Before we went on our road-trip to Croatia and Montenegro, we googled "wild camping" in those countries. We love to wild camp – no annoying tourists, no tiny spaces, no disgusting showers. We prefer to be on our own, bathing in a river or under our solar shower (or not at all, after spotting a snake in the river). We love to hear the sounds of nature and not the camping ground neighbours.
So we're always on the search for good spots, to avoid official camp sites, if it's possible. Sometimes it isn't and when you google "wild camping in Croatia/Montenegro" you'll find different answers. Officially it is forbidden in both countries – but some say don't do it in Croatia (and we heard some stories of our friends, who got caught, which was expensive). Some say it's ok to wild camp in Montenegro, if you're not in a national park. We had so many different answers... so we thought we'll just decide on site.
And here is our opinion: Just do it – if you find a nice place, not next to the tourist areas, a little bit hidden, just go for it. We checked google earth to see where those gravel roads are going and if there are houses on the end. Olive groves are also pretty nice, pull-in/picnic areas on passes always have stunning view. Ruins, old churches and castles are a good choice as well. Don't stay the whole day, leave early and please do not leave your trash !!! and you're good.
If there're locals around, ask them, if it would be ok to stay the night and in our case – they were super nice and ok with it, as long as you don't make a fire. Sometime you get lucky (or more drunk, than lucky) and get invited to their homes and can stay the night on their property. Which is awesome, when you are in a national park and not so sure about wild camping or not.
If you need tips or the exact spots, where we wild camped – don't be shy and write me a mail. I'm happy to let you know, where we went as long as you don't leave your trash. :)
