The Thermes might be one the best hidden treasures of the Greek Isles. Katrina and I love coming here to relax and heal whenever we’re on Kos Island. The sulfur rich salty waters, which many believe to be medicinal, have been especially soothing for my ascaris skin infection. The Thermes are a natural hot spring bubbling up into the Aegean Sea on Kos’ southern coast located on the eastern edge of the island about 12 kilometers (7.2 miles) south of Kos Town under majestic cliffs and a wonderfully spooky old building. The pool is large enough to accommodate at least 60 swimmers. Plenty of room to allow for cooler spots that you can float into when you need to dissipate some heat from the warmer waters that can range as high as 42o C (108 o F) – 50o C (122 o F). If you are planning a trip to the Greek Isles I highly recommend spending some time in Kos to take in the soothing waters of the Thermes, and while you’re there enjoy Kos’s other beautiful sites and delicious Greek Cuisine.
