The Mountain region occupies the northern part of the county.
The rivers Prahova, Teleajen and Doftana with their north-south directions fragment the highlands into several massives well individualized with obvious features.
The Bucegi Massif, with its important landscape and with heights of 2000-2500 m, is fragmented between Prahova, Dâmboviţa and Braşov. From this massive, in Prahova you can find the eastern part of it, with the spectacular steep from Sinaia and Busteni. On this side of the massive are the Peaks Coştila, Caraiman, Jepii, Furnica, Vârful cu Dor, Vânturiş; văile Claia Mare, Claia Mică şi Colţii Morarului, having a ruiniform relief.

The Baiului Mountains, ranging between Prahova, Azuga and Doftana Valleys, are composed of a main sinuous culmination with north-south general direction. Along it, are enumerating the greatest heights: : Neamţu (1923m), Rusu (1902m), Cazacu (1753m), Baiu Mare (1895 şi 1908m), Gagu Mare (1660m). From the main culmination, secundar peaks fan out to west and east, with the height of 1400-1500m and 1100-1200 m, representing remainings of old erosion platforms - Setu and Predeal.
A characteristic note of the Baiului Mountains is given by the creeks and small valleys at the head of torrential streams and pastures carried at over 1500m high. More details at www.inbucegi.ro
Grohotiş Mountains occupy the space between Teleajenului and Doftanei valleys. Their main peak, situated in the extension of the Bratocea peak from the Ciucas Massive, groups the greatest heights: Babeş (1684m), Grohotiş (1767m) and Sf. Ilie (1588m). From this peak emerges to the southeast the Nebunului Peak, between Teleajenului and Crasnei valleys, a string of knolls separated by saddles. To the south-westthe peak continue to the peak Radila Mare (1490m), where it bifurcates embracing Obarsia Vărbilăului: Trifoiu Peak (1372m), continue with Plaiul Serban Voda and the Culmination Păltineţu with Clăbucet (1384m) and Păltineţu (1317m). The peaks are usually rounded and shows, in places, bridges smooth as Mount Bobu Mare (1757m) and Mount Setu (1450-1500m).
The Ciucaş Massif is the second prominent massive in Prahova County. Although smaller than Bucegi, it shows its geographical personality through its heights over 1800m (Ciucaş with 1954m in Bratocea and Gropșoare with 1883m in Zaganului) and its ruiniform relief with a particular note of attraction, through the variety of towers , isolated or bundled rocks, forming bizarre pyramids, tusks and mushroom-shaped rocks.

Between Teleajen and Telejenel rises the little massive Clăbucet (1460m) separated from The Ciucaş by a wide saddle carved by erosion in less resistant formations (clay-marl shales).
Tataru Mountains stretch at east of Telejenel and are presented as a monotonous culmination, but devoid of picturesque, with heights of about 1400m. From it emerge secondary peaks, like some buttresses. Maximum heights are, from north to south, Tataru peaks (1476m), Mănăilă (1407m) and Crai's Peak (1473 and 1502M). At the southeast of Crai's Peak takes place a bump corresponding to Zmeuretului Mountains (1136m), which is presented as a lower rung of the mountains, in direct contact with the Carpathian hills.
