Aoraki Mackenzie International Dark Sky Reserve was established in 2012, and at 4300 square kilometres, it is the largest such reserve in the world. The most vital factor for a dark sky reserve is lack of light pollution, so it has to be in a remote location. The reserve includes Aoraki Mt Cook National Park, and the towns of Lake Tekapo, Twizel and Mt Cook. The best way to get there is in the comfort of a rental car, as there are no scheduled air or rail links to these locations.
There are tons of activities and attractions to indulge in the area. Try 4WD and kayaking tours, skiing, horse trekking, flightseeing, alpine guides, planetarium theatres and stargazing tours with observatories and high powered telescopes. All of which sounds fabulous and great, but at a cost which isn't exactly cheap as chips. But there are these fantastic cheap options...
Try these walks for a personal stargazing experience: Pines Beach walk- From Cowans Hill lookout car park to the Church of the Good Shepherd, is an easy walk through partly forest terrain, across Lilybank Rd to the lake shore where you can choose from these 2 options to base your star gazing destination… left to the Church of the Good Shepherd or right to Pines Beach. You will notice, driving around at night, that there is limited artificial light in the township of Lake Tekapo, and you'll need to slow right down to read the street signs. This is all part of keeping light pollution down for the dark sky reserve.
1hr 15min drive in your car rental from Tekapo, follow SH8 and turn off on SH80 on Mt Cook Rd to trace the shore of Lake Pukaki and choose any location along this road to park your rental car and view the spectacular sights of the stars in light pollution free skies. [Note: the closer you are to the village the narrower your views will become because of the mountains]
Freedom Camping: check out the Lake Pukaki site (The Pines) on Hayman Rd. Although there are no facilities available, it's free and you will be treated with breathtaking sunrise and sunset views.
When should you go?
Obviously the stars are there all year around, but in the winter months, you also have the chance to see the Aurora Australis, or Southern Lights. You need a clear night, with strong activity of solar winds, when the moon is at its darkest. Aurora Australis is hard to predict, so it is more about being in the right place at the right time.
But wait there's more: Geraldine Observatory
If all this naked eye viewing has whet your appetite for the high tech , there is an incredible affordable option. The Geraldine Observatory is a state of the art, private,roll on- roll off roofed observatory, run by Peter and Wyn Aldous. Peter has 40 years experience as an amateur astronomer, and offers tours on a donation basis. Yes, that's what I said, a donation. All proceeds go to South Canterbury Outreach Astronomy, which is all about making astronomy accessible to the public. You can arrange a session with Peter through his website, www.geraldineobservatory.co.nz
. Geraldine is a cute town, with a great supermarket stocking a surprising array of craft beers, roughly halfway between Christchurch and Lake Tekapo.
