Alastair Campbell, managing director, said Wilson had made a “tremendous contribution” in growing the companies since they were acquired by G Adventures following the collapse of All Leisure Holidays Group in December 2016.
“[Wilson’s] commitment to assisting us through the transition process has been invaluable. Colin leaves with our very best wishes for the future and enormous thanks for his contribution to our continued success,” Campbell added.
Wilson said: "Once the transition was bedded in it was always my intention to firstly take a proper break and then look for a new challenge.
“It has been incredibly fulfilling to help lead this business but the time is now right to seek the next opportunity. This I intend to do after a break.”
