At the craters of the moon there is lots of geofermal vents with information of each one. its set up with long stretches of board walk along with a entry with snack drinks and warm food before your walk. It would appeal to tourists that want to learn about the land and and geofermal activity in taupo.
I would rate it 7 out of ten beacuase i have done it many times but for a first time experince it would be a 8.
it could be imroved by adding railings for more saftey.
