This is definitely a touristy thing to do. It costs around $50 per person. I also wouldn't call it a trail. There is wooden pathways through the forest, some go up into the trees and others go along the forest floor. I didn't have an issue with crowds at I went on a Thursday morning. Grabbed a bus from Vancouver and it dropped us off couple minutes away. The bridge was pretty cool. It is a long suspension bridge. Having done it, I wouldn't feel the need to do it again, but if you can get there during a weekday, it's a pretty neat thing to see.
