Despite recent calls to include children in tourism research, the trend of overlooking children's perspectives and experiences remains pervasive (Gram, O'Donohoe, Schänzel, Marchant, & Kastarinen, 2019; Poria & Timothy, 2014). This is a lost opportunity, especially in today's anthropocentric context, as children can offer insightful perspectives on human-nature relationships, and possible lessons for cultivating responsible human connections to, and coexistence with, non-human nature (Merewether, 2019). This research note emphasizes the importance of 'knowing with' children. Based on preliminary findings from a study that looked at nature-based proximity tourism and family nature walk experiences using sensory ethnographic methodologies, we show the value of considering children as tour guides. More specifically, we adopt a relational approach to engaging children's experiences in the world to illuminate under-explored and under-appreciated modes of knowing with non-human nature. Furthermore, we encourage future research that considers children not as a 'state of becoming' or as 'the future', but as influential actors within the present of tourism research (Carpenter, 2015; Leonard, 2019).
