This almost 11 km long trail is one of the finest trails I have every ridden in the Oslo area. It’s got everything you want from a trail. Steep uphill and downhill – both making your heart beat faster, though for entirely different reasons. Other areas consist of open pine forest areas with few technical difficulties and lots of light and space, and which of course are ready for some fast riding. You also got small jumps due to blocks of Grorud granite lying around. Other areas you’ll come by are made up of dense spruce forests, (maybe) making you see elves and nymphs popping up behind rocks and roots. Lillomarka is scattered with paths, and if you want to do variants of this trail that is not a problem. Just don’t ride to fast if you’re out when everyone else are. However, if you do this trail early in the morning you’ll probably have most of the paths for yourself.
If you come by car you can park it at the parking lot close to the gas station at Grorud. The blue marked path start at Romsåsveien. However, you should skip this part and just take left up Ravnkollbakken and find the blue marked path from here. The path up to the top of Røverkollen is not technically difficult, but it’s quite steep and you’ll probably have to push your bike on some parts of it. There is a plateau there where you can get a really nice overview of Groruddalen. If it is beautiful or not is open for discussion. However, you can see all the way down to the center of Oslo. At the top you have built up a lot of potential energy. All this energy has to be released on the way down to Romstjern. So get ready for some fast and furious action.
When you come down to Romstjern just take left on the gravel road, and then right after about one hundred meters. The path now goes through a rather tight spruce forest. Some parts of it are quite technical. That’s just fun of course. After a little while and passing some cabins you’ll arrive at Lilloseter. If you want to buy stuff, be sure to bring cash. Last time they did not accept cards.
When leaving Lilloseter you’ll have to cycle parallel with the gravel road for a couple of hundred meters before you take left down the blue marked path. Now – get ready for one of the finest areas of this trip. The keywords are: fast and fun action. At the end you’ll arrive at the gravel road close to Breisjøen. Here you take left and follow the road before you take right into the blue marked path again. This stretch is at the beginning quite difficult and sometimes impossible to cycle. However, after a while you’re on some really nice doable tracks again. There are plenty of different paths you can choose to get down to Grorud. The one I chose was excellent!
