Slovenia's thermal spas, fed by natural mineral springs, are located next to campsites, making them convenient for travellers in motorhomes and caravans. The six featured sites include Terme 3000 (around 430 pitches, open year-round), Terme Banovci (around 100 pitches), Terme Čatež (30–50 motorhome pitches), Thermana Laško (around 10 pitches, usually up to three nights), Terme Olimia (around 50 pitches) and Terme Ptuj (around 200 pitches, seasonal opening). Most campsites offer electricity, sanitary facilities and grey water disposal; some accommodate oversized motorhomes.
