In Vroukounta (the northern part of Karpathos), a special and different festival takes place. You have to go to Diafani village and take a boat at around 10am or go on foot (hike) for about 2-3 hours, taking a path from Avlona. Ai Yiannis is a church in a cave, a unique place, that worth to see. When you reach there, leave somewhere a sleeping bag, because you will sleep there. After exploring the area (Vrykous was one of the four main ancient towns of the island) you can join the liturgy in the cave-church. Do not be surprised, because you will see women carrying at this place their traditional costumes. Later, free dinner is offered and music and dance will begin till early morning. The same thing happens the next day, but in fewer hours, because that day you will go back, again by boat or foot. Bring more supplies if you thing you may need, one big bottle of water, mosquito lotion and your camera. You can support economically the festive by leaving a few money as locals do.
