Hop-on, hop-off round trips run from June through to September. That means you can get on or off at any route stop throughout the day. One route circles the heart of the city (12.5km long, red route, departs at 10:00, 12:00, 14:00 and 16:00), while the other takes you in a wider circle around the city centre (32.5km – green route, departs at 12:00 and 15:00). The Departing point is at Bakačeva street, near the Cathedral at Kaptol. An audio guide in 8 languages tells you about the sights you drive past. Tickets cost 70kn for adults, 35kn for children between 7 and 18, while kids under 7 are free of charge. Buy your tickets from the driver or in the ZET office at Petrićeva 4 which is only one minute walk from Ban Jelačić Square. Another ZET office is located at Ozaljska 105.
