The pontoon slips off the Salish Dock and the lake immediately widens, a calm plane of glass that dares the wind to stir it. As the boat moves toward Wild Horse Island, the Mission Mountains stand like a line of watchful guardians while the sun leans low, turning cliffs and water to copper. Passengers settle into shaded seats or edge closer to the rail, binoculars and cameras in hand, listening as the captain outlines the route and the island’s stories.

Bring a refillable water bottle

Secure cameras and small gear
Boat decks and gentle wakes can jostle items—use straps or dry bags for cameras and phones.

Layered jacket or windbreaker
