I'm looking to find long term parking for my camper within about 10 mile radius of Kotor old town. The camper will not be used during my time in Kotor.
There is a parking area called "Green Field" here: https://maps.app.goo.gl/PAkPBH7zbwzJ4bVR8 I am not sure they can host a campervan, but you could check with them. Tel 068 22 11 11
If you use street view on google maps you will see how the building looks like.
