The hike up.. close to 3000 vertical feet. actually the building on the top is part of a lift that goes up to the top inside the mountain. i think its a old military instalment. its open to public a few weekends late spring. took a couple of years ago. theres actually also big barrels of cognac stored in the top building ! apparently its labeled and sold as Gaustatoppen cognac.. theres also a tourist cabin to the left of the tower. parts of it is not locked in winter.
not sure how to delete double posted pics..
