Pros & cons
PROS
- Huge Milford Sound and Tasman Sea sightlines from a relatively short route
- Fixed chains help on the steepest granite slabs when conditions are dry
CONS
- Route-finding gets sparse higher up; poor visibility can be serious
- Stream crossings can be hazardous or impassable after rain
- No facilities along the route or at the car park
Gertrude Saddle car park on the Milford Sound Highway (SH94). No facilities; nearest toilets are at the Divide or Homer Hut.
Expert-only alpine route. Slippery granite slabs, steep exposure, sparse markers higher up, hazardous stream crossings after rain, and avalanche risk in winter. Attempt only in dry, settled weather; turn back if conditions change.
What to expect
This is Fiordland’s high-drama day route: a short, steep push up the Gertrude Valley to a lofty saddle with sweeping views toward Milford Sound/Piopiotahi and the Tasman Sea. The approach starts mellow in a broad, glacial U-shaped valley with alpine vegetation and clear pools, then turns technical—think boulder fields, scree, and long, smooth granite slabs.
The slabs are the signature feature and the crux: you’ll use hands often, with fixed steel cables assisting on the steepest, most exposed sections near waterfalls. In dry conditions the scrambling is type‑2 fun; when damp or icy, it’s treacherous. The out-and-back is about 7–8 km total (roughly 4.3–5 miles), with 600–800 m of elevation gain, and typically takes 4–6 hours.
Difficulty and hazards
This is an expert-level alpine route, not a casual walk. Expect exposure, route-finding (markers thin out higher up), and several stream crossings that can become dangerous after rain. Smooth granite turns slick with any moisture, and the area carries avalanche risk in winter conditions. There are steep drop-offs—comfort with heights and scrambling is essential.
Scenery and geology
You’re traveling through a classic glacially carved valley—steep walls, hanging waterfalls, and sheer granite slabs everywhere. From the saddle, the payoff is huge: unobstructed views down-valley toward Milford Sound/Piopiotahi and out to the Tasman Sea on a clear day.
Best time to hike
Late spring through early autumn (December–April) in fine, dry weather only. Start early for stable conditions and ample daylight—Fiordland weather flips fast. Skip it if there’s any chance of rain, snow, or ice.
Logistics
Trailhead parking is at the Gertrude Saddle car park off the Milford Sound Highway (SH94). There are no facilities on the route, and sources note the nearest toilets are at the Divide or at Homer Hut near the trailhead. Cell coverage is unreliable. Bring everything you need: layers, rain gear, food, plenty of water, and a map/compass or GPS—and know how to use them. Leave your intentions with someone before you go.
Who will love it (and who won’t)
If you’re an experienced tramper comfortable with exposure, scrambling, and alpine decision-making, this is one of the most rewarding short days in Fiordland. If you’re new to scrambling, uneasy with heights, or it’s anything but bone-dry, choose another objective.
