Kesämaa is a water and activity park on the shore of Lake Saimaa in the Punkaharju esker landscape, about 30 km from Savonlinna. Its headline feature is a water slide over 150 metres long, alongside several pools sized for different ages. Other activities include a pedal-car park, bouncy and climbing spots, an artificial pond with rowboats and bumper boats, and the SmartUs interactive game court that combines physical play with technology. The grounds also have saunas, a restaurant, a grill shelter and the adjoining Punkaharju ridge nature reserve. Nearby there is accommodation from holiday apartments to camping cabins, plus tent and caravan sites, making it a base for a longer summer stay.
