The trail which is located in the Plateliai Landscape Reserve offers to explore the relief characteristic to this region, Šeirė forest, the Gaudupis Bog, Lake Piktežeris and Lake Plateliai, as well various species of plants, fungi and animals, including protected. The infrastructure installed along will assist in acquainting with the environment through seeing, smelling, hearing, touching, moving and thinking.

Gaudupis is one of the largest swamps in the National Park. 8 species included in the Red List of Lithuania have been found here.

Lake Piktežeris is an example of a lake turning into a swamp. The eye of the lake still exists reaching up to 16 m in depth, while near the shore – only up to 7 m. The water is sour with slight content of oxygen. Only one fish species lives here – a perch.

A recently renovated viewing platform is available on the coast of Lake Plateliai. The platform is adapted for people with disabilities (visual impairment and movement disorders) and it opens a truly gorgeous panoramic view of the lake, Skarbas (Treasure) Hill known from the old tales and Kumelkaktė peninsula,  which, it is thought, an ancient temple once stood on. The information stand on the platform allows to touch the shape of the lake as well as the shape of islands in it.
