Sealy Tarns is a small flat area with two small tarns halfway up the northern slopes of the Sealy Range. It is accessible from the Hooker Valley and Mount Cook Village via a tramping track maintained by the Department of Conservation (DOC). The track climbs steeply from about to via many switchbacks and over 2,200 steps built of large timber anchored into the ground. The track was established during the 1980s, and upgraded in 2012. The distance for a return trek from Hooker Valley Road to Sealy Tarns is 5.8 km (3.6 miles).
