Sealy Tarns is a small flat area on the Mueller Ridge that is accessible from the Hooker Valley and Mount Cook Village. The track is extremely steep and features many switchbacks and steps built of large timber anchored into the ground. The area features a tarn (hence its name), an area suitable for tobogganing on the side of the ridge, and an excellent view of The Footstool, Aoraki/Mount Cook, both Hooker Glacier and Mueller Glacier and their respective glacial lakes, and Mount Cook Village.
