Bridge To Another World

I found the trail to get to this bridge by accident. It's just to the side of one of the main trails. I almost went past it myself, but I was oddly attracted to it. I've watched as every other person walked right on by. The trail looks insignificant, but just around a corner I found the bridge. This is such a solitary place. I can be here and feel completely safe and free from any others. When you cross the bridge, you move into another world altogether. The trail there is small and dark. This is the trail that leads to the hidden river I've shown here before. If you find this bridge you're lucky. If you find the hidden river you're an everyday adventurer. I won't tell you where it is. See if you can find it.
