Labanoras Regional Park protects the landscape of Labanoras Forest and its lakes. It is the largest regional park in Lithuania, not far behind the largest protected area in Lithuania - Dzūkija National Park. Labanoras Regional Park was established to preserve: 

• the particularly valuable Labanoras forest and lake area with Aisetas, Kertuojai, Lakajai, Rašia, Stirniai and other lakes, the Beržalotas raised bog;
• cultural heritage values, including urban and ethnocultural complexes, burial mounds and others;
• the stability of the natural ecosystem, biota components, unique flora and fauna, natural fish migration routes and spawning grounds.

The regional park is situated in the transition zone of the glacio-fluvial landforms, between the hills of Baltic upland strip and the hills of the northern Nalšia (Švenčionys) uphill strip. The park also contains Šventoji-Žeimena watershed ecosystem and one of the largest in Lithuania laky forests with the valuable from the urban perspective Labanoras town. The landscape of the regional park is characterised by the unique objects of natural and cultural heritage, and large recreational and educational tourist potential.

Labanoras Regional Park is classified under the top category from the perspective of exceptional value of the landscape. The landscape diversity of the Labanoras regional park is determined by the following major landscape types: forested region of glacial lakes (systems of tunnel valleys), groups of forested small lakes, agrarian lakes region, forested laky swampy waterholes, shallow forested terrace valleys, forested glacio-fluvial old valleys, forested undulating glacio-fluvial elevations, forested undulating glacio-fluvial plains, forested glacio-fluvial hills, forested morainic uplands and ridges, agrarian morainic uplands, forested swampy waterholes, and ethno-cultural settlements.

These are the territories of European Community importance (code, title) found in the park: 3130 Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or of the Isoėto-Nanojuncetea; 3140 Hard oligo-mesotrophic waters with benthic vegetation; 3150 Natural eutrophic lakes with Magnopotamion or Hydrocharition – type vegetation; 3160 Natural dystrophic lakes and ponds; 3260 Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation; 6230 Species-rich Nardus grasslands, on silicious substrates in mountain areas (and submountain areas in Continental Europe); 6410 Molinia meadows on calcareous, peaty or clayey-silt-laden soils; 6510 Lowland hay meadows; 7110 Active raised bogs; 7140 Transition mires and quaking bogs; 7230 Alkaline fens; 9010 Western Taiga; 9080 Fennoscandian deciduous swamp woods; and 91D0 Bog woodland. 

The total number of plant species is 1,020, of these 8 are protected by the European Community, 67 are included in Lithuania’s Red Data Book. The total number of animal species is 1,669.
