Hidden in the forest and just a stone’s throw from the lake, this cozy red kiosk is a welcome surprise for hungry hikers and cyclists. Coffee, waffles, ice cream or a warm cinnamon bun, everything tastes better after a few kilometers in the woods. Picnic tables nearby invite you to sit, relax, and soak in the peaceful surroundings.

Panoramic viewpoint over Nordmarka and the lakes below. From Mellomkollen, you get a wide-angle view stretching across forests, valleys, and water, especially striking in the golden light of early morning or late afternoon. A perfect spot to pause, breathe, and take it all in.

A peaceful clearing by the water’s edge, perfect for a lunch break or a slow coffee with a view. Surrounded by forest and framed by smooth rocks, this spot has a fire ring and a raw, natural charm. On a calm day, the lake turns into a mirror making it hard to leave.

A short but dramatic crossing above the roaring Helvetesfossen. Surrounded by dense forest and the sound of rushing water, it’s a spot well worth pausing at to soak in the raw energy of the place before continuing your ride or hike.

Tucked between tall pines and with roots underfoot, this quiet picnic spot offers a front-row seat to Øyungen’s calm waters. It's perfect for a lunch with a view, a break after hiking, or simply soaking up the peaceful forest atmosphere.

🌱💧A beautiful wetland area surrounding various ponds. Caution: Even in spring, there may still be snow there, as it's much colder in the hollows. Plank paths lead through some of the area, but they can be difficult to find in the snow. So, it's easy to break through the snow and plunge straight into the cool water. 🥶
