Red Lock Trailhead and Jaite Mill“You're nearing Red Lock Trailhead, where I'd choose the short Towpath walk to Jaite Mill for a little industrial history. Follow the level path south for about half a mile, then return the same way.”

Trail guide
This is a 5.25-mile loop from Red Lock, pairing a canal-side Towpath approach with the hilly, rocky Old Carriage Trail and a Towpath return. Plan about 2.5 hours. The mapped walk is 5.16 miles: follow the Towpath north for 0.7 mile to the first Old Carriage junction, climb into the woods, then return south along the canal. Other descriptions put the outing at 5.5–6 miles, likely reflecting different access or loop choices; this version includes both Towpath connectors.
The first part on the Towpath is easy walking. The Old Carriage section climbs steeply from the canal, changes from pavement to dirt, and winds through hardwood and pine woods along ravines. Expect rocky, uneven footing and a few bridges before the route descends to the Towpath. A signed spur is reported to make a small loop without a broad view, so don't count on a panorama as the payoff.
Near the initial climb, a low earthen embankment and shallow ditch sit beside the route. Their age and purpose aren't established, so they're best read as a striking feature in the woods rather than assigned a definite story. Stay on the tread around them.
The trail crosses land once part of Wentworth George Marshall's Rocky Run Farm estate, a large property with an arboretum. The old grade recalls its carriage-road past. Marshall was a Cleveland druggist and experimental botanist; the forested ravines now make this a quieter, more physical walk than a history stop.
Red Lock is named for a lock on the Ohio & Erie Canal. The small trailhead has 15 spaces and an accessible vault restroom; oversized vehicles don't fit. There is no identified water source at the lot or along this route. Dogs are allowed on leash up to six feet. The park classifies the hike as not wheelchair accessible.
Open map data marks three bridges on the loop as no-access, while current park trail information shows Old Carriage without a listed closure. A local notice about one footbridge described a temporary closure in 2022. That conflict may be stale mapping, but check posted signs at the crossings before continuing.
