Downtown Port Austin is an extremely bike friendly area. You can get almost anywhere in just a few minutes with a leisurely bike ride. 

If you're looking for something to get your heart pumping a little faster, M25 offers a wide shoulder/bike lane with stunning views of Lake Huron that takes you around the entire Thumb.

If you find yourself in Port Austin without a bike, drop by Port Austin Kayak and they will have several styles for you to rent. 

Each year, the Tour di Lago bike tour begins and ends in Port Austin and provides multiple routs with distances for every skill level of rider.
