Gertrude Saddle
Gertrude Valley, Black Lake, and the saddle view over the Darran Mountains toward Milford Sound
The route
The line through Fiordland NP (Milford Road), New Zealand - waypoints, elevation and the day-by-day shape of the walk.
Season & conditions
Dec-Mar, dry settled weather only
Slabs lethal when wet/icy; sudden Fiordland rain; there have been multiple fatalities here
Black Lake reflections; hanging-valley views to Milford Sound from the saddle
Attempt only when dry and snow/ice-free (roughly Dec-Mar); deadly when wet or frosty. Confirm.
On the trail
Boulder-strewn valley, tarn, then steep glaciated rock slabs with cables
Steep polished rock slabs with steel cables; real fall exposure near the saddle; scrambling
Route-marked with cairns only - navigation and route-finding required; easy to stray onto dangerous ground
Confident, sure-footed hikers with scrambling comfort only; not for beginners, children or the exposure-averse
Kea (will investigate packs), rock wren
Alpine herbfield, tussock
Moderately popular in fine weather but never crowded; feels remote
Turn around at Black Lake (below the slabs) for a safer, still-scenic option
Getting there & staying
Gertrude Valley car park on the Milford Rd near the Homer Tunnel, ~1.5 h from Te Anau
Drive or Milford Rd bus; no shuttle needed
None
Grippy footwear, layers, water; no coverage; PLB advised; some carry a helmet/harness for the cables
None; nearest at Te Anau/Milford
Not required, but guiding is sensible for the inexperienced
Permits & safety
None (free public conservation land)
Permits and operators change - confirm before booking.
Wet/icy slabs and off-route falls are the killers here - do not go in poor weather; strong turnaround discipline
Retreat the way you came; no coverage - carry a PLB; helicopter evac
