The 112-sq-km Čepkeliai reserve, the largest area of untouched nature in Lithuania, is a glorious wet wilderness of bogs, black alder swamps, Cladinoso-callunosa forest and lakes, home to more than 4000 species of animals and plants (including lynx and wolves).
Visits are limited: apply and pay the necessary fees at the Marcinkonys Visitor Centre. Between April and June, visits to the nature reserve are only possible with accredited guides.
