Expect sudden weather changes in Wellington, so bring swimsuits, towels, jackets or jumpers, hats, long pants and shorts. Water and a picnic mat are always a good idea. We always take a picnic everywhere in Wellington, as it's perfect for it. Plus, dining out is pricey.
Be aware that the playground has water and lots of games for kids. The beach is near the playground, so don't forget swimsuits, hats, water and sun protection.
This is a place to spend the whole day, but the best day is Sunday, as they have the Kapiti Miniature Train going on. A definite favorite with the nuggets.
Again, a picnic is a great idea. The day is long and they always want to to eat and drink.
