Dark sky tourism is on the rise, reports the BBC. Light pollution causes astronomical bodies, such as stars, planets and the moon, to be less visible in urban areas. Many city-dwellers are seeking out dark places in order to better appreciate the night sky.
What's a good night sky? One in which you can see the milky way, according to Dan Hillier of the Royal Observatory, Edinburgh. The best nightscapes can be found on the International Dark-Sky Association's list of Dark Sky Places. These national parks, reserves and communities make an exceptional effort to preserve natural light; consider incorporating them into your next adventure.
