Yes, I saw snakes some times.
Once, I was on holiday and walking on a small garden path, and right on one of the ancient stone stairs, there was a rather big snake taking a sunbath, probably an Aesculapian snake (from the family of the Culubridae). It is a protected species and nonvenomous. But till my camera was ready, the snake had disappeared in the bushes. One or two days later, I found the exuvia.
Furthermore, I had the occasion to see various snakes in vivaria, zoos, animal presentations, etc., but also dead snakes, killed by road traffic.
