This is a beautiful Culture Centre (Arts Centre? Not sure of the direct translation) just outside…read morethe centre of Oslo. Even if you're traveling with small kids or fussy "meh, not really into art"-types, Henie Onstad is worth a visit. It's a beautiful site, and the drive from Oslo (we took a car, but local public transportation makes it accessible via bus) takes you along the water. Henie Onstad has an indoor structure with a gift shop and whatever exhibitions are on at the time (note: there is a cost for admission). There is also a lovely cafe serving a variety of options. When we were there most were opting for glasses of chilled wine on a balmy July afternoon, with outdoor seating overlooking the water. I can think of few locations better. The real star of the show, though, is the outside of Henie Onstad. It serves as a great public park space where kids and dogs and local Norwegians sit, and picnic, and sun themselves on the rocks. Because the site is on a point there are both public and more private spots to relax; in the case of the former there are two main swimming areas with great jumping spots to launch off of into the water. Spotted around the grounds are also many sculptures; some abstract, some less so, and it's a great time just walking around trying to pick out all of the art. No wifi, but free parking. Recommended visit. Yelp note: it seems like a destination spot for a lot of locals on a sunny day. Looking out over the marina remember to bring your bathing suit and maybe even a few sausages...the man next to us had a portable grill so you could get lucky and score a cheap meal AND a great swimming hole surrounded by art at no-cost (DREAMDATE).
