Lake Tekapo is home to one of the darkest skies in New Zealand. The lake itself is an otherworldly turquoise colour, surrounded by mountains, and at night when you climb Mount John to the observatory, the stars above you are unlike anything most people have ever seen. One of the most extraordinary nights of our entire time in New Zealand was spent stargazing at Lake Tekapo under the Southern Lights.

Lake Tekapo sits in the mackenzie Basin and the area is designated as an International Dark Sky Reserve — meaning light pollution is carefully controlled to protect the night sky. When you drive up Mount John in the evening and step out of the vehicle, you look up and immediately understand why this is so special.
The sky at Lake Tekapo is not like the sky anywhere else. The Milky Way runs across the entire sky — not a faint suggestion of it, but a proper river of stars so bright you can almost see by its light. The Southern Cross is unmistakeable. Satellites move silently across the darkness. Through the telescope at the observatory, you see detail in nebulae and galaxies that you never even knew existed.
The night we arrived at Lake Tekapo, the aurora forecast was surprisingly good. We went back out to Mount John late in the evening specifically to try and catch the Southern Lights. We stood on the mountain for what felt like hours, looking north (where the aurora appears in the Southern Hemisphere), watching, waiting, barely daring to move in case we missed it.
And then it started — a faint green glow appearing on the northern horizon, slowly intensifying and beginning to move across the sky. The Southern Lights at Lake Tekapo are real and they are extraordinary. Unlike the Northern Lights which apparently fill the entire sky with dancing green curtains, the Aurora Australis is more subtle — a shimmering, dancing glow that moves silently across the southern sky. It's quieter somehow, more intimate. Genuinely one of the most beautiful things we have ever seen.
A new moon is crucial — even a little moonlight makes the aurora harder to see.

It's genuinely freezing on Mount John at night — layers, a warm coat and a blanket are non-negotiable.
The aurora comes and goes. Expect to spend several hours on the mountain. Bring coffee and snacks.

Lake Tekapo is one of the most extraordinary stargazing experiences on earth.
