Is Spain safe for visitors/backpackers?
It mostly is. Crime rate is not too high. The highest risk for visitors is probably pickpocketing in big cities’ tourist areas, be aware of your pockets in those places, that’s all it takes. The backcountry is safe as far as humans go. There are not many dangerous wildlife either, just the occasional poisonous snake or spider. Spiders are not a big concern while snakes may be. A few of them are poisonous and at least one has a pretty powerful venom though not necessarily lethal. As usual, they’re shy and will move away but may bite if threatened. Not a big deal anyway as there are not many casualties to snakes. Big mammals don’t abound and are not a concern. Wild boars might pose a threat if injured but they’re not supposed to be if you’re not hunting them. They say there are a few bears left in the northern mountains but nodoby knows for sure. Shame.
