Great hike! Very well marked, and definitely not a boring hike! You get great views and close to Shannon falls, hike under the gondola at some points. There are short rock faces where there are ropes to assist. Quite steep but parts where it evens out.
We are relatively fit and it took us exactly 3hrs one way up. Best part is there is ice cream up at the top of the gondola! And an awesome view obviously :)
