This hike doesn't have a super clear path to follow, at least not when you gain some elevation. I want to remember that it was a bit hard to find a good parking spot so we stopped here: goo.gl/maps/85qeNzEbYJjXzMg49 and then biked down the road a bit to a small road that took us to Tverrelva. But you should be able to navigate to Tverrelva pretty easy directly from the parking spot over Brentberget/Brentbergan. Hope this helps.
