Clean your soul of the sins in Seven Springs tunnel#17 of 21 things to do on Rhodes
But if you want to test your nerves then go through a long (almost 200 meters long) and narrow tunnel - only one person can walk through it at the same moment, and is immersed in absolute darkness. The only source of light is the sunroof. In the tunnel flow cold sources, which then fall into the pond, so you have to go through water that is ankle-deep.
It is believed that if you pass this tunnel, then you will become younger and receive forgiveness from the seven deadly sins.
