This 22.5-mile rail trail follows the abandoned Burlington Northern grade connecting the towns of Sedro Woolley and Concrete, and can be accessed from three trailheads off of the North Cascades Highway.

The Grand Canal is the older of the two inland waterways that were built to link Ireland’s capital, Dublin, to Ireland’s longest river, the River Shannon, in the midlands. Built between 1756 and 1804, the Grand Canal starts on the south side of the River Liffey at Grand Canal Dock in Dublin’s Docklands and heads west along what is known as the Circular Line where it joins the main line at Suir Road. From there the canal continues west out of Dublin, passing through County Kildare before crossing the width of County Offaly where it joins the River Shannon at the village of Shannon Harbour.
