View over Bromme Lillesø
A quiet lake with exceptionally clear water, hidden in the moraine landscape at Bromme north of Sorø. The viewpoint offers first-class birdwatching — Eurasian bittern and hobby are among the regular visitors.

A Hidden Lake in the Hills near Bromme
Bromme Lillesø sits tucked into a rolling moraine landscape northeast of Sorø, surrounded by open farmland and scattered scrub. The lake is small — you could almost skip a stone across it — but the water quality is remarkably good. Clear springs feed the lake and keep the temperature cool even in midsummer. From the viewpoint on the northern shore, you get an unobstructed view across the water and the gently undulating terrain beyond. On still mornings the sky reflects so sharply on the surface that it becomes hard to tell where water ends and air begins.
Birdwatching at Its Best
Bromme Lillesø is one of those places in Sorø Municipality where you can still encounter the Eurasian bittern. The shy heron hides in the reed beds along the lake's southern shore, and its deep, booming call carries through the early morning air from April to June. The hobby — one of Denmark's most elegant birds of prey — hunts insects over the water surface in summer. Its swift, swallow-like flight is unmistakable as it swoops low over the reeds. Greylag geese, coots and great crested grebes are permanent residents, and during migration season wading birds regularly appear along the shallow banks.
A Landscape Shaped by Ice
The terrain around Bromme Lillesø was formed during the last Ice Age, when retreating glaciers left behind a mosaic of hills, hollows and dead-ice holes. The lake itself is precisely such a dead-ice hole — a depression created when a buried block of ice slowly melted away. The surrounding area is dominated by intensive agriculture, but the lakeshore itself has preserved a strip of undisturbed nature with willow thickets, reed beds and wildflowers. In spring the banks light up with marsh marigolds and cotton grass, and in summer dragonflies hum over the still water.
Peace and Contemplation
Bromme Lillesø is not a place with facilities and activities — it is a place you seek out for the silence and the view. Bring a pair of binoculars and sit on the bench at the viewpoint. From here you can follow the comings and goings of the birds without disturbing them. The area is especially beautiful in the early morning and towards evening, when the light falls at an angle across the water and the colours shift. It is the kind of place you come to for a deep breath and a slower pace.
Getting There
Bromme Lillesø lies near Anagervej in Bromme, just a few kilometres northeast of Sorø town. The area is not signposted as a formal destination, but a gravel track leads down towards the lake and there is room to park along the road. Cyclists on the route between Sorø and Ringsted will find the lake a natural rest stop — it lies only a short distance from the main road yet feels like an entirely different world.
Explore the Wider Area
From Bromme Lillesø it is not far to Bromme Plantage, where a shelter site offers primitive overnight stays in conifer forest. The town of Sorø with the Academy Garden, the monastery and the three lakes is just a ten-minute drive to the southwest. The entire Sorø area brims with nature trails, cultural history and outdoor opportunities — find inspiration for your next outing at destinationsjaelland.dk.
