With "lakefront" in the trail's name you know this bike path is on some prime real estate — and what's more scenic than rolling along the edge of Lake Michigan? With the shoreline on one side and a view of the city skyline behind you, Chicago's Lakefront Bike Path is the picturesque urban biker's dream. The 18.5 asphalt miles between Rogers Park and the South Shore Cultural Center includes the Shedd Aquarium and the Navy Pier where you can rent bikes as well as check out Pier Park's Ferris wheel and miniature golf course. But if your bike rides are strictly for fitness, you can easily turn the bike ride into a whole day of physical activities thanks to the volleyball courts, playgrounds, baseball diamonds, tennis courts and soccer fields found along the path.
