Just beautiful on a summers day - there are lots of walking tracks, big lawns to throw a frisbee, various cafés, a nursery, butterfly house, etc. Worth spending a full day checking it out.
You must explore the whole area! Start tour walk from Karolinska sjukhuset's entrance up till the butterfly house. A walk by the water... A very beautiful place to be in summer!
One of many parks in Stockholm, but probably the nicest. Take one hour to walk through this beautiful park located close to the central part of Stockholm. Stay look at the views and enjoy.
