If you've gotten this far, it's most likely that you have the first thing you need, a mobile phone.
You'll need a QR code reader. If you do not have one on your phone, we recommend you download one immediately.
Once you have the means to pay the tole of €35, you're all set to go. You can pay by Paypal or credit card to start.
Now that you have the 3 tour tools, you'll need a designated leader to follow the instructions.
Have Fun!
