About

Tinkham Campground is located along the South Fork Snoqualmie River in Mt. Baker-Snoqualmie National Forest, offering some of the most accessible camping in Washington's North Cascades region. The campground sits in abundant shade beneath Douglas fir, cedar, and western hemlock, providing a classic Pacific Northwest forest camping experience just off I-90. The 47 sites include standard nonelectric sites suitable for tents, trailers, and RVs, plus a few tent-only sites. Some sites accommodate vehicles up to 45 feet while others max out at 30 feet. All driveways are gravel back-in style. Each site includes a picnic table and campfire ring with grill. Amenities include vault toilets and potable water from a hand pump, though the water has mineral content that affects taste and color, so bringing your own water is recommended. Garbage service is available. Nearby recreation includes the family-friendly 0.5-mile Tinkham Discovery Trail, which winds through moss-covered fallen trees to a small pond. The surrounding area offers hiking, fishing, and horseback riding in summer, with skiing and snowshoeing opportunities in winter. Mount Rainier National Park is about an hour away for day trips.

Directions

From Seattle, take I-90 east to Exit 42. Turn right (south) across the river and follow Forest Service Road 55 for approximately 1.5 miles to the campground.
