There is a secret nature walkway that begins at the end of Udy St and loops around for about 4km. Ittakes you through pristine farmland, alongside the river and past historic cottages and lodges.
The cutest little shop on the planet exists in Greytown: Imperial Productions in McMaster St sells traditional style toy soldiers, hand-cast and hand-painted. They are collectors' items made to order for enthusiasts all over the world.
If you're old enough to remember New Zealand in the 1970s or before, you'll have some fondness for a time when shopkeepers came out to genuinely help you find what you were looking for, not try to sell you stuff you didn't need - and if you popped into a shop for a browse, you'd probably meet the owner at some point.
It was also a time when the day's pace was set by you and if you wanted to take your time over a cup of tea and a sandwich or a slice of ginger crunch, you could do that. You didn't pay for parking and you'd probably bump into someone you knew for an extended chat, as soon as you took a stroll down the street. That's the Greytown vibe that my wife Millie and I fell in love with in 2013 and the one we can't wait to come home to any time we travel away.
