This small bridge is always interesting to look at because it blends in well with the surroundings. The two elements on the left and right are made of solid stone, while the bridge itself is constructed of wood.

Cosy cabin café tucked into the forest, a perfect stop for a coffee or waffle after a walk around the lake.

Nestled in the forest above Nøklevann, Sarabråten was once the summer estate of Christiania’s 19th-century elite, hosted by timber baron Thorvald Meyer. Today, only a few ruins remain, but the place still carries a quiet grandeur, perfect for a reflective pause in the woods.

A calm and scenic place to pause on the shore of Nøklevann. With flat rocks, benches, and space to relax, it's ideal for lunch with a view.

Nice as a stage stop. A nice little stone staircase down into the water, which is very decorative. Here there is also runoff from the Ulsrudvannet in a stream under the road. If you are observant enough, you will see that there are a lot of fugitive boxes hung up in the trees around here.
