The trail "Madalena do Mar – Sítio do Pinheiro – Achada da Santo Antão" doesn't appear in Madeira's official PR (Percurso Recomendado) network managed by IFCN, so I can't confirm its current open/closed status, official distance, or give it an official difficulty rating. It's also not in the broader AllTrails community catalogue under that exact name.

However, the area you're asking about — Sítio do Pinheiro, above Madalena do Mar and Arco da Calheta on the southwest coast — is covered by a community-mapped trail that passes through some of the same waypoints:

Community route (mapped on AllTrails) — not part of Madeira's official PR trail network managed by IFCN (the regional government's forests & nature-conservation authority), so it has no official open/closed status and no maintenance/signage guarantee. Check access and conditions locally before going.

Since you're interested in Madalena do Mar, there are several community-mapped walks starting right from the village — all easier and shorter:

All of these are community routes, not official IFCN PR trails — they carry no official open/closed status.

The route Madalena do Mar → Sítio do Pinheiro → Achada da Santo Antão may be a local/older name for a path that connects into the Levada Nova network above Arco da Calheta. If you've seen it mentioned in a guidebook or on a walking map, the Sítio do Pinheiro section likely overlaps with the community trail above. However, since it's not an official PR trail, I can't verify its current condition or whether the full route to Achada da Santo Antão is still waymarked or passable — I'd recommend checking with local tourist information in Ponta do Sol / Madalena do Mar before setting out.
