Diablo Lake Boat Tours
Come be a part of Skagit history! Seattle City Light has been offering the popular Diablo Lake Boat Tours for more than 80 years. Better than ever, the tours begin with a delicious, organic and locally-sourced lunch at the North Cascades Environmental Learning Center on the shores of Diablo Lake.

After lunch, your Skagit Tour Guides will lead you on a short guided walk to the boat dock as they talk about some of the area's natural history, biodiversity, and geology. You'll also learn about the unique relationship between the environment and the three hydroelectric dams, which provide clean, low cost, renewable power to the citizens of Seattle.

At the end of the walk you'll board the Cascadian and embark on your cruise of glacier-fed Diablo Lake. You'll experience parts of the lake that are typically hidden from view when traveling by highway or hiking on trails. Your tour will come alive with historic stories about the early explorers and settlers in the area and the formation of the Skagit River Hydroelectric Project. You'll learn about the wildlife habitat that surrounds the deep-blue waters of Diablo Lake, and you'll enjoy views of glacier-clad peaks, islands, and waterfalls. Whether this is your first time taking a Diablo Lake Boat Tour, or you've joined us many times before, this is a great way to experience the inspiring North Cascades landscape.
