Welcome to Arizona on Instagram: "This hidden waterfall only appears during the rain or right after 😮 Who’s adding it to the list 🌧️ It is called Massacre Falls! This 5.8 mile trail is one of the most unique hikes in the Superstition Mountains. We highly recommend checking the weather before heading out. Good to know before you go: • Pack it in and pack it out, keep these natural spots pristine • About 1 hour from Phoenix to the trailhead • Around 3.5 hours hiking time • 5.8 mile out and back,
