The rock-climbing area is adjacent to the park, above the Iron Horse Trail. Rock-climbing equipment is necessary. Fatal accidents have occurred when amateurs have climbed without proper equipment.
Olallie provides access to the Iron Horse Trail, an old Milwaukee Railroad path that starts in North Bend and extends to the Idaho border. The Iron Horse Trail permits mountain biking and horseback riding.
The river is seasonally open for fishing. A recreational license is required for fishing and shellfish harvesting at Washington state parks. For regulations, fishing season information or to purchase a recreational license, visit the Washington Department of Fish & Wildlife website.
Kayaking only is allowed downstream of Twin Falls.
Twin Falls Trailhead
The Twin Falls Trail follows the South Fork of the Snoqualmie River through the rainforest along the western slopes of the Cascade Mountains. The trail is best known for viewpoints of Twin Falls. A little over a mile from the trailhead, a set of stairs descend to a viewpoint of the Lower Falls as they plunge over a 135-foot cliff. Hike another quarter-mile to a bridge that spans the narrow Twin Falls canyon for a view of the Upper Falls. The trail continues another mile where it intersects with the John Wayne Pioneer Trail. The Twin Falls Trailhead is also a popular river access point for fishermen and put-in for kayakers.
South Fork Fishing Access
A small trailhead, the South Fork Fishing Access provides fishermen access to the north riverbank of the Snoqualmie River’s South Fork. Rainbow trout, cutthroat trout and whitefish are the most abundant species of fish found in the South Fork.
Homestead Valley Trailhead
The Homestead Valley Trailhead provides access to a variety of outdoor pursuits. Hikers can use the John Wayne Pioneer Trail to access the east end of the Twin Falls Trail. Rock climbers can access the Deception Crags and the Mount Washington climbing areas which offer more than 100 routes that range in difficulty from 5.6 to 5.13b. The trailhead is often used as the end point for mountain bikers riding the John Wayne Pioneer Trail from the Hyak Trailhead through the 2.3-mile-long Snoqualmie Pass Tunnel and then another 12 miles downhill to Olallie.
South Fork Picnic Area
The South Fork Picnic Area has two separate picnic areas, one next to the Hall Creek Play Field and the other along the riverside of the Snoqualmie River’s South Fork and an interpretive trail. Both picnic areas have picnic tables and barbecue grills available at a first-come first-served basis. The Snoqualmie Wagon Road Interpretive Trail starts near the riverside picnic area and passes through a small grove of old growth trees to Weeks Falls. Interpretive signs tell the story of the Snoqualmie Wagon Road, the first road that ran from Ellensburg to Seattle in the late 1800s. The South Fork Picnic Area is also provides river access for fishermen.
Far Side Trailhead
The Far Side Trailhead provides hikers and rock climbers access to trails and crags in the Middle Fork Natural Resource Conservation Area. Visitors may hike along the 4.25-mile Dirty Harry’s Peak Trail to the 4,680 foot summit. From atop Dirty Harry’s Peak, visitors may take in views of the Upper Snoqualmie Valley to the west and the Alpine Lakes Wilderness Area to the east. Rock climbers have access to six separate climbing areas that range in difficulty from 5.5 to 5.12c.
Cedar Falls Trailhead (Iron Horse State Park)
The western terminus of Iron Horse State Park, the Cedar Falls Trailhead provides access to the 108-mile-long John Wayne Pioneer Trail and is the most popular route to the 1.5-mile-long Cedar Butte Trail in Olallie State Park. This family friendly trail provides a gentle hike to the 1,870 foot summit of Cedar Butte. The trail features views of the Boxley Blowout, a crater left in the hillside where a giant landslide and flood destroyed the downstream town of Edgewick in 1918.
