[1] During the Bronze and Iron Ages, the Upper and Lower Rudasjöarna were connected and were part of a navigable watercourse that continued through Drevviken to Kalvfjärden and the Baltic Sea.

Through the land uplift , the contact was lost, but remnants of such connection and settlement are preserved at Övre Rudasjön, where the ancient castle Ruda skans probably dates from the Bronze Age.

The green area is also the starting point for several exercise tracks, among them is the 1.7 and 2.3-kilometer long Maxingeslingan, which stretches around Nedre Rudan.

The loop is an accessibility-adapted exercise track that has a hardened, smooth surface which makes it accessible for, say, a wheelchair, permobile, or pram.

On the western side of the lake, the Maxingeslingan runs close to the water, partly on footbridges.

The catchment area has 5.87 square kilometers of water surface, which gives it a lake percentage of 11.9 percent.
