A quieter Madeira itinerary

[JackSi]

I am looking for a first levada walk in Madeira, but route length alone does not tell me whether it will be comfortable. I am fine with a steady half-day hike, yet narrow paths beside steep drops are a different matter for me. Several routes seem to include tunnels, and I am not sure how much light or headroom to expect. I have looked through best levada walks in madeira but I would rather choose by conditions than by a ranking. After a wet evening, I assume a route can feel quite different from its photos. How do you verify a trail is suitable on the day and decide whether to postpone instead of pressing on? The return journey is also part of the decision, because I will not have a car and would prefer not to rely on an uncertain pickup. I would appreciate a beginner-friendly route idea, plus any warning signs that would make you choose a different day or trail. Even a familiar trail could be unsuitable in poor weather.
