The iconic bright red double decker tourism bus has made it to Cádiz, and the service is every bit as competent as it is all over the world. The City Sightseeing Hop On Hop Off is especially good for those travelling with kids, as it allows you to see plenty without tiring their legs out and having to deal with that. The tours are available in 16 languages, and tickets cost €12.25 for adults, €6.13 for kids. Strange prices, we know.
