Once the lurk of urban BMXers in the early 2000s, this trail grew into disrepair until 2015 when restoration efforts began. It is now affectionately referred to as "The Underground" but remains a popular getaway for local city riders. Great for hardtailing, fat biking, or even BMXing.

It a little sandy at the south entrance but still rideable if you keep your speed up.

 Nice photos! But, were those really from the "Underground" in Grand Rapids, Michigan? I don't see any remnants of the lumber or the concrete culvert pipe.
