Technical Details: A Romanian Premiere
The dam is a massive concrete structure, striking for its elegant curve and strategic placement.
- Height: 108 meters, ranking it among the tallest in the country.
- Type: It was the first dam in Romania built with a double-arch structure and a perimeter joint, an innovative technical solution for its time (completed in 1971).
- Length: The crest stretches across 455 meters.
- Purpose: Its primary role is providing drinking water for the cities of Câmpina and Ploiești, as well as generating hydroelectric power.
The reservoir covers approximately 200 hectares and is surrounded by lush, protected vegetation.
- Aquatic Fauna: It is a paradise for catch-and-release enthusiasts, known for healthy populations of pike, perch, chub, and trout.
- Surroundings: The shores are guarded by ancient beech and fir forests. It is not uncommon for brown bears (see more) or wild boars (see more) to descend to the water's edge at dusk.

Like any deep, mysterious lake, Paltinu has its share of folklore. Local legends speak of the "Serpent of the Lake." It is said that a giant snake lives in the cold depths, guarding the dam. While likely an exaggeration of the massive catfish (somn) that dwell on the bottom, the story adds a mystical charm to the area, especially when the morning mist rises from the surface.
Fun Facts for Travelers
- The Shifting Colors: Depending on the light and season, the water changes from an intense emerald green to a turquoise that rivals Alpine glacial lakes.
- "La Tocile" Gorge: The dam is built in a narrow gorge called "La Tocile," a name given by locals due to the sharp, asymmetrical slopes of the mountainside.
- Fishing Hotspot: While swimming is strictly prohibited due to dangerous currents and extreme depths, it is considered one of the best "predatory fish" spots in the Prahova region.
Frequently Asked Questions: Paltinu Dam (Barajul Paltinu)
1. Where is the Paltinu Dam located?
The dam is located in the Doftana Valley, Prahova County, approximately 25 km from the city of Câmpina and 100 km from Bucharest. It sits at the junction of the Baiului and Grohotiș Mountains.
2. Can I swim in the Paltinu Reservoir?
No. Swimming is strictly prohibited. Because it is a primary source of drinking water and a hydroelectric site, the currents near the dam are extremely dangerous, and the water depth reaches over 100 meters.
3. Is fishing allowed at Lake Paltinu?
Yes, fishing is a very popular activity here. The lake is famous for pike, perch, and trout. However, you must ensure you have the valid local permits required for the Doftana Valley region.
4. Can I walk across the dam?
Access to the crest (the top of the dam) is usually restricted for security and technical reasons. However, there are several spectacular viewpoints along the main road that offer a full panorama of the structure and the emerald lake.
5. What makes the water look so green?
The distinct emerald color is a result of the water's purity, the depth of the reservoir, and the reflection of the surrounding dense deciduous forests. The color is most intense during late spring and early autumn.
6. Are there camping areas nearby?
Yes, there are several designated camping spots and "glamping" sites along the Doftana Valley. For those seeking comfort, the nearby village of Traisteni offers many traditional guesthouses.
7. Is the area safe for hiking?
Yes, but be aware that you are in a mountainous region. Since wild animals are unpredictable, always hike in groups and stick to the marked trails leading toward the Baiului Mountains or the Glodeasa Virgin Forest.
8. What is the "Legend of the Serpent"?
It is a local myth about a giant creature living at the bottom of the lake. While no "monster" exists, the lake does house very large catfish that can grow to impressive sizes, which likely fueled these stories over the decades.
