Levada do Caldeirão Verde (PR9) Madeira: The 'Jungle' Hike Through the Greenest Valley

I Didn't Expect Madeira to Feel Like This

The first thing you notice walking into the Levada do Caldeirão Verde is the noise. Not traffic, not people, but water. A constant, low roar of it rushing through the levada channel beside you, dripping from moss-covered cliffs above, and crashing somewhere far below in the Ribeiro Frio valley. I’d read the blogs calling it “jungle-like,” and I rolled my eyes. But standing there, with ferns brushing my shoulders and the air so thick with mist I could taste it, I had to admit: they were right. This is the trail that makes you feel like Madeira is a different planet.

I started from the Ribeiro Frio trailhead at 8:30 AM on a Tuesday in May. The parking lot, coordinates 32°43'57.6"N 16°53'06.3"W, held maybe 30 cars, and I grabbed the last spot. By 9 AM, the overflow was parking along the road. The trailhead has no facilities, so plan accordingly. I’d stopped at the Levada Walk Madeira tour earlier that week, and the guide had prepped me for the microclimate shift. Still, nothing prepares you for walking from sunshine into a tunnel of green so dense it feels like night.

The PR9 is 8.7km out-and-back, with a 450m elevation gain spread across the whole route. It’s not flat, anyone who tells you levada walks are flat hasn't done this one. You’ll climb stone steps, duck under rock overhangs, and cross narrow bridges over gullies. The path follows the levada channel, and in places it’s barely 60cm wide with a 10m drop on one side. No railings. If vertigo is an issue, skip this one and stick to Levada dos Balcões, it’s a 1.5km flat paved walk with guardrails and a view of the same mountains.

I met a levada keeper named Sr. António about 2km in. He was in his sixties, knee-deep in a channel, clearing silt with a metal rake while his dog slept on the path. I stopped to ask about the trail ahead, and he spent 20 minutes explaining how the 15th-century levada system actually works, that water rights are still allocated by the same “rodízio” (rotation) system the original settlers designed, where each farmer gets the flow for a set number of hours per week. He pointed to moss patterns on the channel walls to show where the water level should be. He didn't speak English. My Portuguese was terrible. But we communicated through gestures and the universal language of point-at-thing-and-nod. I think about Sr. António every time I walk a levada.

The Moments That Made Hiking in Madeira memorable

The PR9 has three distinct acts. Act one: the forest walk. You’re under a canopy of laurel and til trees, with the levada gurgling beside you. It’s cool, damp, and the light filters through in shafts. Act two: the tunnels. There are two on this trail, and they’re the real test. The first is about 150m long, pitch black, with an uneven floor and water pooling in places. I used my phone flashlight, but I wished I’d brought a headlamp, it frees both hands for the slippery sections. The second tunnel is shorter, maybe 80m, but the floor is slick with mud. Inside, the temperature drops at least 5°C. I met a couple who turned back at the first tunnel because they didn’t have a light. Don’t be them.

Act three: the payoff. After the second tunnel, the valley opens up and you’re walking alongside a sheer cliff face with waterfalls cascading down from above. The final 500m is a series of stone steps descending into a natural amphitheater. At the bottom, Caldeirão Verde itself, a 30m waterfall plunging into a green pool. The water is cold, clear, and deep enough to swim in. I waded in up to my waist and felt the spray on my face. The echo of the water against the rock walls is so loud you can’t hear yourself think. It’s the kind of place that makes you forget there’s a world outsid

I’ve done this trail four times now, and every time I see something different. Once, a fire salamander crossing the path. Another time, a group of chaffinches that followed me for 200m hoping for crumbs. The vegetation changes by season, in spring, the ferns are so green they almost glow. In autumn, the moss takes on a golden tint. But the tunnels are always dark, and the water is always cold.

For first-timers who want the full north coast experience without the logistics, I’d recommend the Madeira Northern Wonders Jeep Tour. It covers Porto Moniz lava pools, Fanal Forest, Seixal black sand beach, and the coastal road between São Vicente and Porto Moniz, all in one day. The open-top jeep means you feel every climate zone, so bring layers. It’s a solid backup if you don’t want to drive the hairpin roads yourself.

What Really Surprised Me About Madeira

The microclimates. I started PR1 on a cloudless morning in April, t-shirt weather at the Arieiro carpark, sunglasses on, feeling smug about my timing. By the time I reached the tunnel at the 2km mark, the temperature had dropped 12°C and I was walking through freezing fog so dense I couldn't see the next trail marker. The microclimate shift happens at the ridge between Arieiro and Ruivo, the north coast weather spills over like a lid coming off a pot. I finished the hike shivering in a thin rain jacket I'd almost left in the car. Now I carry a proper thermal layer on PR1 every single time, even when Funchal is 28°C.

Same thing happens on the PR9. The trail starts at 860m elevation in Ribeiro Frio, and as you descend into the valley, the humidity spikes. I’ve seen the temperature drop 8°C between the trailhead and the waterfall. The IPMA forecast said “partly cloudy” the day I last walked it. By the time I reached the first tunnel, it was drizzling. By the waterfall, it was pouring. The north coast gets about 2,000mm of rain per year, double what Funchal sees. If you’re hiking on the north side of the island, assume it will be wetter and colder than the forecast suggests.

Another surprise: the crowds. I arrived at the PR9 trailhead at 8:30 AM and had the first 2km mostly to myself. By 10 AM, I was passing groups of 15-20 people, and the waterfall was packed. I counted 32 people at the pool when I got there. The trick is to start before 9 AM, or go on a weekday in shoulder season. I did it once in November and saw only 4 other hikers the entire morning. The waterfall was all mine for 20 minutes.

And the tunnels. I can’t stress this enough: they are pitch black. No ambient light at all. I watched a woman try to navigate the first tunnel using her phone’s screen brightness, she tripped on an uneven stone and fell into the levada channel. She was fine, just wet and embarrassed, but it could have been worse. Bring a headlamp. I keep a Petzl e+Lite in my daypack at all times now. It weighs 26g and costs about €20 at Decathlon in Funchal. Worth every gram.

Sofia Almeida's Insider Tips for Getting It Right

I’ve made enough mistakes on Madeira’s trails to fill a small book. Here’s what I wish someone had told me before I started:

• Check IFCN trail status the morning of your hike. The IFCN hotline (291 211 800, English option 2) updates by 7:30 AM daily. In August 2025, 23% of levada trails had unplanned closures on any given day, maintenance, landslides, or fire risk. Check ifcosteiros.pt before you leave your accommodation. I’ve driven 45 minutes to a closed trail more than once.
• Parking fills fast. The PR9 trailhead at Ribeiro Frio holds about 30 cars. By 9 AM, it’s full. The overflow area is a 200m walk down the road, but there’s no marked lot. For the Rabaçal trails (PR6/PR6.1), the forestry house lot holds 80 cars and fills by 9 AM. Use the shuttle from the upper lot (ER110 roadside, ~120 spaces) instead, it rarely fills before 10 AM. The shuttle costs €2.50 one way, €4 round trip, cash only. Look for the yellow ‘Parque’ sign or you’ll miss it.
• Download offline maps before you leave Funchal. Madeira’s 150+ road tunnels kill GPS signal completely. Google Maps will spin helplessly between Funchal and Santana. Download Offline Maps in Google Maps or use Komoot/AllTrails offline before you leave your accommodation. On the PR9 itself, mobile coverage is zero past the trout hatchery for about 2km, then intermittent. I use offline maps every time.
• Rent the right car. A Fiat 500 or similar city car will struggle on Madeira’s mountain roads. The PR1 access road has 40+ hairpin turns with 20% gradients. I rented a manual 1.2L petrol with proper ground clearance and it was fine. Europcar and Guerin allow their standard fleet on mountain roads; Goldcar and Sixt explicitly forbid driving on ER101 and ER110 in their small print. Pickup in Funchal is cheaper than airport pickup by about €15/day.
• Buy cheap hiking poles at Decathlon in Funchal. Basic aluminum trekking poles: €12.99 (Quechua brand). Adjustable carbon poles: €24.99. The tourist shop at the PR1 Arieiro summit kiosk sells the same basic poles for €35. I bought mine at Decathlon in Madeira Shopping (floor 2) and they’ve lasted three seasons.
• Start levada walks before 9 AM. This applies to every popular trail, PR9, 25 Fontes, PR1, Balcões. The crowds arrive between 9:30 and 11 AM. If you start at 8 AM, you’ll have the trail to yourself for the first hour. By 10 AM, you’re sharing the waterfall with 30 people.
• The Rabaçal shuttle is cash only. There’s no card reader at the booth. Bring €5 notes or coins. I’ve seen people turned away because they only had a €20 note and the driver couldn’t make change.

What I Wish I'd Known Before I Went

I walked the PR9 for the first time in July, and I made every mistake in the book. Here’s the list:

• The tunnels are longer and darker than you expect. The first tunnel is about 150m, the second about 80m. Both are pitch black. I used my phone flashlight, but it wasn’t enough, I tripped on an uneven stone and twisted my ankle. Now I carry a proper headlamp. The tunnels also collect cold air; the temperature drops noticeably inside. If you’re prone to claustrophobia, you might want to skip the second tunnel, there’s a bypass path that goes over the top, but it’s steep and muddy.
• The trail is not flat. The PR9 gains 450m over 4.35km out. It’s a steady climb with stone steps, not a gentle stroll. I saw people in flip-flops and sandals at the trailhead. I saw them turning back 500m in. Wear proper hiking shoes with good grip, the levada channel makes the path wet and slippery. I wear Salomon Speedcross 5s and they’ve never let me down.
• The north coast weather is unpredictable. I checked the IPMA forecast before I left Funchal: “partly cloudy, 22°C.” By the time I reached the first tunnel, it was 14°C and drizzling. By the waterfall, it was 11°C and pouring. I was soaked and cold for the entire return hike. Now I always carry a waterproof jacket and a thermal layer in my daypack, even when the forecast looks perfect. The north coast gets about 2,000mm of rain per year, expect it to be wetter and colder than the forecast suggests.
• Parking is a nightmare after 9 AM. The Ribeiro Frio lot holds 30 cars. I arrived at 9:15 AM and had to park 400m down the road on a blind curve. When I came back, there was a note on my windshield from a local asking me not to park there because it blocks access for their tractor. I felt terrible. Now I start all levada walks before 8:30 AM. For the PR9, that means leaving Funchal by 7:30 AM at the latest.
• There are no facilities at the trailhead. No toilets, no café, no water refill station. The nearest public toilets are at the trout hatchery in Ribeiro Frio (200m from the trailhead), but they’re not always open. Plan accordingly. I always fill my water bottles at the Paul da Serra picnic area (ER110, near the Rabaçal turn-off), there’s a free public refill station there.
• Book sunrise transfers 3+ days in advance during peak season. I’ve had groups of 6 unable to find a single available slot for the entire week in August. The Viator operators running PR1 sunrise transfers only take 8-12 people per van, and they sell out consistently. If you want to do the Arieiro-to-Ruivo traverse with a transfer, book by Wednesday for a Sunday hike. Winter (Nov-Feb) you can usually book 24 hours ahead.
• Levada walks are not all the same difficulty. I made the mistake of thinking “levada” means flat. It doesn’t. The PR9 has serious elevation gain and exposed sections. If you’re a beginner, start with Levada dos Balcões (PR11), it’s 1.5km each way, flat, paved, with guardrails at the viewpoint. Then work up to the PR9. My guide to 25 Fontes vs Alecrim vs Risco breaks down the Rabaçal options in more detail.

Despite all that, the PR9 is my favorite levada walk on the island. It feels genuinely remote, like you’re walking through a prehistoric jungle. The tunnels add an adventure element that most levada walks lack. And the waterfall at the end is one of the most powerful I’ve seen in Madeira. If you’re fit, prepared, and willing to start early, it’s absolutely worth the effort. If you’re short on time or prefer a gentler introduction, start with the easy levadas in my beginners’ guide.
