The Irene flats can easily be ascended on grassy flats and in the gravel riverbed until the valley starts to narrow and climb at their southern end. From here progress is up the true left bank which is bouldery but generally open. The terrain opening up on the eastern valleyside lets you know where the creek dropping from Robin Saddle hits the Irene

Bottom of Irene flats to Robin forks: 2km, 1-2 hrs
