Oslo Swimmers Embrace Outdoor Pools and Rock Formations for Lap Training

Oslo Kommune opened the seasonal lap lanes at Frognerbadet on 15 June this year, drawing 1,200 daily visitors in the first week alone for 50-metre swims in the 25-metre outdoor pool on Kirkeveien.

Public health data released by the city in late June shows a 22 per cent increase in outdoor swimming permits compared with the same period in 2025, reflecting both warmer fjord waters and expanded access to maintained facilities. Residents cite lower costs than indoor gyms and the chance to combine exercise with daylight hours that stretch past 10pm in July.

Two Oslo sites drawing regular lap swimmers

Frognerbadet maintains four dedicated lap lanes from 7am to 9am on weekdays, with entry at 85 kroner for adults and 45 kroner for those under 18. The adjacent park provides changing rooms and a kiosk selling coffee and protein bars. Further west, the rock pools at Huk on Bygdøy peninsula offer natural 30-metre straightaways between flat granite slabs, marked by buoys installed by the local swimming club Bækkelagets SK each June. Swimmers reach the site via the number 30 bus to the final stop, then a five-minute walk along the marked path.

Both locations sit within 20 minutes of central Oslo by public transport, avoiding the need for cars during peak tourist weeks. City maps updated in May list water-quality readings taken every Tuesday, with results posted on the Oslo Bymiljøetaten website by 2pm the same day.

Practical steps before heading out

Check the daily schedule on oslo.kommune.no before 6pm the prior evening, as lane availability can shift for school groups. Bring a silicone cap and goggles rated for salt water if using the Huk rocks, where currents remain mild but visibility drops after rainfall. Local shops on Bogstadveien stock day passes and towel rentals for 30 kroner if travellers arrive without gear. Early morning visits avoid the midday crowds that peak between 11am and 2pm at both sites.

Swimmers report completing 20 to 40 lengths comfortably in the maintained pool and similar distances between the marked rock points before the tide shifts. Those new to open-water routes can join the free Saturday orientation swims run by Bækkelagets SK, which begin at 8am from the Huk bus stop through the end of August.
