Excellent boiling mud!

Boiling mud pools are probably my most favorite feature of Rotorua (the smell of sulphur being probably the most distinctive feature of that locality). The other thing I like about Rotorua is, that like La Brea in Los Angeles, these geothermal events crop up everywhere. So in LA near the tar pits, tar oozes into parking garager, and in Rotorua you have sulphuric steam seeping out of sewer grates and even from cracks in the pavement.
