Lake Taupo is a lake situated in the North Island of New Zealand. It lies in the caldera of the Taupo Volcano. With a surface area of 616 square kilometres (238 sq mi), it is the largest lake by surface area in New Zealand, and the second largest freshwater lake by surface area in geopolitical Oceania, after Lake Murray (Extract Wikipedia)
The volcano is currently considered to be dormant rather than extinct because there has been moderate Fumarole activity and Hot springs along the shores of the lake.
We stopped for a coffee and bite to eat at the lake on our way from Napier to Hamilton.
