5km/3mi beyond the Glarus exit the N3 highway comes to a parking place and just beyond this, on the left, is the Walensee restaurant. 1km/0.5mi further on is an exit (cars only) to the village of Mühlehorn (426 m/1,398ft), at the inflow of the Merenbach into the Walensee. The road continues along above the lake, traversing two tunnels, and past
the Mühlehorn/Kerenzerberg junction where the road from the Kerenzerberg comes in. The highway now begins to climb a little. In another 1.5km/1mi it comes to the village of Murg.
