Forbes State Forest and the adjacent state parks (Linn Run, Laurel Mountain, and Laurel Ridge) maintain the PWS Trail System, a network of snowmobile trails and forest service roads though the second-growth forest along Laurel Hill. Much of this network serves as a mountain biking system the rest of the year. Bicycling is allowed only on the designated trails (and on roads open to automobiles). Bikes are prohibited on the yellow-blazed Laurel Highlands Hiking Trail.
The rail-trail segment of the system occupies the corridor of the old Pittsburgh, Westmoreland and Somerset railroad, which operated from 1899 until 1916. The abandoned corridor was unused until the trail opened in 1992.
