Mount John sits at just over a thousand metres above Lake Tekapo and carries the University of Canterbury's observatory, running since 1965 - a working research site with several telescopes, chosen for the Mackenzie Basin's combination of high altitude, dry air and very little cloud. In 2012 the surrounding area was declared the Aoraki Mackenzie International Dark Sky Reserve, at the time the largest gold-tier reserve in the world, achieved partly because the district had already restricted outdoor lighting from the 1980s to protect the observatory's work. Night tours run from Tekapo: transport up the mountain, telescope viewing and naked-eye guiding under skies where the Magellanic Clouds and the Milky Way's core are plainly visible. By day the summit road is open for a toll, with a cafe and a circular view over the lake and basin. Tours are cancelled for cloud, and the mountain is cold at night.
Background
The University of Canterbury Mount John Observatory, formerly Mt John University Observatory, is the leading astronomical research observatory in New Zealand. Set up in 1965, it stands at 1,029 metres on top of Mount John, at the north end of the Mackenzie Basin on the South Island, near the resort town of Lake Tekapo. Its telescopes include one of 0.4 metre, two of 0.6 metre, one of 1.0 metre and the 1.8 metre MOA telescope, opened in December 2004. In June 2008 it was announced that the observatory's new MOA-II telescope had found the smallest planet then known outside the Solar System. In June 2012 the 430,000 hectares around the site became the Aoraki Mackenzie International Dark Sky Reserve, one of only four such reserves at the time.

Highlights
- The research telescopes - a working observatory, not a display.
- The dark sky reserve - among the darkest accessible skies anywhere.
- The night tours - telescope viewing and guided naked-eye sky.
- The daytime summit - the road, cafe and view over the basin.
When to go
Winter gives the clearest and darkest skies but also the coldest nights. Book tours ahead and expect cancellation for cloud. New moon for the faintest objects.
Good to know
Tours are ticketed, booked out in season and cancelled for cloud - build a spare night into any plan. It is bitterly cold at the summit at night; the tours supply jackets. The summit road charges a toll by day.
Nearby
The Church of the Good Shepherd is on the lakefront below; Lake Pukaki is south-west.
