The Paul Henry–Thornapple Trail: a railroad that took 170 years to finish
The Paul Henry–Thornapple rail trail follows the old Grand River Valley Railroad grade through Middleville and Irving, with a stretch carrying the North Country National Scenic Trail.
The flattest, straightest walking path in this part of Barry County is flat and straight because it used to carry trains. The Paul Henry–Thornapple Trail runs on the old roadbed of the Grand River Valley Railroad, a line first chartered back in 1846 that then sat dormant for two decades before anyone laid rail. Construction finally got going in 1868, and on the first day of 1870 a locomotive named Muskegon pulled the first train into Grand Rapids over the new grade.
A century and a half later the corridor is doing its second job. When it’s all stitched together the route will stretch roughly 42 miles, from Kentwood down through Caledonia, Middleville, and Irving toward Vermontville. Kent County and Kentwood Parks already manage a continuous paved stretch from Kalamazoo Avenue at 44th Street to Caledonia. Through Middleville the trail bends along Thornapple Road, hugging the river the town was named for.
Part of what makes this trail worth a detour is what shares the tread with it. The segment between Irving and Middleville is also a piece of the North Country National Scenic Trail — the 4,800-mile footpath that wanders from North Dakota to Vermont. So a quiet afternoon stroll on a Barry County rail trail is, for a few miles, a step on one of the longest marked trails in the country.
You get the usual rail-trail bargain here: no steep grades, because steam engines couldn’t climb them, and a corridor that cuts through farm fields, woodlots, and river bottom that you’d never see from a road. The crushed-stone surface suits bikes, strollers, and slow walkers alike. It’s the rare case where a railroad abandoned its tracks and the result was better than the railroad.
