Rotorua is built on a volcano, in fact a volcanic eruption in 1886 created the land we are on now, also killing over 150 people. The rolling hills and lakes that are surround Rotorua were created when this happened. Because of the many volcanoes around Rotorua and the lava beneath the Earth, there are many hot springs throughout the town. Here are some the hot springs that we explored near the Bay of Plenty and throughout the parks in the city.
