The new initiative combines the social hostelling experience with small-group adventure tours.
Hostels and G Adventures have partnered to launch 'Roamies', a style of travel for 18-35 year olds that offers a collection of 38 tours across 15 countries.
The trendiest of hostels are included in the itineraries, serving as bases to hang out and kickstart adventures.
Tours kick off from May 2022 and went on sale on December 8, 2021. Each tour will host between 16 and 24 travellers, and the partnership is expected to launch more tours across further destinations in the future.
'Roamies' are designed for independent adventurers looking to take part in the social side of hostel travel, and span short breaks of five days to longer 34-day adventures.
G Adventures' founder explained: ?We've always had great respect for Hostelworld - it's an amazing company with an incredible commitment to the advancement of travel, a quality we appreciate and share. The pandemic gave us the opportunity to act like a start-up again.
"As we learned more about Hostelworld?s business, we realised there was an opportunity to create something special by bringing our brands together to create the perfect mix of backpacking and organised travel.
Trips start from ?149 for a three-day adventure, with the five-day 'Peruvian Coast: Seafood, Sandboarding & Dune Buggies' starting from ?449 per person and the 17-day 'Gotta-See Europe: Germany, Austria, Italy - Amsterdam to Rome' tour from ?2,099.
