Instructions and Rules along Herajärvi Trail
Instructions on Exploring Herajärvi Trail
- Running mainly on private land, the Herajärvi Trail is governed by everyman's right (ym.fi). The Koli National Park area is governed by the park's rules.
- Please familiarise yourself with everyman's right and the Koli National Park rules before setting off on an excursion.
- The Herajärvi Trail is available when the ground is unfrozen. The amount of snow varies from year to year, but the trail is usually open from May until November. If you are planning a hike early in the spring or late in the autumn, you should check the snow situation at the Koli Nature Centre Ukko before setting off.
- Lighting campfires is forbidden if a forest fire warning or the grass fire warning is in effect. Check the current warnings (en.ilmatieteenlaitos.fi).
- This prohibition does not apply to cooking shelters or other fireplaces with a flue and a roof.
- It may not be possible to cross the River Herajoki during the spring and autumn floods, and the wading cable is unavailable in that situation. You can get round the wading cable section by using Herajoentie, the bridge and Vaaralahdentie. If you skip the wading cable and climbing onto Hirvivaara Hill and, after Vesivaara Hill, go along Herajoentie to the Rekilammentie crossroads, the length of the section to walk along the road is 3 km, and the hike is shortened by roughly one kilometre.
Mobile Phone Coverage
- Although Finland has a broad network for mobile phones, there are some areas in the trail without signal. There may also be some smaller spots where there is interference. If this happens try to climb to a higher place or go into an open area. It may be worth removing the SIM card from your phone and then trying again to make emergency call. Different phones also differ in their coverage.
- We recommend that you keep your mobile phone warm at all times and take along food and drink. Certain phone models do not work when the temperature falls below zero. You should therefore let someone know your planned route. To keep your mobile phone charged, bring along a spare power source, a spare battery or an old phone with a working battery.
Equipment and Safety
- Although the trail is well marked, you should take a map and a compass with you. The distance to the nearest houses and roads from anywhere on the trail is five kilometres at the most.
- The trail is challenging due to the cliffs, so hiking will take more time than usual.
- If you face an emergency on your hike, e.g. get lost, get injured or observe wildfire, call 112 and report an emergency. More information on how to act in an emergency.
- Make sure you pack a first-aid kit.

A fire can be also lit in fireplaces at wilderness and other huts. Always use extreme caution when handling fire. The one who lights a fire is always responsible for its safe use.
