Madeira PR1 dangerous?

At the beginning of May I am planning to walk the PR1 trail on Madeira. I would like to know if this trail is risky or dangerous.

I am in good physical condition, but I have no experience with climbing.

It’s not a problem if the trail is long or physically challenging, but I don’t like extremely narrow paths with a big cliff. I don’t want to take a risk where a small mistake could have serious consequences. I don’t want to walk along very narrow paths where, if you misstep or twist your ankle, you could fall off the cliff.

I will definitely walk the “Stairway to Heaven,” but I am unsure whether I will continue with the full trail afterward, depending on the level of risk.

Does anyone have experience hiking this trail?
