Nuuksio National Park
Flora and fauna
There are two public bus services to Nuuksio, and both of them require a transfer if coming from Helsinki. Check schedules before setting off, as services are quite limited.
To get to the eastern side of the park, take the commuter train S, U, E or L from the Central Railway Station to Espoo station, then transfer to bus 85/85A. Get off at Nuuksionpää (85/85A) if going to the main visitor centre at Haukkalampi, or at Kattila (the 85A terminus) if going to the second visitor centre. From Nuuksionpää, it's a 2 km stroll to the park entrance.
To get to the southern side of the park, take the trains A, E, U, S, L or Y to Leppävaara and transfer to bus 28. Buses 28K, 28T go to Hotel Siikaranta on the western shore of Lake Siikajärvi, while bus 28A goes to Siikaniemi on the eastern side.
To get to the rarely visited western side, take a private Pohjolan Liikenne  bus to Tervalampi and walk several km.
Entry to the park is free.
The only way to get around is by hiking. A number of well-signposted trails are available, while hardcore hikers can head out into the bush and stay at one of the many campsites. The Yellow Route, from Siikaranta or Siikaniemi to Nuuksionpää, is a particularly pleasant and representative 5-km walk across the southern half of the park.
An information cabin near the main entrance (as well as the Helsinki tourist info) has simple free maps, or invest 10€ in a detailed topographic map of the area.
Eat and Drink
No food or water is available in the park, so bring everything you need. Making an open fire is allowed at the designated fireplaces near the campgrounds, so bring some sausages and have a picnic.
Several wilderness lodges can be rented cheaply, but they're popular so advance bookings are essential. You will also need to bring your own sleeping bags.
There is also one full-service hotel just outside the park.
Camping is permitted only in four designated campgrounds in the park. None have any no facilities, but open fires are allowed.
Eat & Drink
Apart from vipers and the very remote chance of meeting a bear, there is little dangerous fauna in the park. If you don't have a compass and orienteering experience stay on the main trails.
