There is not on the go in Tobermory for nightlight in the off season but there are opportunities I guess. In Ontario the liquor stores are referred to as LCBO.
You will find one of these in Tobermory and there is one in Wiarton as well at 415 William Street. There are some more as well in Bruce Country and the web site can help you locate them all.
Check the store hours because they are not always open late.
Since the peninsula extends northward, with Georgian bay to the east and Lake Huron to the west, you must be on the west side to view one of Lake Huron's spectacular sunsets.
We drove to Red Bay and sat on the long pier to await sunset....and we weren't alone. Many people gather at the beaches in the evening for this free nighttime show.
