Despite being the country's largest lake, Lake Saimaa is still relatively unknown to people outside Scandinavia. A haven for paddleboarding, canoeing and kayaking thanks to its string of quiet waterways, the lake is pockmarked with over 14,000 miniature islands where you can anchor up and explore. Tired from a day of water-fuelled activities? Head to Hotel & Spa Resort Järvisydän's Lake Spa for a traditional smoke sauna, then follow this with a quick cooling plunge into the lake.
