Tobermory is located on the northern tip of the "Bruce Peninsula". If you had started to hike the Bruce trail in the Niagara Peninsula you have completed this challenge here.
My first major trip in Canada was with a German colleague. We went to Manitoulin Island in Lake Huron. We used the yellow truck which you see in the next picture. We made the decision only a day earlier and did not book a reservations for the ferry. So we had to wait over night for the next tour of the "Chi-Cheemaun". I enjoyed this trip very much.
Unfortunately, we could only stay for an extended long weekend and were not able to see most of the attractions which Tobermory offers.

Tobermory and its surroundings are worth to spend the whole vacations there. So many attractions and so much to do.
If we learn scuba diving we would join a guided tour to visit some of the shipwrecks.
Elizabeth, my wife, could finally improve her skills in sea kayaking. I had a wooden kayak as a teenager which required good skills - the new plastic kayaks are much heavier and there is no comparison to my old one. However, the new generation seems to be much safer for a not so experienced paddlers.

Visit "Flowerpot Island" and visit the remaining "flowerpots" - a rock formation created over many, many years by the waves of the lake.

In the meantime I learned that the National Parks and the Provincial Parks are the best way to enjoy nature. The "Bruce Peninsula National Park" will not be an exception. We will not camp there but use the normally offered day passes.
