Sealy Tarns Viewpoint is the end point of the Sealy Tarns Track in Aoraki/Mount Cook National Park, Canterbury. The track is known as the "stairway to heaven", with 2,200 steps climbing 600 metres to freshwater tarns. The views take in the Hooker Valley and the peaks of the area, including Aoraki/Mount Cook on a good day, and there are alpine flowers in summer. The walk starts on the Kea Point Track, from the Aoraki/Mount Cook National Park Visitor Centre or from White Horse Hill car park at the end of Hooker Valley Road.
The track is very steep and narrows near the tarns, and it is easy to slip when snow is present. There is no shelter or alternative route, and bad weather often comes in from the north-west. In winter the track can be extremely icy, and ice axes or crampons may be needed, with avalanche risk. The visitor centre gives advice on conditions. No dogs are allowed. Parking at White Horse Hill costs $2.50 per half hour or $25 a day as at 2026, and is free if you leave within 20 minutes. Payment machines take debit and credit cards only, and drones need a permit.
