Skagit, Washington Wild and Scenic River (Recreational) · Open Access
The Marblemount boat launch is available for all motorized and non-motorized boats for white water rafting, fishing or nature viewing along the Skagit River. A short trail from the parking area leads to viewpoints of the Cascade and Skagit Rivers. There is also a small parking area to the east that provides walking access to the east end of the trail and property. This is a popular launch in winter for rafts and drift boats accessing the Skagit River Bald Eagle Natural Area between Marblemount and Rockport. The Skagit River hosts one of the largest concentrations of wintering bald eagles in the continental United States.The launch will put you in at river mile 78.2.
From Sedro-Woolley, WA, take WA-20 East for 40 miles. Cross the Skagit River bridge at the town of Marblemount, and continue onto the graveled Cascade River Road. The boat launch is on the right just after the bridge.
