Fjallið Millum Botnar is a mountain close to a famous mountain called Sornfelli. To get there you need to park your car in the parking lot of Mount Sornfelli. The hike takes about 45 minutes to an hour to get to the top. I do not recommend doing this hike by yourself as the last part is a bit dangerous and you will need to know where to walk. There is no clear path. 
 
Once you get to the view point you will see a valley with a lake and on a clear day you will also see all the south islands.
