Ireland has 29 warm springs many of which were important to religious ceremony in pre Christian Ireland. The only currently operating warm spring in Ireland is in Lisdoonvarna. The spa is open from June to October with high season in September when the singles descend on the town for the world’s largest matchmaking festival.
There seems to be no official definition of “warm spring,” but can be loosely defined as a spring with the water temperature between 20 °C (68 °F) and 50 °C (122 °F). In all likelihood they are much less popular than hot springs because body temperature is 33.2–38.2 °C (92–101 °F). However, like hot springs, warm springs are often full of minerals and can be heated to a more comfortable temperature.
Happy St. Patrick’s Day
