Strict nature reserves of Croatia: Hajdučki i Rožanski kukovi and Bijele i Samarske stijene
What are strict nature reserves in Croatia
A strict nature reserve is an area of land and/or sea where nature hasn’t been changed or has only been slightly changed that is entirely intended for preservation. Any economic and other activities are strictly prohibited.
These nature reserves are intended for scientific research and monitoring of nature. However, these activities must not change the biological diversity and originality of nature or endanger the free flow of natural processes. Visiting is also allowed.
A strict nature reserve is called “strogi rezervat” in Croatian. They are one of nine types of protected areas in Croatia. Strict nature reserves have the highest level of protection, even higher than national parks and parks of nature. [Read: National parks in Croatia PLUS detailed visitor guides]
Croatia has 2 strict reserves:
- Bijele i Samarske stijene (White and Samarian rocks)
- Hajdučki i Rožanski kukovi (kukovi translates as hips)
The facts are these…

Bijele i Samarske stijene
Bijele i Samarske stijene is located near Velika Kapela located on the mountain of Velebit. It includes numerous bizarrely sharp limestone and karst rocks. Some protrude more than 50 meters into the air. Due to many cracks, abysses, and faults, it is not easy to access this area.
Fir, spruce, and beech forests grow on the blocks of stones. The contrast between white stones and dark green trees is stark. Bijele i Samarske stijene was declared a strict reserve of nature in 1985.
The greatest symbol of Bijele stijene is a series of 5 sharp rocks in a row called Prsti (Fingers). They got this name thanks to their shape, which resembles a hand raised to the sky.
Another notable site is a valley with a “chapel” – a space that is enclosed with 50-meter high vertical cliffs reminiscent of an amphitheater. To get there, you will have to pass through a narrow passage under rocks referred to as Slonova brada (Elephant’s Beard).
A hiking trail towards Bijele i Samarske stijene is one of the most demanding and exciting hiking trails in Croatia. Some paths are pretty wild and secured with steel ropes and wedges.
If you decide to take a hike, definitely visit Ratkovo sklonište. It is one of the most original mountain shelters in Croatia built into a semi-cave below the cliff called Šerpas. There is enough space for overnight accommodation of 12 people. A water tank next to the shelter will keep you hydrated. Ratkovo sklonište was named after Croatian alpinist Ratko Čapek who died in an accident in the Alps.
Look out for endangered plant species such as runolist (Edelweiss) or srčanik (Gentiana). Be sure not to disturb the local animal population, which can include bears, weasels, dormouse, or martens. [Read: Endangered animals you might see in Croatia]

Hajdučki i Rožanski kukovi
Hajdučki i Rožanski kukovi includes a group of rocky peaks of peculiar shapes located in the center of Northern Velebit National Park. Peaks are made of limestone deposits and separated by abysses. Some of these peaks rise up to 200 meters high making it nearly impassable. Hajdučki i Rožanski kukovi was declared a strict reserve of nature in 1969.
There is a mysterious pit hidden in the middle of Hajdučki kukovi at 1.475 meters above sea level called Lukina jama (Luka’s pit). Its bottom lies 84 meters above sea level. It is 1.382 meters deep which makes it the 8th deepest pit in the world. An unknown animal from the order of leeches was discovered here in 1994.
Rožanski kukovi is easy to enjoy thanks to the 57-kilometers long mountain path called Premužićeva staza. With an average slope of 10% and the largest slope of 20%, this path is not demanding. It is suitable for hikers of all skill levels. If you decide to take a break, visit a mountain shelter Rossijevo sklonište, located in the heart of Rožanski kukovi below the rock called Pasarićeva kuka.
