Joe Ponte, Explore managing director said: “Today’s travellers are looking for authentic experiences over fly-and-flop holidays and they’re becoming more adventurous in the destinations they’re choosing to go to, from the Middle East to lesser-travelled Europe.

“We’re seeing huge interest in experiential travel across the board, and our new Discovery and Wildlife programme has been tailored to fit the needs of these travellers and their growing thirst for adventure.”
