Žygis, Marijampolės apskritis
A 410-metre boardwalk trail leading from the Žuvintas biosphere reserve visitor centre across reed beds on the southeastern shore of Žuvintas Lake, reached first by a short gravel path before the wooden planking begins. It is a quiet, low-impact route into the reserve - dogs must stay leashed and visitors are asked not to pick plants or make noise - ending at the reserve's bird-watching observation tower. Open 8:00-20:00 without special permission.
