The park contains the Kyynäränharju ridge, a natural land bridge separating two large lakes.
Korteniemi Heritage Farm operates as a living museum, maintaining heritage crop varieties and landrace breeds.
The park serves as a protected refuge for the Siberian flying squirrel, an indicator species of old-growth forest health.
The area features extensive duckboard paths designed to protect sensitive peatland ecosystems from foot traffic.
The park's water quality is high, supporting diverse populations of perch, pike, and roach.
Archaeological findings in the region indicate human activity dating back to the Stone Age.
The terrain is shaped by eskers, which are long, winding ridges of stratified sand and gravel deposited by glacial meltwater.
The park hosts annual events dedicated to traditional scything and haymaking at the heritage farm.
Liesjärvi National Park is characterized by its extensive lake shoreline and deep coniferous forests within the Tammela region of Finland. The park features over 30 kilometers of marked trails, including paths that traverse narrow esker ridges surrounded by water on both sides. The Korteniemi Heritage Farm serves as a focal point within the park, preserving 19th-century agricultural traditions and organic farming techniques. Visitors can access a variety of environments, ranging from bog boardwalks to old-growth spruce forests. The park’s geography is shaped by the depositional landscape formed during the last glacial retreat. Several lakes, including Liesjärvi and Kyynäräjärvi, provide extensive recreational water access. Infrastructure includes designated campfire sites, tenting areas, and rental cabins for overnight stays. The park is integrated into the larger Häme Lake Uplands trail network.

Bring waterproof footwear, as boardwalks can be slippery and trails may be muddy during spring thaw.
Pack drinking water, as natural sources must be boiled or filtered before consumption.
Check the local forest fire warning index online before planning to use any designated campfire sites.
Do not wander off marked trails, as the terrain can be deceptively marshy and navigation is difficult in dense forest.
Practice leave-no-trace principles; do not pick protected plants; keep dogs on a leash at all times.
