Gertrude Saddle Route
An expert alpine route over river crossings, boulders and steep granite slabs to a dramatic saddle above Milford Sound.
Route overview
Gertrude Valley car park; valley route; stream crossing below waterfall; Black Lake area; cable-assisted slabs; saddle; return.
Gertrude Saddle is not a standard hiking trail. Above the valley, permanent markers disappear and experienced users must navigate through boulders and steep slabs, using fixed steel cables on the most serious section. Rain, frost, snow or ice can turn the granite into fatal terrain.
