Let me try a broader search - maybe the trail is known by a slightly different name, or it might be in the community trails (non-IFCN). Let me search morebroadly.The user asked about the "Santo António da Serra - Levada Nova" walk. Looking at the results, there's no official IFCN PR trail with that exact name. However, in the community trails (community_trails), there's one that matches: "Levada do Moinho da Serra - Levada Nova - Ribeira da Santa Cruz" - This is a community route (unofficial, mapped on AllTrails) that includes the Levada Nova section near Santo António da Serra. Let me also check the official trails nearby - none of them directly match "Levada Nova" or "Santo António da Serra - Levada Nova." So the trail the user is asking about is a community/unofficial trail, not an official IFCN PR trail. I should present this clearly with the appropriate caveats. Let me also check if there's a YouTube video or curated video for this trail. Let me summarize the key info about this community trail: - Name: Levada do Moinho da Serra - Levada Nova - Ribeira da Santa Cruz - Rating: 4.1★ from 81 reviews on AllTrails - Difficulty: hard - Length: 12.1 km - Route type: loop - Location: 32.7016, -16.78666 - Description: Trail with a circular route that runs through a small section of Levada Moinho da Serra, Levada Nova and paths on the banks of Ribeira de Santa Cruz, all of them inserted in a territory surrounded by a fantastic landscape.
