Lake Rotorua is the third largest lake in New Zealand, with an area of 80 square kilometers. It may be the crater left after the volcanic eruption, 26 meters deep. The geothermal activity below and around Lake Rotorua has continued. Geothermal steam continues to linger around the lake, and the sulfur content in the lake is high, thus forming a magical green-blue color. Strolling along the shore of the lake, you can see that the calm lake is surrounded by rolling hills and the curve is soft and connected to the sky. Everywhere you can see a large group of black swans swimming gracefully in the lake, and countless fat rainbow trout swims under the vast lake and becomes a tourist attraction. This is a lake with lots of wild ducks, many seabirds and many swans. Compared with the mountain lakes in the South Island, this lake is really inferior, but the seabirds are very enthusiastic, and a little bit of bread is all around. So I still have a good time.
