You can download google cardboard app and use it for visiting a few landmarks, riding a great rollercoaster, etc. I use it mostly for watching movies. You rip your movies into MP4 format and download free version movie players. It makes you feel like you are watching the movie on a huge cinema size screen. Love it. There are apps for iOS that work as well. You can place MP4 movies via iTunes onto iPhones (Just be sure you own the film...otherwise it's illegal).
