A flexible rainy afternoon in Funchal with a child

I have a free morning in Madeira and would like to spend it at one landscape viewpoint rather than moving between several stops for photographs. My starting point will be Funchal and I will not have a car, which makes the journey back as important as the view itself. I am happy to go after the early rush, and I would prefer a place where I can walk safely and wait if a cloud passes through. Some dramatic viewpoints appear easy on a map, but a steep final road or infrequent bus could make the outing much longer than expected. I would rather choose a modest view with reliable access, especially if conditions higher up are unsettled. For an initial shortlist I looked at 3 days in madeira without a car but I am checking individual routes instead of assuming every suggested stop works by bus. Is there one viewpoint you would suggest from Funchal? A short taxi ride for the last section is possible, although I would still want a clear way to return. I can keep the morning flexible around the forecast, and I would check current access information before setting off. I would appreciate a route that leaves enough time to get back comfortably.
