Overview
Tolt-MacDonald Park is a King County park located near the small city of Carnation, Washington, roughly 30 miles northeast of Seattle. It sits at the confluence of the Tolt and Snoqualmie Rivers, giving it a distinctive natural character shaped by river bottomlands, forested uplands, and open meadows.
The park is best known among regional visitors for its suspension footbridge spanning the Snoqualmie River, its riverside camping, and a trail network that suits both families and more experienced hikers. It is a working example of King County's efforts to preserve open space in the fast-developing Snoqualmie Valley.
Because the park is operated by King County Parks, facilities, fees, and seasonal conditions can change. Visitors should verify current information — including camping reservations, day-use fees, and trail closures — on the King County Parks official website before arriving.
Before You Go
Permits and Reservations
Campsites at Tolt-MacDonald typically require advance reservations, particularly on summer weekends. King County Parks manages reservations through an online booking system; walk-in availability is not guaranteed. Check the official King County Parks site for current booking procedures and any day-use parking fees.
Seasonal Considerations
The park lies in a river floodplain. Winter and early spring can bring high water, trail flooding, and temporary closures — especially near the river's edge. Always check current conditions before visiting between November and April. Summer weekends are popular and the campground can fill quickly.
What to Bring
- Layered clothing; western Washington weather changes rapidly even in summer
- Rain gear regardless of season
- Insect repellent (mosquitoes are active near the riverbanks in warm months)
- Plenty of water, as potable water availability on trails should be verified locally
- A Washington State Discover Pass may be required for some parking areas — verify before arrival
Getting There
By Car
The park is located at the edge of Carnation, Washington, on NE 40th Street. From Seattle, take SR-203 north through the Snoqualmie Valley to Carnation; the drive is roughly 35–45 minutes depending on traffic. Parking is available within the park; verify any associated fees on arrival or via the King County Parks site.
By Public Transit
King County Metro and Sound Transit routes serve the broader Snoqualmie Valley corridor, but service to Carnation itself is limited and may not stop directly at the park. Visitors without a car should check current route maps on the King County Metro website and be prepared for a walk from any transit stop into town. This is primarily a car-destination for most visitors.
Things to See & Do
Suspension Bridge
The park's signature feature is a long suspension footbridge crossing the Snoqualmie River. It connects the lowland camping area to the upland trail network and is a highlight for visitors of all ages. The bridge offers good river views and is a natural photography spot.
Trails
A network of trails winds through forested uplands and river bottomlands. Routes range from flat, easy riverside walks to more moderately inclined forested paths. Trail conditions vary significantly by season — the lower trails near the river can be muddy or flooded in wet months. Pick up a trail map at the park or verify current conditions through King County Parks.
Camping
The park offers tent camping and group camping areas. Riverside sites provide direct access to the Snoqualmie River bank. Amenities typically include restroom facilities; verify what is currently available when booking. Campfires may be subject to seasonal restrictions.
River Access
The Snoqualmie River shoreline within the park is accessible for wading, wildlife watching, and general relaxation. Swimming conditions vary with river levels and are subject to safety considerations — no lifeguards are present. Use caution, especially during periods of high flow.
Wildlife and Nature Observation
The confluence habitat supports a variety of Pacific Northwest wildlife. Bald eagles, great blue herons, and various waterfowl are regularly sighted, particularly in cooler months. Salmon runs in the Snoqualmie system can be observed from the riverbank in autumn.
Practical Information
Fees
Day-use parking and camping fees apply; amounts are set by King County Parks and subject to change. Verify current pricing on the official King County Parks website before your visit.
Facilities
The park generally has restroom facilities and a picnic area. Availability of specific amenities (potable water, garbage service, RV hookups) should be confirmed directly with King County Parks, as these can vary by season.
Dogs
Dogs are typically permitted on leash. Confirm the current pet policy and any restricted areas when planning your visit.
Connectivity
Cell service in and around Carnation can be inconsistent. Download offline maps and any necessary reservation confirmations before leaving a reliable signal area.
Emergency Services
For emergencies, dial 911. The nearest hospitals and urgent care facilities are located in the greater Kirkland/Redmond area to the west; verify the nearest facility before your trip.
Safety
The primary safety consideration at Tolt-MacDonald is the river itself. The Snoqualmie River can rise quickly following rainfall, and currents that appear calm at the surface can be deceptively strong. Keep children and pets away from the water's edge during high-flow periods, and heed any posted closure signs.
Trail conditions in the lower areas of the park can deteriorate significantly in wet weather, leading to slippery roots, mud, and standing water. Wear appropriate footwear and be prepared to turn back if conditions become unsafe.
Wildlife encounters are generally benign, but store food properly in camp to avoid attracting raccoons and other opportunistic animals. Black bears are present in the broader Snoqualmie Valley region; follow standard food storage and encounter guidelines recommended by Washington Department of Fish and Wildlife.
