Mount Cook National Park / Sealy Tarns
Not one for the faint-hearted or underprepared, Sealy Tarns Track offers unmatched views of New Zealand’s highest peak, Aoraki Mount Cook, as well as both Hooker and Mueller glaciers and their respective glacial lakes. It’s a tough one-day walk so consider staying at Mueller Hut and giving yourself a couple of days to really appreciate the tarns (small mountain pools) dotting the track.
