Diablo Lake & Lunch Tour
Come be a part of Skagit history! Seattle City Light has been offering the popular Diablo Lake & Lunch Tour for more than 80 years. Cruise past amazing scenery while you learn about the area's natural and cultural history and the Skagit River Hydroelectric Project which provides clean, low-cost, renewable power to Seattle.

Start your adventure by boarding the Alice Ross IV - a new boat designed especially for the tours. The cabin features a roof that is nearly all glass to allow for the best possible visibility. The boat also has a heating and air conditioning system, as well as an onboard head. A 14-foot open aft deck also allows passengers to enjoy the tour from outside.

As you cruise glacier-fed Diablo Lake you will learn about the surrounding wildlife habitat and enjoy views of snow-clad mountain peaks, islands, and waterfalls. 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 stories about the early explorers and settlers in the area and the challenges of dams and powerhouses in a very remote location. A 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 & Lunch Tour, or you have joined us many times before, this is a great way to experience the inspiring North Cascades landscape.

Reserve a spot now - the Diablo Lake & Lunch Tour fills up quickly!

Diablo Lake Afternoon Cruise
In response to popular demand, we've added the option of an afternoon cruise around Diablo Lake. This shortened version of the Diablo Lake & Lunch Tour is designed for folks who are arriving in the North Cascades later in the day or do not have a lot of spare time while they are visiting. This guided tour will be aboard the Alice Ross IV but does not include lunch or a snack.
