The Cadolles Fondes are located at the end of the Fraguerau gorge, at the confluence of the Gleva stream (in the form of a waterfall) with the Montsant river. The name is due to the large number of ponds of considerable depth carved into the rock by the action of the water.

El Toll de l'Ou is one of the most unique places in Montsant. It is located in the Barranc dels Pélags and usually has water almost all year round. Formed by several pools dug into the rock and joined by small waterfalls, it is a very popular place, especially in spring and early summer. It can be reached from the village of Ulldemolins on the GR-171, passing by the hermitage of Santa Magdalena, in the direction of Pi de la Carabasseta, from where you take a path that goes down to this place. It can also be accessed from La Morera de Montsant following the GR-171.

It is a natural viewpoint, not suitable for people with vertigo, from where we can see a great panorama of the historic Priory, the Sierra de la Gritella and the Sierra de Llaberia. It is accessed from the Morera de Montsant by the Grau dels Barrots. This Degree, of access to the Serra Major, presents some technical difficulties since at some point it has to climb through some bars nailed to the rock. From the steep path we will have to pass over a stone embedded in the crack that separates the rock from the cliff, with the help of an iron railing. This is a point of extraordinary beauty, which will allow us to access the Sierra Mayor from where we can discover the park through the network of signposted paths.

This corner of Montsant is one of the emblematic places of the Natural Park. It is located in the heart of the mountains and can be reached from La Morera de Montsant, either by the Grau de Salfores, or by the Grau de la Grallera towards the Piló dels Senyalets, and from both points to the Pi del Cugat , where you have to take a path that goes down to the Clot. It is an oasis of greenery in the middle of the arid Serra Major, as there is usually water all year round. Contrary to many people's beliefs, in the middle of nowhere, there is a walnut tree, not a cherry tree. The cherry tree that gave the place its name died years ago and a walnut tree was planted in its place. In the past, shepherds used to bring their flocks to drink, and the drinking troughs they prepared for their flocks are still preserved.
