Take some time out and watch the kids play on the awesome playground at Queen Elizabeth Park in Masterton.
Walk the swing bridge to visit the deer and feed the ducks on the lake. For a bit of light adventure, hire some pedal boats for a trip around the lake. There's also a great miniature train that goes for a spin each Sunday and miniature golf course for putting practise.
Expansive lawns here make for great picnic spots and if eating out's more for you, check out Cecille in the Park, a beautiful cafe in the middle of it all set in the historic Coronation Hall.
