I absolutely love Bagsværd Sø! it’s 6.8 km around, so it’s a nice big lake. It is really nice to go for a walk around the lake. It’s a gorgeous lake, and perfect to take your dog around. The water quality in the lake is not suited for swimming as the lake still receives spillover from three outlets from the public sewer system. It is however possible to rent canoes, kayaks, rowboats and sailboats. Which is super fun, and highly recommended! :)
