The Bund Sightseeing Tunnel is not an adventure for the light hearted. The trippy visuals and sound effects are rather bizarre and creepy. They look like something out of a nightmare or a psychedelic trip. Maybe the creators of this project did experiment with some illicit drugs to gain inspiration for this project. Moreover, it is more likely than not that some people tried going to this tourist attraction after “preparing” themselves beforehand. This trippy tunnel stretches from Pudong to Puxi in Shanghai, China, and is rated as one of the top five tourist attractions. We recommend visiting this place; just don’t take your kids along for the ride, since it might prove to be too scary for them.
