Nuuksio is home to a significant population of the endangered Siberian flying squirrel, which is rarely seen due to its nocturnal habits.
The park's terrain features deep, moss-covered ravines and valleys that represent remnants of the geological activity from the ice age.
The park's ecosystem includes diverse forest types, ranging from nutrient-rich groves to dry, lichen-covered pine forests.
Nuuksio contains over 80 small lakes and ponds, many of which feature brown, humic-rich water typical of Finnish forest lakes.
The park functions as a protected area designed to preserve the biodiversity of the Uusimaa region's wilderness.
Nuuksio National Park is one of the most accessible wilderness areas in southern Finland, characterized by its diverse terrain of crystalline lakes, rugged rock formations, and dense coniferous forests. The park spans approximately 53 square kilometers and serves as a vital habitat for the Siberian flying squirrel, the park's iconic symbol. Visitors have access to over 30 kilometers of marked trails, ranging from accessible boardwalks to more challenging forest paths. The landscape is dotted with over 80 small lakes and ponds, many of which allow for swimming or canoeing. Several designated campfire sites are maintained throughout the park, complete with pre-chopped firewood. While the park is open year-round, its proximity to the Helsinki metropolitan area makes it a primary destination for those seeking proximity to untouched nature. The terrain is marked by deep valleys and steep ravines shaped by the last Ice Age.
The Haukkalampi area, specifically the rocky cliffs overlooking the lake, offers a quintessential view of the Finnish forest canopy.
Download offline maps before arrival, as mobile reception can be inconsistent in deeper parts of the forest.
Carry a reusable water bottle, as the park features several natural springs and water stations near main hubs.
Check the official 'Excursionmap.fi' service to see real-time status of campfire sites and trail maintenance.
Do not wander off marked trails, as the forest is dense and terrain can be deceptive; avoid swimming in lakes with steep, slippery rock banks without caution.
Open year-round; however, snow and ice conditions may make some trails inaccessible during winter months.
Follow the Leave No Trace principles: all trash must be carried out, pets must be kept on a leash, and fires are permitted only in designated stone-ringed pits.
