Last Saturday on our CAS hike with the school, I spotted this snake on the side of the trail. We were walking in the hills above the village of Slavkovica just north of Cacak. It immediately hid under a rock and I had a hard time getting it out to get a picture of it. It turned out to be a viper, which I didn’t even know they were found in Europe. It is widespread and thankfully the venom is not that strong and bites are rarely fatal. There are several anti-venoms and it will make you sick and if left untreated could result in death. I wouldn’t take any chances and immediately seek medical help.This might be the Balkan peninsula sub species of Vipera berus.
