Lahti Harbour is the go-to hangout spot for locals in Lahti, especially during the summer. With its lively atmosphere, waterfront restaurants, and cafés, it's the perfect place to chill by the water. Don't miss out on Sibelius Hall, where you can catch concerts and cultural events. And if you're feeling adventurous, hop on a cruise ship for a scenic journey around Lake Vesijärvi. It's basically the living room of Lahti residents!
