Ringkollen is a beautiful area only a one hour drive from Oslo city centre. Here you can go biking, hiking, skiing and crosscoountry skiing. A beautiful nature area, not crowded, away from all the noise and fuzz. But be aware to bring your own gear, and we suggest you are known to outdoor living before going alone into the forrest. Good hiking shoes and good clothes are mandatory!
