You most likely didn't come to Oslo to go to the beach. Even if you did, you'll find that you often have to swim from a rocky shore. Sun-loving Oslovians, desperate to absorb whatever sun they get on a summer day, often take to whatever remotely resembles a beach. Their few short weeks of summer last until around mid-August, when snow flurries start appearing in the Oslo sky.
Our favorite beach, and the most easily accessible from the center of Oslo, is Huk, on Bygdøy peninsula. To reach Huk, take bus no. 30 A -- marked BYGDØY -- to its final stop. Should you arrive by boat on Bygdøy, follow the signs along Juk Aveny to the beach. Our recommendation is to go over for the day; view the Viking Ship museum, the Folk Museum, and other attractions in the morning; then head for the beach -- preferably with the makings of a picnic -- for the early afternoon. In case there are any prudes in your party, be duly warned: Half of the beach is reserved for nudists. The nude beach is on the northwestern side. That same warning should go for all beaches in Norway; along with other Scandinavians, Oslovians like to strip down for the beach.
Once you get here, don't expect a traditional Hawaiian beach. The beach is mostly grass lawns and some smooth rocks that you can lie on to sun yourself like a lizard. If the beach at Huk is overcrowded, as it's likely to be on a summer day, take a 10-minute walk through the forest a bit north of where the bus stops. This leads to the more secluded beach at Paradisbukta.
These beaches are our favorites mainly because of their proximity to the center, not because they are great sandy strips. But our secret reason to go there is to people-watch. After a day at the beach, you'll soon agree with a common assessment: The people of Norway are among the handsomest and healthiest-looking in the world.
Our second-favorite beach is at Hovedøya, on the southwestern shore of the rocky island of Hovedøya. To get here, board boats 92 or 93 leaving from the pier at Oslo called Vippetangen. From late May to mid-August, these boats depart daily from around six in the morning until midnight.
This is the closest island to the mainland, and it's wildly popular in summer, as ideal for a picnic as it is for walks. The island is riddled with walking paths, most of which lead to the ruins of a 12th-century Cistercian monastery. Our main reason for liking this beach is its fun-loving atmosphere. It's a wonderful break from too much museum-hopping, and it'll give you a good chance to meet with the English-speaking Oslovians (whose initially icy reserve can melt quickly).
You can also reach a number of beaches on the east side of the fjord by taking bus no. 75 B from Jernbanetorget in East Oslo. Buses leave about every hour on weekends. It's a 12-minute ride to Ulvøya, the closest beach to the fjord and one of the best and safest for children. Nudists prefer a section here called Standskogen.
