Camping/Cabins in Croatia?
Hi! I want to stay in Croatia for a few days, specifically near Hvar. All of the hotels seem to be booked as this is the busy season, so my friend and I thought cabins may be cheaper and more interesting. We looked into the various campsites, but everyone looks on top of each other, and privacy is very important to me.
Can anyone point me to web sites for cabins (or even tent sites, as long as its safe and your nearest neighbor isn’t breathing down your neck) near or on the ocean?
Thanks!!!!
I found a few sites, not sure if you’ve been to them or not. Your trip sounds AWESOME!!!!! Have fun!!
