The water is usually clean and safe to drink in the whole area, however the quality of the water cannot be monitored, so the use of natural water is at your own risk. During warm weather water should be boiled before drinking.
There is a household water well by Lake Sompiojärvi. The quality of the water is monitored.
On the Ruijanpolku Trail you must take care of waste disposal yourself. Biodegradable waste should be placed in a toilet or composter, and small amounts of clean paper and cardboard can be used as kindling in a campfire. Take all other waste from the hike with you.
There is a waste bin point by Lake Sompiojärvi. There are municipal recycling points in Kiilopää and Laanila.
Making a fire is only allowed at the maintained campfire sites along the Ruijanpolku Trail. There, you will find firewood cut into one-metre logs. There is always a saw and an axe in the woodshed for chopping the logs.
The campfire sites are located on the shores of Lake Sompiojärvi, at the foot of Terävä-Nattanen Fell and by the Kaptukaislammet Ponds. There are lean-to shelters by Sivakkaoja and Kopsusjärventie Road (about 500 m west of Ruijanpolku), where you can make a campfire.
