Siding Spring Observatory

Perched on the edge of the Warrumbungle National Park in New South Wales, Siding Spring Observatory is one of Australia’s most important astronomical research facilities. Home to the iconic 3.9-metre Anglo-Australian Telescope, this working observatory offers visitors a rare glimpse into the cosmos. The crisp, dark skies of the Warrumbungles make it an ideal spot for stargazing, and the on-site visitor centre provides engaging exhibits on space science and the history of the observatory. Whether you're an astronomy enthusiast or simply seeking a unique outback experience, Siding Spring delivers a memorable journey into the universe.

Highlights & What to See

• Anglo-Australian Telescope (AAT) – The centrepiece of the observatory; guided tours take you inside this massive telescope dome and explain its role in cutting-edge research.
• Visitor Centre & Exhibits – Interactive displays on the solar system, Aboriginal astronomy, and the technology used to study distant galaxies.
• Night Sky Viewing – The observatory occasionally hosts public stargazing events, where you can peer through smaller telescopes at planets, nebulae, and star clusters.
• Warrumbungle National Park – The surrounding park offers dramatic volcanic landscapes, walking trails, and Australia’s first Dark Sky Park designation, perfect for combining with your observatory visit.
• Virtual Telescope Experience – Even if you can't visit at night, the visitor centre features live feeds from telescopes around the world.

Suggested Time to Spend

Plan for at least half a day to fully experience Siding Spring Observatory. The drive from Coonabarabran takes about 30 minutes, and you'll want 2–3 hours to explore the visitor centre and join a guided tour of the AAT. If you're keen on night-sky programs, consider staying overnight in Coonabarabran or camping in Warrumbungle National Park. For a relaxed visit, combine a morning at the observatory with an afternoon hike in the national park.
