Come be a part of Skagit history! Seattle City Light has been offering the popular Diablo Lake Boat Tour for more than 80 years, and now in partnership with North Cascades Institute, the tradition continues on. On Diablo Lake Boat Tours, you will learn about the area's natural history, biodiversity and geology, as well as the unique relationship between the North Cascades environment and the Skagit River Hydroelectric Project, which provides clean, low-cost, renewable power to the citizens of Seattle.

The adventure begins by boarding the Alice Ross IV – a brand-new boat designed especially for Skagit Tours. The boat features a heating and air conditioning system, as well as an onboard head, and the cabin’s roof is mostly glass to allow for the best possible visibility. A 14-foot open aft deck also allows passengers to enjoy the tour from outside.

As you cruise the glacier-fed Diablo Lake, you’ll  learn about the surrounding wildlife habitat and enjoy views of snow-clad mountain peaks, islands and waterfalls. Experience parts of the lake that are hidden from view when traveling the highway or trails. Your tour will come alive with stories about the early explorers and settlers in the area and the challenges of building the three Skagit River Hydroelectric Project dams and powerhouses in a very remote location. A delicious snack will be provided on board.

The tour 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 an adventurous and enriching way to experience the inspiring North Cascades landscape.

The boat ride is pretty awesome,” wrote Terry Richardson, Travel Writer for The Oregonian. “It's as close as you'll get to seeing an Alaskan landscape in the lower 48 states.”


Towering peaks, unbelievable turquoise waters and a fascinating cultural and natural history are more than enough incentive to visit," wrote Jessi Loerch for the Everett Herald. "Skagit Tours will give you a good introduction to the region."


"We visited three powerhouses, and got to go inside one and back in time in two. We ate an amazing, locally sourced lunch at the North Cascades Institute and got a short-but-sweet tour of the nonprofit’s Learning Center on the shores of Diablo Lake... We climbed aboard a boat to get on the waters of Diablo Lake and take a closer look at Ross Dam," explains Amy Kepferle of the Cascadia Weekly. "I know there’s much more to what lies off Highway 20 than what you can see from your car."
