Porphyry Island is a cool island located in Lake Superior, which is one of the Great Lakes in Canada. You can find it in the Thunder Bay District of Ontario. This island is the very last one in a line of islands that stretch southwest from the Black Bay Peninsula.
Porphyry Island is about 6 kilometers (4 miles) from Edward Island Provincial Park. It's also around 13 kilometers (8 miles) from Sleeping Giant Provincial Park. If you travel east, it's about 14 kilometers (9 miles) from Silver Islet, Ontario. The city of Thunder Bay is about 42 kilometers (26 miles) to the west.
