To get to this amazing cliff it takes about an hour in total. 25 minutes drive from Tórshavn to Skopun, Sandoy the village where the ferry used to come before the tunnel came to be. The rest is hiking. So  once you arrive in Skopun you need to drive into the village and take a narrow road. Basically until you get to the end of the road.  You walk a bit up the hill and you will see a sign showing the path to the cliff. The path is well marked with Wooden sticks called priests. Just follow them and you will get to the amazing view of Líraberg cliff. It might take you a bit longer depending on your pace, but this hike is an easy one overall.

When I was there last time it took me about 3 hours, but I stopped taking pictures, flying my drone and eating a snack. I could easily make it back and forward in 2 hours.

PS - This is a great spot for sunset.
