I have no idea where this is, except that it is VERY HIGH above the ground. Unless you are a mountain climber, you will have to take one of those very narrow bridges. Even those access points are not easy and will require you to be very, very careful about where you step.
Humm, reminds me of something Jesus said...
Matthew, Chapter 7 (WEB)
13 “Enter in by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and many are those who enter in by it. 14 How narrow is the gate, and restricted is the way that leads to life! Few are those who find it.
Being a genuine disciple of Jesus is NOT easy, you have to be careful about what you say, what you do- even what you think. Frankly, not everyone can do it. But, I think its worth it; and so, until my dying day- I will keep trying. I hope you will as well!!!
