Hell's Gate, Rotorua

From www.hellsgate.co.nz:

“Brought to life by Rūaumoko, our land has inspired stories and excited visitors since the dawn of time. Around every turn you’ll experience something different – from cooking pools and steaming cliffs, to the largest hot waterfall in the Southern Hemisphere. Witness the mud volcano eruptions and land coral which grows day-by-day, and you’ll see first-hand why this place is called Hell’s Gate.

Once bathed in by Māori warriors, the mud and waters of Tikitere have soothed battle-scarred bodies for centuries.

Thanks to its beauty and healing properties Tikitere has been a destination for spa and nature seekers since 1871. In 1934 noted Irish playwright, George Bernard Shaw, visited and cited it as inspiration to change his once atheist beliefs. In awe of the boiling mud and steam billowing into the sky, Shaw is said to have exclaimed “this could be the very gates of hell.” Upon hearing this, local Māori decided the English name for the area would become Hell’s Gate.”
