Blå lagunen, Munsön

Blå lagunen (The Blue Lagoon), located on the picturesque island of Munsön in the Ekerö municipality, is one of the most remarkable swimming spots in the greater Stockholm area. What was once an active gravel pit has transformed over the years into a stunning artificial lake. As groundwater seeped in, it filled the massive crater with crystal-clear water that glows with a vivid, inviting turquoise hue, a color rarely seen in typical Swedish lakes. This mesmerizing visual effect is created by the light reflecting off the light-colored sand and mineral-rich bottom.

The environment around Blå lagunen is rustic and natural, characterized by steep sandy banks, gravel slopes, and a surrounding border of classic Swedish pine forest. The striking contrast between the bright, almost tropical-looking water and the Nordic landscape creates a truly unique atmosphere. Visitors flock here on warm summer days to sunbathe on the sandy stretches, enjoy picnics, and take refreshing dips in the exceptionally clear water.

Despite its popularity, the area retains a somewhat wild and undeveloped charm. You won't find luxurious beach clubs or paved promenades here; instead, the focus is purely on the raw beauty of the landscape and the fantastic swimming experience. It serves as a perfect day-trip destination for city dwellers wanting to escape the urban heat and immerse themselves in an exotic-feeling oasis without ever leaving Sweden.

ParkingThere is a dedicated, paid parking area near the beach, but it gets full very early on hot summer days.

EntranceThe beach itself is completely free to enter, but parking requires a fee.

LifeguardThere are no active lifeguards on duty, so swimming is entirely at your own risk.
