This article examines how safety is understood and practised by wilderness guides leading nature excursions with international customers in Finnish Lapland. Commercial nature tourism services in Lapland are not considered adventure-oriented since risk-taking is not an integral part of the guided services. The study shows that even though perceived as low-risk activities, risks are present in a significant part of the everyday actions in commercial nature tourism services. Thus, commercial nature tourism forms a rich context to study the sustainability of contemporary safety practices since it forms a specific, guide-dependent sector of the tourism industry. The discussion further underlines the complexity of safety issues within the industry and the importance of holistic approaches.
