At least a couple of days at the bike park – the shuttle bus is cheap. The native trails (Hatupatu, Tawhiti) off the top are great. The EWS has been through several times since I’ve ridden there so new trails have gone in and been ridden out since. Kung-Fu Walrus was a new one when I was last there 😀
I’m going to have to dig out the trail map to remind myself of what my favourites are.
Don’t forget to do Kutore (Kutties) on a wet day 😆
Rainbow mountain is short but fun. Do a couple of laps then stop of a hot dip in Kerosene Creek.
The trails off the gondola aren’t that great so never rode them.
The Jubilee Track is cheeky (walking track) and very contentious locally so don’t ride it.
We never did any helis from Rortorua so I don’t know what options that would open up.
Taupo trails (Craters of the Moon) were ok but I wouldn’t head there to ride them.
