Punavuori was once known as a run-down area outside of the city center, but the neighborhood underwent something of a transformation in the second half of the 20th-century and is now one of Helsinki's coolest areas. For a great introduction to the area, wander down the quirky Iso Roobertinkatu and check out some of its bars, boutiques, and restaurants. From sushi in a living room restaurant to hot mojitos in a Mexican bar, Punavuori has got you covered on the quirky eating and drinking front. Turn down a side street to discover homemade candy stores, green spaces and – in summer – the eclectic Hietalahti Flea Market. When the sun is shining, there's no more enjoyable way to mix with the locals than by eating a picnic in Punavuori's Sunbrychoffin park and drinking 'pussikalja' – beer in a bag. When the weather gets a bit colder – and it does get very cold indeed – forget the picnic and join in with a spot of sledding instead. The park's crater-like shape is perfect for some snow-fuelled fun, and yes – you should take your 'pussikalja' with you then, too.
