Swimming is not possible in this lake!
The water of the lake flows steeply down a kilometer-long concrete canal into the Plužna hydroelectric power station, which has been in operation since 1931.
The film Narnia was filmed on this stream at the mouth of the Soča river.

Jurski apnenci v dolini, ki so slabše prepustni, so omogočili nastanek jezer. Uradno jih je sedem, v dolini pa je še nekaj manjših jezerc in mlak. Voda iz Doline Triglavskih jezer odteka po notranjosti kraškega sveta in privre na dan v mogočnem slapu Savica.
V globeli med Vodnikovim Vršacem (2194 m), Kanjavcem (2568 m) in Poprovcem (2495 m) opazimo tri jezera.
Ob južnem vznožju Vršaca je Jezero pod Vršacem ali Jezero v Podstenju (1991 m), ki ga štejemo za prvo Triglavsko jezero; večino leta ga pokriva snežišče. Jezero je dolgo 90 m, široko 60 m in globoko do 5 m. Ob vznožju pod Zasavsko kočo je Mlaka v Laštah (1994 m), ki se ne šteje med sedmera jezera.
Malo južneje v bližini poti, je precej večje Rjavo jezero (2006 m). To je drugo Triglavsko jezero; dolgo je okoli 150 m, široko okoli 100 m in globoko do 10 m. Ime je dobilo po rjavkastem obrežju, ki se pokaže poleti, ko gladina vode upade.
Po 15 min pridemo do Zelenega jezera (1988 m), ki je tretje Triglavsko jezero. Dolgo je okoli 100 m, široko do 80 m in globoko le do 2 m. V jezeru rastejo alge, zato je zelene barve. V vodi živijo alpski pupki. Tu je tudi najvišje slovensko rastišče vodne zlatice z belimi cvetovi na vodni gladini. Pri jezeru se odcepi pot na Hribarice in na Kanjavec ter naprej do Tržaške koče na Doliču.
Jezero v Ledvici (1831 m), tudi Veliko jezero, je četrto Triglavsko jezero. Je največje in najglobje; dolgo je 320 m, široko 120 m in globoko 15 m. Je ledvičaste oblike, vendar naj bi dobilo ime po skalni škrapljasti grbini Ledvici na severozahodni strani jezera. Jezero počasi zasipavajo obsežna melišča izpod Zelnarice. V okolici jezera vidimo značilne kraške pojave: žlebiče, razpoke in kotanje. Vmes rastejo rušje in macesni samotarji.
Dvojno jezero (1676 m) se imenujeta peto in šesto Triglavsko jezero v bližini Koče pri Triglavskih jezerih. Spomladi, ko se topi sneg, sta jezeri združeni v eno; med njima je le nizka naravna pregrada. Peto jezero je dolgo 120 m, široko 80 m in globoko 6 m, šesto pa je dolgo 100 m, široko 70 m in globoko 8 m.
Črno jezero (1294 m) je sedmo, zadnje med Triglavskimi jezeri. Leži v kotanji ob južnem vznožju Stadorja (1688 m) za robom Komarče. Obdano je s smrekovimi gozdovi, ki mu dajejo temno barvo. Jezero je dolgo 150 m, široko 80 m in globoko do 6 m. V njem živi endemična podvrsta alpskega pupka.
Dolina Triglavskih jezer je zanimiva tudi po površinskem kraškem svetu z značilnimi kraškimi pojavi. Voda že tisočletja razjeda apnenčasto površino. Na od ledenika uglajenem površju so nastali žlebiči, globoke razpoke, kotanje in ozka žrela, ki segajo v notranjost skalovja. Gozdna meja je med 1600 in 1800 m. Malo pod gozdno mejo rastejo na malih travnih zaplatah med kamenjem rušje in redki macesni; navzdol po dolini, ko so boljši pogoji, pa je drevja več.
Najlepši okras Jezerske doline pa je izjemno rastlinstvo. Med kamenjem in gruščem na meliščih rastejo okrogolistni mošnjak z vijoličastimi cvetovi v grozdih, alpska velesa z belimi posamičnimi cvetovi, belacvetni julijski mak, alpska madronščica z vijolično oranžnimi cvetovi in pirenejski kamnokras z dišečimi rožnatimi cvetovi. V okolici Dvojnega jezera raste redka rapontika, do meter in pol visoka rastlina iz družine košaric s cevastimi vijoličastimi cvetovi. Po dolini rastejo še rumenocvetni Hacquetov ušivec, zlati klobuk, kranjska lilija, Sternbergov in divji klinček, rumeni svišč (košutnik), Kochov in Clusijev svišč, avrikelj (lepi jeglič), črna murka, planinski srobot in še veliko drugega alpskega cvetja.
Še eno naravno znamenitost zasledimo v dolini. V rdečkastih jurskih apnencih lahko najdemo okamnele lupine amonitov; ti glavonožci so žaiveli v morju pred mnogo milijoni let. Njihove okamnele lupine pričajo, da je v davnini tudi to pokrajino pokrivalo morje.
Bogastvo naravnih pojavov in rastlinstvo so že pred več kot dvema stoletjema privabili v Jezersko dolino mnoge znane naravoslovce in botanike. Leta 1777 jo je prehodil prvi raziskovalec Julijskih Alp Baltazar Hacquet (1739 ali 1740-1815), ko je raziskoval, odkod prihajajo vode Savice. Botanik Karel Zois (1756-1799) je proučeval alpsko rastlinstvo, po njem se imenujeta Zoisova zvončica in Zoisova vijolica. Tudi znani naravoslovec in kartograf Henrik Freyer (1802-1866), kustos Deželnega muzeja v Ljubljani, raziskovalec na področju biologije, geologije in geografije, je svoje delo usmeril tudi na območje Julijcev; znano je, da je bil že leta 1834 v Dolini Triglavskih jezer.
Dolina Triglavskih jezer je bila leta 1924 zavarovana kot Alpski varstveni park. Leta 1961 je bilo zavarovanje obnovljeno v nekoliko razširjeni obliki; zavarovano območje je obsegalo 2000 ha. Triglavski narodni park v današnjem obsegu 84.805 ha je bil zavarovan leta 1981. Osrednje območje parka zajema celotno visokogorje. Meje osrednjega območja so ob poteh in cestah označene s posebnimi tablami.

Tips from the Community
Divje jezero is a karst siphon lake (Vaucluse spring), located approximately 2 km south of Idrija. The type of karst spring - Vaucluse spring is named after the Fontaine-de-Vaucluse spring in the Vaucluse region of Provence in southern France, east of Avignon. Springs of this type are characterized by the fact that water flows to the surface from great depths under pressure through steep channels. The lake lies in a stone cauldron under the hundred-meter cliffs that border this northern edge of the Črnovrška plateau. Divje jezero is also a karst spring, as water flows into the lake from a steeply descending trench, which has been explored to a depth of 160 m so far. Although the lake surface is usually calm, after heavy rains there can be strong eruptions of water, up to 60 m³/s. The Jezernica River flows from Divje Jezero, which is the shortest surface-flowing river in Slovenia and flows into the Idrijca River after 55 meters. The water temperature in the lake fluctuates only between 7 and 10 °C throughout the year. The lake was protected as a natural monument in 1967 and since 1972 has been arranged for visitors as the first Slovenian open-air museum.

The reservoir's water comes from the Glijun Stream, fed by subterranean waters in the Kaning Mountains. The stream is one of the rare karst springs that never runs dry. The lake's water flows via a kilometer-long concrete canal into the Pluzna hydroelectric power plant.

A charming village with a small traffic junction in the lively center, where several restaurants are located. At the edge of the village is a remarkable bridge over the Soca River.

Lake Krn (Krnsko jezero): One of the largest glacial lakes in the Julian Alps – truly impressive! The trail there is challenging, but at the top, a crystal-clear mountain lake with an incredible view awaits you. If you know you're coming to this lake, it's worth packing your swimsuit and taking a dip. Simply fantastic. Great water, great views, and it gives you new energy to keep going.

A small town with a small square where life takes place. There are swimming opportunities around it.

I recommend a visit by bike or on foot. The lake is truly beautiful but at the same time eerie, as we do not know its exact depths. The shortest river, Jezernica, flows out of it, which flows into the Idrijca after a few meters. You start at one of the larger parking lots in Idrija, from where it is about 3km to Divje Jezera. An ideal starting point also for those who visit the city with a camper. On the way to the lake (if we pay attention), we can see the remains of the Italian caves and bunkers.
