Plitvice Lakes National Park

(Croatian: Plitvička jezera) is the oldest and

the largest national park in Croatia.

The national park is world famous for its 16

lakes arranged in cascades and waterfalls.

These lakes are separated by natural dams

of travertine rock, which is the result of an

interplay between water, air and plants.

.

Lake Vrana (Croatian: Vransko jezero) in

Dalmatia is the largest lake in Croatia. It is a

designated nature park, a kind of protected

area in Croatia. It is an ornithological

reserve, an almost untouched natural

habitat of birds.

The area of the lake is about 30 square

kilometres, but it is only 4 metres deep.

Lake Vrana, in the centre of Cres, is a fresh

water lake, that supplies islands Cres and

Lošinj with drinking water.

The lake is 1.5 km wide, 7 km long and it is

cryptodepression. Its bottom reaches a

depth of around 60 m below the sea level,

but its surface lies 14 m above it.

First it was thought that the water in the

lake was linked to some mainland source by

underground streams, but its water

originates from rain.

Red Lake and Blue Lake (Croatian: Crveno i

Modro jezero ) are two karst lakes located

near the town of Imotski in the south of

Croatia. They lie in deep sinkholes possibly

formed by the collapse of large

underground caves.

Water depth varies over seasons. At the end

of summer, Blue Lake may completely

disappear.

The average water depth of Red Lake is 290

meters.

Adriatic Sea

The Danube River (Croatian: Dunav), the

Drava (Drava), the Sava and the Kupa are

long, slow and muddy. They meander

through the Panonian plain.

mouth of the river of Drava (Croatian:

Rivers that flow to

the Adriatic Sea

(the Zrmanja, the

Krka, the Cetina,

the Neretva…) are

short, fast and

clear. They form

gorges in the

Dinaric Alps.

Krka waterfalls

In the karst areas of Croatia (the Dinaric

Alps), rivers may disappear through

sinkholes, continuing underground.

Subterranean rivers (the Gacka, the Lika,

the Dobra and the Pazinčica) are rivers that

run partly beneath the ground surface.

These subterranean rivers are often

connected to submarine karst springs in

the Adriatic Sea that are called vrulje in

Croatian.
