Today, around 4.4 billion people live in cities. That’s more than half the world’s population, set to increase to almost 70% by 2050. While urban environments bring with them myriad benefits, from economic advantages to entertainment, they also often come with a lack of connection to nature — and it shows. Travel destinations, hotels and wellness centres around the world are catching on, offering a variety of outdoor therapies that promise to help visitors with their physical and mental wellbeing.
