The Helgafell is the "home mountain" of the city Hafnarfjörður and easy to reach by car. The starting point of the hike is at the water reserve near Kaldársel.

There are several ways to reach the summit. Coming from the parking lot, it's worth taking the more direct, more exciting route and taking one of the other descent options.

The landmark of the Valahnú course was also recreated as a sculpture and is located in front of the supermarket "Fjarðarkaup" in the city of Hafnarfjörður.
