The Cheonggyecheon was originally a creek that flowed through downtown Seoul -- in the wake of rapid post-war economic development, it was buried under concrete to facilitate urban expansion. Today, however, the over 10 km-long creek and its banks have been uncovered and remodelled into an exciting recreational area for locals and tourists, with clean water and natural habitats bordering on residential and office buildings.

The Kelonia turtle centre is home to dozens of marine turtles, some of which visitors can come in direct contact with. Apart from providing unique entertainment to visitors, the centre contributes to research on migration patterns and turtle populations, aimed at preserving the species.

In the middle of the Øresund strait, right between Sweden and Denmark, lies the idyllic island of Ven. The astronomer Tycho Brahe was gifted the whole island by King Fredrik II after he discovered a new star in the Cassiopeia constellation. Here he constructed one of the most interesting buildings of the time: the Uraniborg castle, a subterranean observatory called Stjerneborg and a renaissance garden. The New Church of Ven has now been turned into a museum, the garden has been renovated, and in the observatory you can watch a light and sound show. The light in Ven is said to have a unique quality, which has attracted many an artist and ceramist to the island. Take a tour among the studios and workshops, and meet with sculptors and silversmiths along the way. Ven is a small island, and the best way to get around is by bike, which you can easily rent when you get off the ferry.
