The best time for caravan travels in Estonia summer. The days are long, so it is safer to drive and you'll have more time to take in the gorgeous nature views, and to go camping. As Estonia has low population density, i.e. we only have 30 inhabitants per square kilometre, it easy to find privacy in Estonian nature.
There are plenty of campsites that are suitable to folks travelling in caravans and camper vans in Estonia; the highest number of such campsites can be found in Western and Northern Estonia, and on our largest island Saaremaa, but be sure to visit Southern Estonia as well! Most campsites are open from May to October.
