If you're sitting around on a Saturday afternoon or a summer evening and wondering what's free to do in Oslo, I've got an idea for you. Totally random. Totally Norwegian.
Pay a visit to the Holmenkollen Troll!
Take the Number 1 Metro line up to the Holmenkollen stop. From there it's a bit of a walk uphill, but the way is well-marked. Even if you've visited the ski jump before, you may not have swung out to visit the troll. He sits in a cluster of pines facing the jump, and only when you get up close do you find he has a little friend, too.
"A troll am I. Big and tall. I sing in one of my songs. For I am big and tall. When you see me sitting at Gratishaugen, I measure almost 7 meters. Big and tall may sound dangerous, but that's not the case. I am a good troll. It is the famous Norwegian sculptor Nils Aas, who brought me here. I am made of concrete, and I guess I do look a lot like the trolls you'll find in the Norwegian folk tales collected by Asbjørnsen and Moe."
Wave goodbye to the troll and stroll down the road a bit to give your inner child another thrill at Himalaya Park . Several fun obstacles and playground-style installments on the low ropes course are available for your use and pleasure. A rope wall, a hideout, a balance beam, a swinging bridge. It's full of pulleys and ropes, and it's free! (At least, it was the last couple times we wandered through it.)
I suppose this is really meant for families with kids, but... I don't have a kid; I have a husband with an active inner child. (Which means I'm rarely bored in Oslo!) Enjoy!
