Don't get me wrong, the place is beautiful. But we went to see the waterfall and there was none. Somehow travel guides forgot to mention that you can see it only during some months. So for sure no waterfall in September and October.

Fantastic narrow, twisty roads leading up through the pine forest, perfect for adventure bike riding😎 Very little water flowing down the falls, but what do you expect on a hot August day!

Beautiful geologically interesting spot where a waterfall formed due to the presence of harder layers. A small round trip is possible. Parking available near waterfall.

What a place, worth the visit, but a little scaring driving there. Go early in the morning

Loved the place it’s a very beautiful waterfall and you can take lots of amazing pictures

Very nice place to visit and have a look at these rock rich beaches. You can easily get there by about 15 minutes walking from Cascais city center. The area might get risky so make sure to stay inside the designated areas by the municipality.

It is a very beautiful spot. The waterfall was not running when I visited. However still pretty with very clear waters. There is a pretty fountain to get some fresh spring water.

Very nice. Because of the hot season there was hardly water flowing.

You can get there by car all the way to the water falls. I wish the road was one way (as it continue back to the starting point). The road is very narrow and go through a beautiful forest. We enjoyed both drove and visit. You can use the stairs and get closer to the fall. Plenty of parking about 30 meters before the falls. Near by table for a bring along meal.

Located in the Serra da Estrela mountain range in Portugal, Poço do Inferno literally translates to "Hell's Well." Found at an altitude of 3,500 feet (1,080 meters), the water gets so cold in the winters that it literally freezes over, like hell.

Park your car around 200 metres from this. Don't take your child to the lake, the access is not easy. Besides that there is not much to see

Beautiful place, well worth the visit. So fresh, nature in its raw state. There’s a “fountain” with running water that you can drink and it’s probably one of the best waters I’ve ever drank.

Zum Poco de Inferno kann man fast mit dem Auto hinauf fahren. Vom Parkplatz bis zum Wasserfall sind es nur ca. 100 Meter. Schöner danach Die Pg 1 Wanderung,⁹ geht kurz vor dem Poco de Inferno los und ist eine schöne kleine Wandertour von 1 1/2 - 1 3/4 Std dauer, feste Schuhe voausgesetzt, nicht für Schlappengeher geeignet. Bei uns im Spätherbst war leider schon wenig Wasser.

Der Ort ist schön gemacht, der Weg dahin ist ebenfalls schön. Im Sommer (August) sieht man allerdings keinen Wasserfall. Der Poco war fast vollständig ausgetrocknet.

Beautiful view! The walk itself is very challenging at the beginning and easy at the end. It takes more or less 2h.

Lovely little hike. Start is steep but the rest is pretty good. Loads of loose rocks at the beginning, but a very nice small hike.

I had the pleasure of visiting Poco do Inferno during my trip to Serra da Estrela and it was truly a magnificent experience. The waterfall descends a steep gorge of Ribeira de Lenadres and the sight of it was absolutely breathtaking, especially during spring. The lush evergreen forest that surrounds the falls adds to its natural beauty. To get there from Manteigas, you will have to drive about 4km along the main road towards Torre, and turn left just beyond Caldas de Manteigas to climb a further 6km to the falls. The journey itself is enjoyable, as you get to drive through picturesque landscapes. Upon reaching the falls, I was mesmerized by the sheer power and beauty of the water as it cascaded down the rocks. The natural flare bokeh created by the sun shining on the pine trees was a photographer's dream come true. The place is perfect for spending a couple of hours in nature, taking in the scenery and sounds of the waterfall. Overall, I would highly recommend visiting Poco do Inferno in Serra da Estrela. It's an amazing natural wonder that should not be missed

Very nice waterfall, forest and nature erea. The waterfall is reachable by car. Around few nice hiking trails, medium level and more.

Loved it .. water is so clean and fresh and lots of beautiful waterfalls and views .. stunning

A beautiful waterfall

Nice little waterfall. Actually, the walk around (1,5 hrs, starting from the parking) is more exciting than the waterfall

Small pedestrian route. Beautiful but a little technical. If you're coming you cannot miss this one!

Very beautiful and natural pleasure on the top of the mountain. All the trip is breathtaking.

The drive is quite hard and I bet I didn’t spend more than 15 minutes there, but it’s definitely beautiful and peaceful.

Probably better in the Autumn or Winter because it was pretty much almost dry now (Summer). Narrow access road but with a parking space when you arrive.
