Smelling, but very interesting!!
Rotorua and it's volcanic attractions are really cool. We started our stay with the Kuirau Park, a free park in the centre of the city. Next day we visited Waimangu Volcanic Valley. Beside seeing crazy volcanic activities you can have a nice walk/hike there.
Insider Tip:Rafting on the Kaituna River at Okere Falls. Great!! Down a 7 m waterfall.
