The collaborations will offer customers a new range of holiday experiences including safaris, expeditions, camper trips and worldwide backpacking tours.
The move comes as the active leisure travel agent plans to relaunch with a new look and product offering for 2022 at the National Outdoor Expo in Birmingham this weekend (19/20 March).
Whereabouts will offer campervanning, backpacking, hiking and trekking, volunteering and wildlife trips ranging from five to 45 nights in duration.
Sales manager Andy Myrlea said: "I’m excited about this brand having worked in travel for over a decade. With the closure of STA, where I spent nearly 10 years, there is a gap in the market for adventure and thrill seeking travel – targeting young and the young at heart."
