I review this as a great place for a picnic with the tables and everything. A gorgeous view to the fjord and a peaceful, green environment. Pack your lunch or buy it from the Coop next door (marked as post office in the map). If you are a customer you can park by Coop for free for 1h.
Greenery everywhere with a small play area for kids. This is the best view for a 360 degree view of Flåm. We visited in summer. If you are lucky, you can also see the big cruise parked nearby from this place. Beautiful Village of Flåm where everything is at walking distance.
