Located 91 metres above sea level within the breathtaking Ku-ring-gai Chase National Park, Barrenjoey Lighthouse boasts unbroken views over (the ironically named) Broken Bay, the park and the Central Coast.
Thanks to its height, the site is one of the most popular whale watching spots in NSW, which you can reach via a leisurely one-kilometre hike.
If you're looking for a tougher trek, the short Smugglers Track will have you heavily breathing in the panoramic views when you reach the top.
The lighthouse is a sight to behold in itself and retains its original sandstone finish from the 1800s — and if you like that, check out these ten lighthouses near Sydney.
