Oh my goodness! This was so my experience! I April 2018 - probably a 90 minute wait for the cable car to go back down. My husband is not a “Wait in line” kinda guy so we thought well…”Why not take the steps”? I had on cheap Greek style sandals I bought in the US with a very slick bottom but didn’t think much of it. I was 53 and in relatively good shape and hubby was in great shape at 58. I nearly died a million time s walking down. It took us almost 3 hours and you are at a constant angle trying to keep yourself from falling forward. It’s very steep and your thighs are shaking like jello when you get to the bottom. It’s not just walking down steps….there are wide ledges between each step so you walk 5-6 steps (always on an incline) and the go down a wide step on a sharp hairpin curve then do it again. Interspersed on these wide steps and inclines are dried donkey poo with straw strewn about. It makes it extremely slippery and then when you factor in the fresh donkey poo…well there is that to consider. I slipped and slid so much while having a death grip on the rail and my husband…I finally took off my cheap sandals and just walked bare foot in the dried donkey poo to keep from breaking my neck. I could have didn’t one of the donkeys down but they looked more miserable and less sure footed than I was so I decided not to torture a poor animal by asking it to carry me down the side of a sheer island. Going to Santorini again in April 2023 - will wait for the cable car this time!
