Don't go to Croatia expecting quiet, small family-run campsites. Most sites there are a legacy of the former Communist era, often with well over 1000 pitches. Croatia is also in the grips of the Dutch and Germans so it pays to not have any problems in that respect. There are also very few sandy beaches. So much for the negative side. Otherwise, Croatia has a lot going for it - relatively cheap, generally good weather, lots of picturesque old towns both along the coast and inland.
