Trail guide
Happy Creek Forest Walk is a 0.3-mile loop from the Happy Creek Trailhead on the south side of State Route 20. It winds through old-growth forest on mostly boardwalk, with a short gravel section. This is a good quick break from the highway if you want an easy, accessible forest walk; allow 15 to 20 minutes with a pause by the creek. It is too short to count as a substantial hike.
The boardwalk follows the southern half of the loop beside Happy Creek; the return has more gravel. The grade is shallow, and the whole loop is described as accessible. The wooden boards can be slick when wet, snowy, or icy. Leashed pets are allowed in Ross Lake National Recreation Area, with a leash no longer than six feet.
A much longer and steeper spur to Happy Creek Falls starts from the same access. It is a different walk, not an extension of this 0.3-mile loop. Published distances for the falls route differ, so check that route separately if you want to continue uphill.
