The brand, launched nine years ago offering day tours as part of larger itineraries, is, Intrepid believes, ideally positioned as a gateway to its longer-form product.
Passenger numbers in 2017 were up 62% on 2016 to 172,000, with the brand on course to achieve 295,000 passengers this year (+72%), said Thornton.
Intrepid has also pledged to double investment in Urban Adventures, targeting one million passengers by 2020.
Thornton told TTG Urban Adventures was finally “coming of age”.
“We always believed it had great potential and we’ve invested in it a lot over the last few years,” he said. “If it continues to grow, it’s quite possible it could become the largest chunk of our business.”
Intrepid now offers more than 1,200 Urban Adventures itineraries across around 100 countries.
