Winter, when it arrives, can knock me sideways. This year, with the change in city, being farther north was a doozy. So for a dose of wellness and a mental escape from pervasive greyness, I sometimes like to visit Masaola Regenwald, a simulation of a Madagascar Rainforest at the Zürich zoo. This 11,000 m2 lush, oxygen-infused dome teems with life. Flora and fauna abound. Razor-edged ferns and soaring bamboo, trees and countless other species of plant provide a home to low swooping fruit bats and colourful birds to tiny geckos and multi-hued chameleons, tortoises and even tree-clambering lemurs. It’s more economic than a plane ticket, and yet still a transporting, mind-bending experience. The Treetop Walkway is particularly elevating, like a path to endless summer. And who doesn’t dream of that?
