From the round-about in Os centre (Osøyro) drive road 552 towards Bergen for 2.7 km, until you get to the round-about where roads E39 and 552 meet. Turn right, driving towards Bergen, and immediately turn right again onto the street called "Tøsdalsveien". There is an UnoX petrol station at the other side of the road (per 2009). Continue 1.0 km along this street, and follow the right leg when you get to the fork. Drive another 300 metres until you have a car park on your left hand side. Park here.
Start walking by following the narrow forest road that starts from the car park; you will see signs for "Møsnuken" here. After approximately 170 metres you get to a ladder stile, which you climb, and then cross the small bridge. Follow the path uphill for 140 metres measured from the stile, until you get to a second ladder stile. Climb this stile, and immediately turn left. Continue across the third ladder stile and continue on the path on the other side of the stile.
Follow the clearly visible path all the way to the summit. Note that the first time you see the summit properly is when you get to the first registration point (a post box), just below Tyssdalsfjellet. The summit of Møsnuken is marked by a sign, and there is a registration book also here.
The descent is best done by reversing the ascent route.
I was spending three days at our factory in Hagavik south of Bergen, and since we finished work quite early this Tuesday afternoon it was sufficient time to take on one of the highest Os mountains. Unfortunately it was cloudy and to a small extent a bit foggy, which in a blunt way summarizes my hiking summer of 2009. And, of course, as I later at night found out, the weather back home was gorgeous this afternoon.
I had been told by a colleague living in the area that I would probably get to the summit in less than one hour. I was a bit sceptical about this, but knew that if it took me longer I would still be fine in terms of day light. After only 18 minutes I was thinking I had to be close to the summit, and for the next 25 minutes I thought on several occasions that "I'm must now be only a few minutes away from the summit". On one occasion I even climbed onto a small peak, assuming this was the summit, only to find out that this was Tyssdalsfjellet and that the summit of Møsnuken was still a fair distance away. When I eventually got to the summit I wasn't sure I had it this time before I was standing at the summit and could see that this was indeed the highest of the many small peaks on the large summit plateau. A sign on the summit saying "Møsnuken" also helped in confirming this.
Having done a lot of running on my way to the summit I was soaking wet from sweating, so I didn't stay very long on the summit. Instead I started by run back down to the car, where I arrived without having seen a single person throughout my close to two hours long hike.
