Best Time to Visit Kythnos: Thermal Springs and Double Beaches

Kythnos is famous for the iconic Kolona beach · a sandbar connecting the island to an islet, creating a sea on both sides. It is also a major hub for yachting due to its proximity to Athens.

The Sailing Schedule

Kythnos is typically the first or last stop for sailboats chartering out of Athens (Alimos/Lavrio). Consequently, the port of Merichas and the bay of Kolona are incredibly busy on Friday nights and Sunday mornings. Visiting mid-week in June or September ensures a much quieter experience.

Thermal Springs

The village of Loutra is home to natural thermal springs that flow into the sea. This makes Kythnos a viable destination even in the cooler months of April and October, where a hot soak in the sea is particularly enjoyable.

Why Visit Kythnos?
