Trek guide and park manager Katie Bryan caters for experienced riders as well as beginners like me, and quickly assures me that my horse, Emma, is "very quiet and happy to plod along".
Plodding is perfect - what better way to soak up the lush valleys and rolling hills of the King Country?
The views are spectacular and our hour-long trek reveals limestone rocks, babbling streams and miles of green fields dotted with cattle. We pause on top of a hill, take a deep breath of mountain air and watch fluffy clouds scudding across a blue sky.
I wouldn't go underground now if you paid me.
It's a far cry from Katie's last job as a restaurant manager in Hamilton. The 26-year-old, who grew up on a dairy farm in Cambridge, swapped city life to manage the gardens and wildlife park when her family took over the farm in 2009. She hasn't looked back since.
"It's a great place to live and I'm doing something I'm really passionate about," she says.
"A lot of our visitors are surprised at how much there is to do in Waitomo."
By the time we loop back to the paddocks, I'm ready to eat. Waitomo offers something for every taste and budget, from pub grub to pizza. Tonight, however, I'm treating myself to a spot of fine dining at the award-winning Huhu Cafe and Restaurant.
Owner and head chef Andy Rawles has developed a mouth-watering menu with a distinct New Zealand flavour. Ingredients are locally sourced wherever possible, wines are carefully matched to each course and the menu, which changes daily, features a handful of simple dishes cooked to perfection. I start with the sublime goat's cheese souffle served with warm honeyed pears and walnuts before moving on to the main event - slow-cooked duck with kumara mash, mandarin puree and deliciously crunchy garlic broccolini. I need a breather before dessert and, thanks to the relaxed atmosphere, I'm content to sit back with a glass of Marlborough pinot noir and admire the work of local artists adorning the walls. I eventually plump for the lemon tart with raspberry coulis and cream and I'm not disappointed.
After my dinner I waddle back to Altura Park and my bed for the night. Their new self-catering unit opened last year and sleeps up to four, with a queen-sized bed and two single bunks. It's an attractive mix of the rustic and contemporary with a heavy stable door opening into a bright and airy room, with pretty views overlooking the garden. The best thing by far is the peace and quiet, and I get a fantastic night's sleep.
And just to make sure every guest has an authentic farmyard experience, Chuck Chuck the rooster is in charge of your wake-up call.
