Varkaus

The highway number 5 goes right through Varkaus and since it's a pretty small town, all the hh-spots are easy to reach. If you're coming from north-east (road #23) and being dropped off at the eastern part of the town, you might have to walk a couple of kilometers through the city to reach either the other end of the road #23 or the highway number 5. Just follow the street called Taipaleentie or the "Mikkeli/Jyväskylä/Kuopio"-signs. And the other way round: coming from south/west/north heading to east and being dropped off by the highway #5, walk through the city following the "Joensuu"-signs to reach the road #23.

There are 2 gas stations in the crossing of highway #5 and #23, where you can ask the drivers. These are pretty good places to ask rides to all directions. You can also try hitchiking on the ramps.

If you're going west towards Jyväskylä and Tampere, you could also try hitchhiking in a bus stop next to the smaller gas station.

Heading to east/north-east? When you're on the street Taipaleentie, walk past the sawmill and you can start hitchiking on the roadside right after the first crossing to right (there might even be a bus stop if I remember right?).
