What October feels like
Color peaks in the first half while the island quietly starts shutting down — hotels and shops close by stages through the month and the last ferries run at the end of it. This is also the wettest month of the year, so bring proper rain gear and check what is still open before you commit.
Rain arrives about 9 days of the month, so keep one flexible day in your plans. about 12 nights dip below freezing.
Can you swim?
The lake runs about 56° — frigid — locals in wetsuits only.
