We had an amazing time driving the caravan around the island for a few days over the winter holidays! We got very lucky with the sunny weather, so even though the shower wasn't working on our trip, we were still able to get reasonably clean swimming in the sea every day.
It was very much like camping, but more mobile and more sheltered, and I loved that we were basically able to park anywhere we wanted to sleep the night. But generally, we looked for spaces near the water for great views and morning swims. Also, there's no "washroom", so it's more like wild camping in that aspect.
Quick note: If you're traveling around any local holidays, make sure you plan ahead with groceries as we had some days around December 25, 26 when literally no supermarkets were open, even though it says open on the maps. Also make sure you double check there is Butane for the stove before you hit the road, we had one night where we had to find a restaurant last minute because it was empty.
Thanks Julia!
