The rotting sulfuric mud has a nasty rotten egg smell its not very pleasant, but it sure is interesting. The green grey slimy water bubbles and burps, i don’t know how the ducks and geese live swimming on it. The whole region is known for its volcanic and geothermal activity. You see steam smoke and bubbles coming from the strangest places when driving around. The area has a lot of traditional Maori buildings and attractions, with some fairly scary carvings.
