Although they charge to get on the Fisherman's Bastion, you can enjoy the beautiful structure and fantastic view without paying the 700 HUF.
The view is Great! You can go up by gondel, by elevator, by stairs or by electric stairs.
A trip up to Fisherman's Bastion in Buda offers arguably the best views in the whole city. This massive structure of white stone is joy to walk around and explore. Here you'll look out over the Danube, the stunning Parliament building and all of Pest stretching out into the distance.
One of the first places you should visit when you are in Budapest so that you can get a great view of the city. The walls are not old, but were rebuilt in a great "old castle" look. It is quite a hike up the hill, but you can also take a taxi or the funicular if you are not up to the physical activity.
day or night the views are spectacular. get some snacks and some wine or beer and enjoy the view
