The lighthouse has limited opening times but if you are on a cruise ship it is likely it will open when it ship is in port.
We chose walk around Akaroa rather than find our way to Christchurch and were not disappointed.
The lighthouse has been moved to this location and the story of its dismantling and restoration is an interesting read. The steps are tight to get to the top and the "balcony" around the top of the lighthouse is made of slats that you can see through. The view is terrific.
You make a donation to visit and you might be lucky enough to wind the mechanism. read more
