The Korpilahti harbour is located near the centre of Korpilahti. It was established more than 100 years ago, at a time when steamboats began to sail Lake Päijänne. In addition to harbour and restaurant services, the area offers an art gallery, a craft shop and a summer theatre.
The Korpilahti harbour is a refreshing stop for people travelling by water and by land. In 2006, the Korpilahti harbour was selected as guest marina of the year. In the spring of 2012, it received an honourable mention in the annual Finnish Sailing and Boating Federation vote for guest marina of the year. In 2019 the Korpilahti harbour was again awarded as the best guest marina! Its service and restaurant building offers a wide variety of services for boaters and other visitors.
