I decided to do this hike after perusing maps and wondering about potential hikes. Watson Lakes stood out as being a little isolated from other potential hikes. A little googling and searching of trip reports sealed the deal. A perfect weather weekend was in store and that's all I needed for the go decision.
Getting to the trailhead involves driving up the Baker Lake Road off of Highway 20, the North Cascades Highway. Off Baker Lake Road, right turn on Road 1106 to Kulshan Campground, and cross over the Baker Lake Dam. After crossing Baker Lake Dam, which is pretty cool, pavement ends and you continue relentlessly uphill on a well-graded unpaved forest road (Road 1107). The road is narrow so I was strategically and mentally logging potential pullouts for negotiating any opposite downhill traffic with some comfort knowing that uphill traffic has the right of way obligating downhill traffic to backup hill. That's the theory anyway.
I finally reached the trailhead at 11 am, two hours after pulling out of my driveway, excluding the Starbucks stop at Cooks Road. Plenty of parking at the trailhead, even on a sunny Saturday, maybe a dozen cars parked or less.
After crossing the meadow the trail entered forest again and climbed more steeply to another saddle. The trail then dropped down into the Watson Lakes basin crossing the official Noisy-Diobsud Wilderness boundary. The forest eventually opened at some large boulders offering a breathtaking view of the Watson Lakes pair and beyond to glacier-draped Bacon Peak in the North Cascades National Park.
