The Pouhon Pia is a natural mineral spring in Spa, located in a wooded area about 150 meters northwest of the Chemin des Fontaines, which connects the source of the Géronstère with those of Sauvenière and Groesbeek. The spring is situated on a small stream, the Ruisseau des Pendus, near the Fagne de Malchamps at an altitude of approximately 435 meters. At the site of the spring stands a small stone fountain from the Géronstère source, installed after a fire in 1893. This fountain building is semi-cylindrical in shape, and there is a nearby shelter.

One of the many springs around Spa. The Pia spring, located at an altitude of 400 meters next to the Rau du Pendu, primarily contains the iron-rich water from the Malchamps fen.

Picturesque Chefna valley. One of those beautiful streams here, originating on the plateau of the Parc Naturel des Sources. The steep drop and rocky bottom make it unique. The water cascades over the boulders in waterfalls and pools. It flows gently now (July), but it will be raging in the rainy season.

The Barisart source (French: Source de Barisart) is a source in the Belgian municipality of Spa. The source is located south of Spa in the forest on the road Rue de Barisart. The water of the source comes from the Veen van Malchamps. The water of the Barisart source is extracted in a field higher up (50° 28′ 26″ N, 5° 51′ 56″ E) by Spa Monopole and is sold under the name "Spa Barisart". The water of the Barisart source is carbonated and is of a similar type to that of the Marie-Henriette source. Behind the source runs the Géronstère stream with water from, among others, the Géronstère source. The water of the Barisart source joins this stream and flows down the slope towards the city of Spa. About one kilometre to the southeast lies the Géronstère spring and about 900 metres to the southeast lies the Pouhon Pia spring.
