Founded by experienced adventure guide and nature therapy practitioner Lisa Murphy, Big Heart Adventures creates transformative walking and wellness experiences that encourage a deeper connection with nature, self and community. Based in South Australia, the team offers guided hikes, wellness walks, forest bathing sessions and multi-day adventures across Australia and beyond, all designed to support mental wellbeing, confidence and personal growth.
Lisa’s approach combines mindful nature immersion with adventure, helping guests slow down, reconnect and feel inspired by the landscapes around them. Experiences cater to a wide range of abilities, from beginners to experienced trekkers, with a strong focus on inclusivity, sustainability and authentic connection.
Whether exploring the Adelaide region, Flinders Ranges or international destinations, travellers can expect small-group experiences that blend movement, mindfulness and meaningful moments in nature. We love the Forest Bathing sessions in Adelaide at Himeji Gardens, and in Belair National Park in the Adelaide Hills.
