The shore has an irregular shape, which is characterised by many bays along its shoreline, and long narrow peninsulas, which deeply cut through the lake.

The largest of them is Różany Ostrów also known as Wyspa Róż at 54 ha (130 acres) which is linked to the mainland by a bridge.

Some roots of the trees are visible due to waves eroding their soil, creating a separate characteristic to the part of the lake.

There is a large amount of swamp vegetation, including the following species found in the lake: bugleweed, bittersweet, water mint, yellow water-lily, and Canadian waterweed.

There are different types of plants in that part than elsewhere: there are blueberries, blackberries and moss, and in the autumn mushrooms grow.
