Pelee Island sits in Lake Erie, low, warm, and separated from mainland Ontario by a ferry ride. It is the southernmost inhabited place in Canada, and that odd latitude matters: vineyards grow here, Carolinian species hang on, and migrating birds and monarch butterflies use the island as a stopover.
The best way to see Pelee is by bicycle. The roads are flat, distances are modest, and the island rewards slow movement: beaches, fields, windbreaks, limestone alvars, and the long points of Fish Point and Lighthouse Point. The Heritage Centre adds the human layer: Indigenous presence, settlement, shipwrecks, farming, and wine.
Pelee is worth the ferry if you want quiet island time rather than a busy beach town. Check sailing times carefully; the water decides more than the map suggests.
