Bradley Walsh & Son: Breaking Dad - Season 4

Bradley and his son embark a 3,000-mile journey through Europe, aiming to experience extremes from the fiery heat of the Mediterranean to the icy tundras of the Arctic Circle. They begin in Croatia, where they swing off the roof of Hajduk Split's football stadium, before diving headfirst into the crystal-clear waters of the Adriatic. The action continues when the pair go head-to-head on aqua bikes alongside a former world champion, before heading to the capital Zagreb to meet a young inventor, who stuns them with his electric creation.

Bradley and Barney say hello to Hungary, where the boys take to Lake Balaton for some high-speed catamaran sailing before sampling some world-famous goulash.

The pair continue their European adventure in Poland, going sightseeing in Krakow before attending an exclusive performance by the Polish National Radio Symphony Orchestra in honour of Poland's most famous composer Chopin.

The boys arrive in Denmark for the Scandinavian leg of their tour. Bradley's fear of heights is pushed to the limit with a visit to an offshore wind turbine.

The actor and his son head to Sweden, where they go head-to-head in a curling competition alongside the country's women's team in Stockholm. The next day, Barney treats his dad to an infamous fishy delicacy for breakfast, then takes him paintballing with a Western twist, and finally lines up a musical surprise for big Abba fan Bradley.

The actor and his son conclude their latest trip by heading to Norway, where Barney has arranged to meet a local adventurer, who dares them to sit in icy water before showing them a spectacular stunt by diving from 20 metres head-first into a lake. They then go to Lillehammer home to sample the bobsleigh run used in the 1994 Winter Olympics, before going into the Arctic Circle to try out one of the world's most northerly surfing spots.
