary | Appears after rain |
Something most visitors don’t realize: there’s an entire valley system above Stirling Falls that you can’t see from the water. The falls emerge from a narrow cleft in the cliff face, but behind that opening is a hanging valley with its own ecosystem. Adventurous climbers and Department of Conservation workers who’ve accessed the area report finding pristine alpine tarns, ancient forests and some of New Zealand’s rarest plants thriving in complete isolation.
The MÄori name for this area references the spiritual significance of these hidden valleys. Traditional stories speak of these places as being guarded by taniwha (guardian spirits), which makes sense when you consider how inaccessible and mysterious they are. Even with modern technology, much of the terrain above Stirling Falls remains unmapped in detail.
Milford Sound averages over 6 metres of rainfall annually, so there’s a very good chance you’ll experience some precipitation during your visit. This isn’t necessarily badâin fact, the fiord is arguably more spectacular in the rain when dozens of temporary waterfalls appear on the cliff faces and Stirling Falls swells to maximum flow.

For those with paddling experience, kayaking in Milford Sound offers an entirely different perspective on Stirling Falls. Several operators offer guided kayak tours, and while you won’t paddle directly under the falls (that would be genuinely dangerous due to the turbulent water), you can get surprisingly close.
The sensation of approaching in a kayak is completely different from a cruise boat. You’re much lower to the water, more vulnerable, more connected to the environment. The sound builds gradually as you paddle closer. The spray hits your face. You feel the power through the paddle as the water churns.
Kayak tours typically take 2-3 hours and require moderate fitness. You don’t need previous kayaking experience for guided tours, but you should be comfortable on the water and able to swim. The guides know the safe approach distances and understand the water patterns around each waterfall.
While you’re in the area, several other remarkable waterfalls deserve attention. Hidden Falls offers a short walk from the Milford Sound Lodge with beautiful forest scenery. The Chasm provides a fascinating look at water erosion on the road to Milford. Humboldt Falls is visible from the road and runs year-round. For something more adventurous, the Grave Talbot Track offers backcountry exploration with waterfall views.
The cruise boat commentary usually points out Stirling Falls well before you reach it, giving you time to prepare. Use this heads-up to position yourself, secure loose items and get your camera ready. Some people miss the best viewing angle because they’re still fussing with gear when the boat approaches.
If you’re prone to seasickness, take medication before the cruise. The boats are stable, but they do rock when holding position near the falls, and the last thing you want is to be feeling ill during the highlight of your trip.
Most cruises include a stop or slow approach at Stirling Falls as standard, but it’s worth confirming when booking. Some express cruises may not approach as closely or linger as long.
The observation deck at Milford Sound itself offers a distant view of Stirling Falls on the opposite side of the fiord, though it’s far less impressive than the boat experience. This can be useful for scouting conditions before your cruise thoughâif you can see significant flow from that distance, you know you’re in for a spectacular close-up experience.
Bring a GoPro or action camera if you have one. These are perfect for the close approach when regular cameras need protecting. Mount it on your chest or head and capture the full experience hands-free.
Swimming isn’t permitted or practical. The water is extremely cold (8-12°C year-round), the current is dangerous, and the force of the falling water creates hazardous turbulence. Commercial operators maintain safe distances for good reason.
At 151 metres, Stirling Falls is impressive but not the tallest in New Zealandâthat honour goes to Browne Falls at 619 metres, also in Fiordland. What makes Stirling special is its accessibility and the way boats can approach closely, offering an intimate experience with a powerful waterfall.
No. Milford Sound’s maritime climate keeps temperatures above freezing even in winter. Snow falls on the peaks above, but the falls themselves maintain liquid flow year-round.
Most major operators approach to within 10-20 metres, but this varies by boat size, captain preference and conditions on the day. Smaller vessels can typically get closer than large cruise ships. Ask about approach distance when booking if this matters to you.
Morning cruises often have calmer conditions and better light, but the falls are impressive at any time. Afternoon light can create beautiful rainbows in the spray. After rain is when the flow is most spectacular, regardless of time of day.
No, it’s too far away. The falls are located several kilometres into the fiord from the terminal area. You’ll only hear them when your boat approaches closely.
Sand flies are a Fiordland pest, but they’re primarily an issue on shore, not on the water. Once you’re on the boat, they’re not a problem. Apply repellent before boarding though, as they’re notorious at the terminal area.
Milford Sound cruises operate in most weather conditions, including rain. Only severe weather like dangerous winds or flooding typically causes cancellations. If your cruise is cancelled, operators usually offer refunds or rebooking options.
I still remember the first time I actually *felt* Stirling Falls before I even saw it properly. We were on one of those smaller cruise boats in Milford Sound, and the captain announced we’d be getting close to the falls. Everyone rushed to one side of the boat with their cameras ready.
What struck me wasn’t just the heightâthough 151 meters is absolutely massive when you’re right thereâbut the sheer force of it. The boat inched closer and closer, and suddenly we were being hit by this fine, cold mist that soaked through my jacket in seconds. People were laughing and screaming a bit, that nervous excited kind of sound you make when nature reminds you how small you are.
The roar was deafening up close. I’d been taking photos, but I just put my phone away because it felt pointless. The water crashes down with such power that it creates its own wind, and I remember my hair whipping around my face, tasting that fresh glacial water on my lips.
When the boat finally pulled back and I could wipe my glasses, I looked around and everyone had this same dazed, grinning expression. We were all completely drenched, but nobody seemed to mind. There’s something about standing that close to a waterfall of that sizeâit’s humbling in a way that’s hard to explain to someone who wasn’t there.
