How to Visit
The North Cascades Environmental Learning Center is located approximately 75 miles east of Interstate 5, at milepost 127.5 on the North Cascades Highway (Highway 20), on Diablo Lake in North Cascades National Park. The drive is slow but scenic as the highway winds through small towns along the Skagit River corridor. If traffic is light, we recommend allowing three hours travel time from Seattle, two hours from Bellingham and one-and-a-half hours from Winthrop.
