With the arrival of warmer weather, Croatia has officially entered the season of the poskok (nose-horned viper), the most venomous snake found in this part of Europe.
Experts warn that the species emerges from winter hibernation in early March, most commonly in coastal and mountainous regions including Dalmatia, Istria and Lika.
Although encounters are relatively rare, caution is advised for anyone spending time in nature.
Specialists stress that prevention is key. When walking through natural areas, hikers are encouraged to make their presence known by gently tapping the ground with a stick or making light noise while moving. This helps alert snakes and reduces the likelihood of a surprise encounter.
It is also important to remain aware of surroundings, as adders are not only found on the ground but can occasionally be seen resting on low branches.
If encountered, the advice is simple, remain calm and slowly move away, giving the snake space.
In the rare event of a bite, immediate medical attention is essential. Victims should reach a hospital as quickly as possible to receive antivenom treatment.
Despite the perceived danger, incidents are uncommon. Rescue services in the Zadar area report only a handful of interventions related to adder bites over the past two decades.
In the past, some communities developed an unusual relationship with snakes. In the Bokanjac area near Zadar, generations were involved in catching and trading snakes, with foreign buyers travelling to the region.
This practice has largely disappeared, but it remains a notable part of local heritage.
There are many myths surrounding snakes, particularly the poskok. Some believe they can jump or behave aggressively without provocation, while others repeat old folklore about different snake species.
However, experts emphasise that such claims are unfounded. As Jana Mijailović from the Croatian Mountain Rescue Service told HRT, misinformation often fuels unnecessary fear, and better public awareness is essential.
Authorities stress that while the poskok is venomous, it is not aggressive and will avoid human contact whenever possible.
The key message is clear: enjoy Croatia’s natural beauty, but remain cautious, informed and respectful of wildlife.
