Am Stadtwaldsee Nature Reserve
About

Am Stadtwaldsee Nature Reserve—also known as the Unisee—is Bremen’s largest quarry lake and a beloved green retreat near the University of Bremen. Created in the 1970s during motorway construction, the lake spans 28 hectares and reaches depths of up to 16.5 meters. Fed by groundwater, its slightly saline waters are known for their clarity and quality, making it a popular spot for swimming, sunbathing, and water sports. The reserve features sandy beaches, a nudist area, and a loop trail ideal for walking and jogging. On the northeastern shore lies the “Uni-Wildnis,” a rewilded zone that supports diverse flora and fauna, contributing to Bremen’s ecological network. The area is also used for educational and recreational purposes, with supervised swimming zones and a playground for families. Located in the Horn-Lehe district, Am Stadtwaldsee offers a rare blend of urban accessibility and natural tranquility, making it a vital part of Bremen’s outdoor culture and environmental stewardship.
