Intermediate trail. Ride Mr. Zig Zag counterclockwise out of Five Points Junction and get one of the best downhill rides in the park. Ride it clockwise and it’s an uphill challenge. Mr. Zig Zag is one of two true closed loops at MoMBA and one of the coolest ways to ride a mile and end up where you started. Like the name implies, Mr. Zig Zag winds through the forest without losing or gaining much elevation.
