Description - Iron Horse State Park covers 1611 acres of land of which there are 66.5 miles of trail along the former railbed.
- The 66.5 miles managed by the Lake Easton Area extends from Twin Falls near North Bend above the Snoqualmie River valley, through Snoqualmie Pass, east along the Yakima River valley through riparian woodlands, dry coniferous forest, broadleaf forest, and open agricultural lands to Thorp. Here it connects with the Kittitas section of Iron Horse. The trail elevation descends from 3100' to 1500', not in excess of a 2% grade.
Within this area, there are thirty substantial trestles, four tunnels (one of which is 2.3 miles long), two snowsheds, three developed trailheads located at South Cle Elum, Easton, and a USFS area at Hyak.
The Easton trailhead has two vault toilets and five picnic tables, water, a loading ramp and a 21-vehicle parking lot.
Recreation - Non-motorized activities such as walking, bicycling, horseback riding, cross country skiing, dog sledding, and fishing are enjoyed in the park.
Climate - Washington's climate varies with each region. The Cascades split the state and alter weather patterns. Moisture bearing winds coming from the west give generous amounts of precipitation to the western slopes of the mountains, with wintertime snow above 3000 feet. This area has an average annual precipitation of 104 inches and an average wintertime snow depth of 87 inches.
Average maximum summer temperatures are in the mid to high 60s with a minimum average in the mid 40s. Because of the elevation and distance from the moderating oceans, winter temperatures are much colder than those in in the Seattle area, with minimum temperatures in the 20s and maximum temperatures in the 30s.
Iron Horse State Park is located in Kittitas and King counties along I-90. The Lake Easton section begins at Cedar Falls near North Bend east to Thorp.
