Singö runt is the trail around Singö. It is a mix of single track, gravel roads and some tarmac. The trail goes through the beautiful nature on the island of Singö. 

The trail is mostly well marked, except for a shorter passage furthest north.

There is not much about the route online, but here is one example of where the trail is described: https://svalla.se/aktivitet/vandring/singo
