Nature trails have become very popular and have become the most widespread method of interpreting natural and cultural heritage. This paper presents the result of evaluation research of a nature trail in the High Tatras National Park (Slovakia). The holding power and attention capture of the individual panels were assessed by observation including further analysis of other factors related to the interpretive quality or location of the panels. Evaluation shows that the trail is overloaded with text and does not adequately link the communicated content with the surroundings. The individual trail panels have a relatively low degree of holding power and attention capture. The evaluation reveals the importance of good quality and thoughtful interpretation of natural heritage. Overall, the study also shows the difficulties associated with the use of statistical methods to analyze the effectiveness of selected trail features.
