If adrenaline sports, and bungee jumping in particular are your thing, but you think that some experiences are over in a flash and you want to find something that lasts a little longer, then why not go for a walk in the sky? This experience allows you to walk face down the side of a building, which will take you 5 mins to complete (or longer if you freeze). By the time you get to the bottom, your heart will be racing and the adrenaline will be pumping. Fun, fun, fun! To get there, head straight to Rondo Daszyńskiego Metro Station. To enjoy this experience, you must make an online reservation in advance. Open Apr-Sep, weekends only, but best check their site and Facebook page for the latest info.
