Poodle Dog Pass / Silver Lake is a 11 mile hike in Mt. Baker - Snoqualmie National Forest that will take about 8 hours to complete with Fido. The first 4 miles of the trail allow for a gentle stroll to the old mining town. Once past the town, the trail will have you ascending a series of switchbacks. Bring along mosquito repellent if you are hiking this trail from July through late summer.
