Berlin is a vast city with not one, but several centres that come in their distinct and varied flavours of cool. The fastest and most time efficient way to hit all the main attractions is to get on one of those hop-on hop-off buses. You can get a 24- or 48-hour ticket, as well as an option to upgrade to a river cruise boat. Buses run every 10–15 minutes. Of course, you get audio commentary in multiple languages, plus a kids' channel.

As evening falls, the daylight in Ghent does not simply make way for the streetlights. There is light art to enjoy as well. Streets, squares and buildings are covered in an artistic light display. It is almost as though the city were getting dressed up for the theatre. The effect is awe-inspiring. Discover Ghent Alight and immerse yourself in this de-light-ful evening experience! The Ghent Light Plan was first designed in 1998. The idea was to provide sustainable lighting for the city without wasting energy. But at the same time, it has transformed the centre of Ghent into a magical nocturnal landscape of light and shadow. Architectural accents, streets, monuments and squares are lit up to display them at their best. Ghent is a leading light in combining environmentally conscious lighting with beauty. Let the play of atmospheric lights spark your imagination. Rediscover the city by night in a whole different way. The city has received many prizes and international acclaim for its pioneering role in integrated city lighting and illumination. Would you like a sparkling tour of Ghent’s most beautiful illuminated buildings and squares? Follow the light walk and discover it for yourself! Start at the Kouter for a walk of approximately three miles. The walk takes you past all the highlights of the Ghent illuminations. You will need about two hours to complete the entire walk. It’s best not to start too late, because at the stroke of midnight, the atmospheric lighting is replaced by ordinary streetlights. Plan your walk with one of the guides. Or explore for yourself!

In Skäftekärr, close to Böda in northern Öland, lies an Iron Age village with around 20 well-preserved stone house foundations spread across 10 farms dating from 300–700 AD. At the heart of the Iron Age village are the remains of a chieftain's estate, comprising four house foundations. Adjacent to this historic site, the "new Iron Age landscape" includes a reconstructed version of one of these typical houses and the charred remains of an earlier reconstruction. The park is also home to an impressive collection of approximately 140 different species of trees and shrubs, forming an arboretum. An eco-park center with information about the Böda Eco-park is available on-site, along with Skäftekärr café, hotel, and conference, housed in the majestic main building. For the little ones, a popular obstacle course adds to the day's adventure.
