If you need a dose of nature while in Helsinki, a great option is to go for a walk or jogging in Keskuspuisto, Central Park. It's easy to reach by tram or bus. I recommend going beyond Ruskeasuo if you yearn for more forested landscapes. The photo is taken in December near Ruskeasuo.
Orion is one of the nicest cinemas in Helsinki. It is run by National Audiovisual Archive so they are showing a great variety of films from art house to modern classics and everything in between. Last time I went to see Hitchcock’s Vertigo.
Tramline 3B will take you almost anywhere in downtown Helsinki. If you want to get an overall picture of the city centre and its surroundings taking a tour on this tramline is a good way to do so. 3B is the only tramline that operates late at night so if you’re visiting Helsinki there’s a great chance that you’ll end up using it.
This place is known for the personal owner, Kostas, from Greece and they say the coffee is great, but I don't drink coffee. I come here for the Hot Chocolate, the best in town.
