Start the tour in front of the Palace of Justice. Once you arrive, meet your tour guide, who is going to introduce you to the concept, give you all materials needed to complete the tasks in the first part and later share with you the fascinating stories behind the places you saw. You are free to experience the tour as you wish, walk in your own pace and stay as long as you want at the various stops. There are few things that might help you have the best possible experience – allow yourself the liberty to speak with locals and get lost – you never know what hidden treasures you might find. No matter what you do, make sure to come back to the final meeting point – Gifted Sofia, no later than 5 PM, to complete the final challenge. After that, your guide will lead you through your personal experience, and leave you with a full picture of the hidden side of Sofia.
