I remember that on a previous visit I climbed to the top, felt the breeze, looked down, and discovered a cafe which I headed over to, so I went there hoping to see the changes on the island from above.
However, it seems that it has not been possible to climb to the top since 2016, and currently the area in front of the stairs is blocked off, which is a shame as it has deteriorated.
Its role as a tourist destination has now come to an end, so most people probably don't need to visit, but if you're interested, please do.
