Large I-90 corridor campground with 47 sites (45 ft max) along the Snoqualmie River near North Bend. Easy highway access, good cell service, family river recreation.
Tinkham is one of the largest and most RV-friendly National Forest campgrounds along the I-90 corridor, with 47 sites accommodating rigs up to 45 feet on gravel pads along the South Fork Snoqualmie River. Good cell coverage on major carriers makes it popular with families who need connectivity. Vault toilets and potable water are on site. Easy I-90 access via Exit 42 puts North Bend's restaurants and grocery stores 12 miles west.
Tinkham Campground sits in the South Fork Snoqualmie River valley just west of Snoqualmie Pass, where the river corridor serves as critical wild steelhead conservation habitat and the I-90 wildlife crossings above camp allow cougars and bears to safely cross the freeway. The Alpine Lakes Wilderness is accessible via trails from camp, and the surrounding Mt. Baker-Snoqualmie National Forest provides a forested buffer between the urban Puget Sound region and one of Washington's most beloved backcountry wilderness areas. Snoqualmie Pass above the valley marks the ecological divide between Washington's wet maritime west slope and the drier east-Cascades forest — a boundary that creates dramatic species diversity in the surrounding mixed forest just a 45-minute drive from Seattle.

Small campground on the South Fork Snoqualmie River — sites along the river (1–8) are the nicest with good swimming holes. Great base for Franklin Falls (3 mi), Snoqualmie Falls (25 mi), and I-90 corridor day hikes. Fills on summer weekends; arrive Friday afternoon to secure a river site. More intimate and quieter than nearby Gold Basin.
