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.

To start your tour adventure, a Skagit Tours guide will lead you on a short guided walk to the boat dock as you hear about some of the area's natural history, biodiversity, and geology. You will 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 your walk you will 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. A snack will be provided on board the boat as you learn about the wildlife habitat that surrounds the deep-blue waters of Diablo Lake while enjoying views of glacier-clad peaks, islands, and waterfalls.

Better than ever, the tours ends with a delicious, organic and locally-sourced lunch at the North Cascades Environmental Learning Center on the shores of Diablo Lake. Whether this is your first time taking a Diablo Lake Boat Tour, or you have joined us many times before, this is a great way to experience the inspiring North Cascades landscape.
