4. Huge Black Garden Secret Island
https://www.youtube.com/watch?v=Q7OWafWZa9M Destiny is jam-packed with areas that players weren't supposed to find, but this is possibly the biggest one discovered yet. Just outside of the Black Garden level is a huge, floating rocky island, home to a strangely familiar cave. To find this secret area, you'll first need to go to the Black Garden. Next up, there's a series of tricky jumps that you'll need to carry out, which are explained fully in the video above. The island itself doesn't contain any enemies, but it does feature a cave that's identical to the one found in Tharsis Junction from the Mars map. There's not much to do once you do find this secret, but the challenge of using special jumps to get there is a lot of fun.
