The Cavern Lake Cave Trail is a short trail to Cavern Lake Cave, about 70m long. It ends at a viewing deck providing a view to the mouth of Cavern Lake Cave. There is a stream coming from the cave mouth, which makes it an impressive sight. It is not possible to enter the cave as it an active river cave, and rather dangerous. It is necessary to wade through cold water and there is the danger of flooding, so cave visits are not advisable.
