In my initial find_hikes search near Camacha, one of the community trails was "Camacha - Levada Dos Tornos" (4.1★, 36 reviews, 22.4 km, hard, out and back). This is likely the closest match.

Now, "Quatro Estrados" vs "Quatro Estradas" - the user wrote "Quatro Estrados" which seems like it could be a typo or variant of "Quatro Estradas" (Four Roads). The "Sítio das Quatro Estradas" is a specific locality in the Camacha area.

I also found from the Outdooractive result: "De Camacha até Sítio das Quatro Estradas" - a route from Camacha to Sítio das Quatro Estradas. So the hike the user is asking about seems to be an unofficial route that goes from Sítio das Quatro Estradas (a crossroads location) along the Levada dos Tornos towards Camacha. This is not an official PR trail managed by IFCN, but rather a community/unofficial route. Let me now find the video for this trail and prepare my answer. Actually, I should be more careful here.

Let me provide a good answer combining the information Ihave.The user is asking about the "Quatro Estrados - Camacha" hike in Madeira. Let me analyze what I've found: 1. The official trail network (IFCN) doesn't have a trail called "Quatro Estrados" or "Quatro Estradas" in our database. 2. From the web search, I found that: - "Sítio das Quatro Estradas" (also written as "4 Estradas" or "Quatro Estradas") is a location/crossroads in the Camacha area - There's a walk from "Sitio das Quatro Estradas" along the Levada dos Tornos to Camacha — this appears in the Rother Walking Guide as walk nr 15 - The Trailblazer guide describes "Walk 5: From Vale Paraíso to Camacha" starting at "Sítio das Quatro Estradas" — 5.2 km, 1:30 hrs - There's also PR 29 - Levada dos Tornos (Camacha) which is 13 km, partially open - The community trail on AllTrails: "Camacha - Levada Dos Tornos" — 22.4 km, hard, 4.1★ from 36 reviews 3. The "Quatro Estrados" spelling seems to be a variant of "Quatro Estradas" (Four Roads) — it's a location name (crossroads) near Camacha where several roads meet. 4. From the web results, this appears to be a walk along the Levada dos Tornos from Sítio das Quatro Estradas down to Camacha.

Let me look at the community trail data I already have: - "Camacha - Levada Dos Tornos" — 22.4 km, hard, 4.1★ from 36 reviews, not official IFCN PR trail And PR 29 also exists as a separate official trail. From the AllTrails community data near Camacha, I don't see an exact match for "Quatro Estrados - Camacha" but I have "Camacha - Levada Dos Tornos" which is related. Let me also check the Outdooractive result which mentions "De Camacha até Sítio das Quatro Estradas" — a 14.7 km route, T3 difficulty, 4:30h. The blog post describes a walk from Quatro Estradas along Levada dos Tornos to Camacha — it mentions steep sections, vertiginous parts where the levada is carved into steep cliffs, and it took about 5 hours (1120 to 1700). So: "Quatro Estrados - Camacha" is a walk along the **Levada dos Tornos** from **Sítio das Quatro Estradas** (a crossroads/intersection) to **Camacha**. It's NOT an official IFCN PR trail with that name — it's a common walking route using the levada path. PR 29 is officially called "Levada dos Tornos (Camacha)" and is a related official trail. The community trail I have is "Camacha - Levada Dos Tornos" from AllTrails (22.4 km, hard, 4.1★, 36 reviews). Let me provide a helpful answer combining what I know from the web search and the community trail data. I should note it's not an official IFCN PR trail named "Quatro Estrados" but rather a walk along the Levada dos Tornos starting from the Sítio das Quatro Estradas crossroads. Now let me also get the current status of PR 29 since the web search showed it as "Parcialmente aberto" (partially open). But I don't have PR 29 in our official database from find_hikes. Let me check once more with a different query. Actually, I already tried "PR 29 Levada dos Tornos Camacha" and got 0 results. And the broader search for "Quatro Estrados" also returned 0 official hikes. The madeirahiking.org site lists PR 29 as partially open, 13km. Let me compose the answer now.
