Iron Horse Park access Access points to the developed portion of the trail, managed by Washington State Parks and Recreation Commission, are at: •
Rattlesnake Lake, Cedar Falls – western terminus and connection to the
Snoqualmie Valley Regional Trail • Twin Falls •
Hyak – provides access to the
Snoqualmie Tunnel through the crest of the
Cascade Mountains. In winter this site provides a public sledding area and ski trails groomed for track and skate style cross country skiing from Hyak eastward. Washington DOT Sno-pass parking is required at this site in winter. Within walking/snowing/skiing distance is a state parks owned lodge. •
Easton – descending the eastern slope of the Cascades •
Cle Elum – provides access to the Upper
Yakima River Canyon •
Thorp – near the historic Thorp Mill •
Kittitas, Washington – in the open farm valley of the Yakima River drainage east of
Ellensburg, Washington • Army West – at the western edge of the stretch passing through the
shrub-steppe country of the U.S. Army's

Columbia River Tunnels The trail features six tunnels, including the
Snoqualmie Tunnel, which was #50 on the railroad's numbering system. The other five tunnels in order are the Boylston (#45), Thorp (#46), Picnic Area (#47), Easton (#48) and Whittier (#49). The Boylston Tunnel was also known as the Johnson Creek tunnel to the railroad and sometimes tunnels #46 and #47 are known as the Thorp Tunnels.
Undeveloped drainage; the former railroad grade climbing the basalt walls of the lake can be seen Access points to the undeveloped portion of the trail, managed by Washington State Department of Natural Resources, have not been formally opened to the public. However, the trail provides access to the unique geological erosion features of the
Channeled Scablands regions of the state of Washington, and several stretches have been recognized as providing access to this area created by the cataclysmic
Missoula Floods that swept periodically across eastern Washington and down the
Columbia River Plateau during the
Pleistocene epoch. At Malden, once home to the largest railroad turntable in the world, Washington State Parks is planning a trailhead in the former rail yard. ==Iron Horse State Park==
