Incredible views from the bridge (if you can handle looking around without getting vertigo!). The…read morebridge wasn't busy when I first crossed it so it didn't move too much. The way back was a little more nerve-racking as there were more people and I was trying to walk fast.
There's a nice little area on the far side, where you can sit and admire the castle ruins, before returning back across the bridge. I couldn't see an alternative way back so make sure you can stomach crossing the bridge twice!
BEWARE; The lift pass costs extra (so your highline ticket goes from €10 to €19 very quickly!). I didn't read anything about having to take the lift up on the website, so if the information is on there, it's not obvious. I couldn't see if there was a way to walk up but I assume there is...? However, the lift does take you up to the ruins and you can walk around them for free.
You can also get an additional lift pass (for another fee) to continue to the very top way above the castle ruins. I didn't feel the need as the view is already pretty spectacular from the castle ruins.
Worth a visit if heights are your thing!
