#LOSTMTNS started in 2016 as a group of outdoor enthusiasts in the Blue Mountains sharing their canyoning, climbing, bushwalking, and trail-running adventures on Instagram. Growing into a passionate community, they adopted the #lostmtns hashtag to showcase the region’s hidden gems. Committed to mental health, #LOSTMTNS encourages youth to connect with nature for healing, resilience, and stress relief. They actively support local Blue Mountains businesses through tourism and community engagement while promoting bush awareness, Leave No Trace ethics, and respect for the environment to protect this unique landscape.
