Hey Jess I found a place called Patuna farm out in Martinborough that might be cool too, don't know if you've already checked it out - apparently its $35 for an hour, $55 for 2 hours... I know its a bit further away but just in case you were keen for something other than the tracks we go on out in Ohariu! here's the website if you want to check it out: http://www.truenz.co.nz/TourismWebsite06.php?id=1139
