Cardinal Greenway - Muncie Section Worth the 3 1/2 hour bike ride from Marion... By avafrankie in 8/10/2011 1:42:22 AM | Used the Cardinal Greenway from Marion to Muncie for the first time in my life and mostly the first time I had ever biked to a destination outside Grant County. Using the Muncie section of the Greenway is what really made the trip to Muncie very impressed. The Greenway between Gaston and Muncie has some bumps and uneven pavement but made it back to Marion safely (with two periods of rain) Best bike drive in Eastern Indiana in summation. So if you are planning a trip from Marion to Muncie, pack for weather conditions.
