Not sure how you feel about heights, I’m pretty ok with heights. It helps if you can’t actually see the ground.
In this case, I got up really early (at least for a Saturday), arrived before everyone else and had all the time in the world to wait for the sunrise. Upside, when I crossed the bridge, it was still so dark that I couldn’t see the 100 meters of nothing beneath me.
If you’re ever around and considering going there, 7am is a good time to be there apparently. Also plan a 30-40 minute walk from the closest parking lot to the bridge. Cherry on top: access is for free.
