But there’s never been less of an excuse for holing up at the airport, especially this month with the opening of Bay South Gardens. This 134-acre green space has been five years in the making and comes with a cloud forest, heritage gardens, some artfully designed lakes and a World Expo-style collection of the planet’s plants. It centres around a group of cooled conservatories and a series of sky-scraping solar “supertrees” supplying the gardens’ rainwater and renewable energy. Opening on June 28, there will be two weekends of floral festivities, concerts, carnivals, an eco fair, garden hikes, movies under the stars and more.
