Return to the main entrance. There is a path straight ahead between two bushes. The park is on your left, the bastion of Miltiades to your right. Follow this path, and when you come across the first fork in the road, keep to the right and head towards Miltiades’ Bastion. The door is to your right and will bring you to a courtyard. We recommend you read the following stories here and then proceed through the second door to explore the actual bastion. The design is confusing, with lots of paths, doors, and ramps. As soon as you enter the bastion, you will come across a door to the right and a cobblestone staircase to the left. Go through the door. The first courtyard you will see is the prison of Kolokotronis. Further down, you will come across a series of courtyards with rooms worth exploring to get a sense of how claustrophobic life could be for the garrison and the prisoners. Return to the main door and go up the staircase to enjoy a bird's eye view of the courtyards and the view of the surrounding countryside. There's a bit of climbing involved and some steep and half-broken steps, so you need to be careful. But the higher you go, the better the view.
