Red Town (Cougar Mountain) Trail is a 2.7 mile moderately trafficked loop trail located near Newcastle, Washington that features a great forest setting and is good for all skill levels. The trail is primarily used for hiking, walking, and horses and is accessible year-round. Dogs and horses are also able to use this trail.
From Seattle, E on I-90 to exit 13. Right (south) on Lakemont Boulevard S.E for 3.1 miles. Left into Cougar Mountain Regional Wildland Parks Red Town trailhead
Plenty of different routes and directions. Pretty view overlooking Renton at the southern face.
Without a map it was a bit confusing (a number of separate trails to form one loop). Well maintained trail, although there was some elevation gain. A bit harder than 'easy', but nothing strenuous per se. Nice scenery, but nothing really special.
