Baker Lake offers multiple boat ramps along its western shore for public access, with the PSE Kulshan (West Pass Dike) Boat Launch available year-round and featuring a moderate-grade concrete ramp with parking and nearby seasonal campground facilities.

Additional launch options include Horseshoe Cove, Panorama Point, Swift Creek, and Shannon Creek, each with varying conditions and amenities; some ramps have gravel surfaces and may require 4-wheel drive depending on lake levels and weather conditions.

The nine-mile reservoir provides excellent boating and fishing access in the North Cascades area, located about eight miles north of Concrete off State Route 20.
