Frying Pan Lake is a geothermal feature located in Waimangu Volcanic Valley on the North Island of New Zealand. It is the largest hot spring in the world by volume and is known for its vibrant turquoise waters and bubbling mud pools.

The lake is approximately 38 meters deep and measures about 200 meters in length and 40 meters in width. It is surrounded by hot springs and geysers, with temperatures that can reach up to 50-60 degrees Celsius. The geothermal activity in the area is caused by the Rotorua caldera, which is a massive volcanic crater that last erupted around 240,000 years ago.

Frying Pan Lake gets its name from its circular shape, which resembles a frying pan. The lake's unique color is due to its high silica content, which reflects the sunlight and creates a brilliant blue-green hue. The lake is also home to unique microbial communities that thrive in the extreme conditions of the geothermal environment.

The Waimangu Volcanic Valley, where Frying Pan Lake is located, is part of the Taupo Volcanic Zone and is a popular tourist destination in New Zealand. Visitors can explore the valley and observe the geothermal activity, as well as take guided tours to learn more about the geology and history of the area.
