Karlovsko Praskalo, Waterfall in Central Balkan National Park, Bulgaria.

Karlovsko Praskalo is a waterfall on a small tributary of Stara Reka in the Central Balkan National Park. It lies at about 1,400 m on the southern foot of Zhaltets Peak, roughly 10 minutes from Vasil Levski Hut. The water falls about 25 m.

Karlovsko Praskalo and the land around it were declared a natural landmark in 1965, the year the Bulgarian state granted the waterfall and its immediate surroundings formal protected status. The designation covers the cascade on a small tributary of Stara Reka, within what later became Central Balkan National Park.

The name links the falls to Karlovo, the town below the Stara Planina slopes: praskalo is Bulgarian for a spray of falling water. The waterfall drops from a small tributary of Stara Reka, the river that runs past Karlovo, so the name ties the site to the valley it drains into.

The site is accessible via a marked trail starting from Vasil Levski Cabin with only a brief walk to reach the viewpoint. Sturdy footwear is important as the path crosses steep mountain terrain where weather conditions change quickly at this elevation.

The waterfall sits at about 1,400 m on the southern foot of Zhaltets Peak, roughly ten minutes' walk from Vasil Levski Cabin, on a small tributary of Stara Reka. The Bulgarian name means Karlovo Splash, tying the fall to the town of Karlovo below. The water drop is about 25 m high.
