299 steps to the top of this petrin tower but well worth the walk as the views across Prague are absolutely stunning. You could pay a bit extra to get the lift but where is the fun in that?! It cost us 150 czk each to enter the tower. It is well worth a visit and not just for the tower, Petrin Hill itself is lovely and there is a café underneath the tower. The tower offers a really great panoramic view over the whole area.
