Legends of the Deep: The Giants of Tarnița
One of the most intriguing aspects for any visitor is the local legend of the "Giant Fish." For decades, locals and divers working on the dam have shared stories of massive catfish (somn) measuring over 3 meters long living at the bottom of the lake. While largely a myth, these tales of "monsters in the deep" add a layer of mystery to the emerald waters, making every boat ride feel like a small adventure.
Biodiversity & The Surrounding Wilderness
The lake is cradled by dense forests of beech and fir, creating a rich ecosystem:
- Aquatic Life: Beyond the legends, the lake is a prime spot for trout, clean, and perch.
- Forest Fauna: The surrounding Gilău Mountains (see more) are home to deer, wild boar (see more), and various birds of prey that can often be seen circling the peaks above the water.
- Autumn Colors: In late October, the hills turn into a spectacular palette of fire-red and gold, reflecting perfectly in the still water.

- An Engineering Marvel: The Tarnița Dam, completed in 1974, is a double-arch dam standing 97 meters tall. It was a massive feat of engineering for its time.
- The "Dragon" Shape: From high above—specifically from the Piatra lui Lucaci viewpoint—the lake looks like a giant emerald dragon winding through the mountains.
- High-Altitude Swimming: Tarnița is a hotspot for "Transylvania Open Water" swimming competitions, attracting athletes from all over Europe.
FAQ: Visiting Lake Tarnița (Cluj County)
1. Is swimming allowed in Lake Tarnița?
Yes, swimming is permitted and very popular during the summer months. However, keep in mind that the water is quite deep (up to 70 meters) and stays relatively cool even in August. There are no official lifeguards, so swimming is at your own risk.
2. How do I reach the lake from Cluj-Napoca?
The most convenient way is by car. The drive takes about 45–60 minutes (approx. 30 km). You head towards Gilău on the DN1/E60 highway, then follow the signs toward Someșul Rece or Mărișel. Public transport to the lake is limited, so a rental car or a taxi/rideshare is recommended.
3. Can I rent kayaks or boats?
Absolutely! There are several rental points along the shore, especially in the area known as "Coada Tarniței." You can rent:
- Kayaks and Canoes
- Stand-Up Paddles (SUP)
- Electric Boats (Note: Motorboats with internal combustion engines are generally restricted to protect the environment).
The most iconic view is from Piatra lui Lucaci. It is a moderate hiking trail that starts near the dam. The hike takes about 1.5 to 2 hours to reach the top, but the panoramic view of the "emerald dragon" (the winding lake) is well worth the effort.
5. Are there places to eat or stay nearby?
Yes, the area is dotted with private villas and guesthouses (pensiuni). Many locals rent out cabins for the weekend. For dining, you will find a few restaurants and terraces near the main access points, but it is always a good idea to bring some water and snacks if you plan on hiking.
6. Is Lake Tarnița crowded?
During summer weekends, the lake is a favorite spot for locals from Cluj, so it can get quite busy. If you prefer tranquility and easy parking, try to visit during the weekdays or in the early morning.
