Don't come here looking for peace and quiet in summer – this mega-campground at the Terme Čatež resort is chockers with families thanks to masses of kid-friendly facilities including playgrounds, sports courts and an animation program. Not got a tent? There are family-sized tepees plus a 'Pirates Bay' complex: bungalows built over the water in the middle of the campground's lake.
Rates include day-long passes to the thermal baths. Outside of holidays, expect more breathing space.
